Your side of the computer repair experts

1. hard disk failure of the three responses
You sit comfortably in your favorite computer chair, and snapped open the display switch, then press the power switch. Greet you is the computer Kaga reassuring voice, and rotation of the cooling fan whirr. You a little later lying to the back of a chair and absently started looking at your old friend.
You think that you had, hundreds of problems are come to mind, why start the computer these days are so slow speed. And then the unfortunate happened. Hard endless sharp turning, and finally into a huge and disturbing noise. flash of the screen is \Do not be afraid. There are simple steps we style guide can help you recover all hard disk failure, plus the secret to the prevention of problems in advance. In your search for a screwdriver before try this.
Step 1: to soft
When your computer hard drive fails, the first thing to do is check the computer’s BIOS (Basic Input / Output System) settings. If the number of your hard disk capacity is not correct, the whole system may break the link. You may just need change some settings, will be able to solve the problem.
Check the BIOS settings
Press the computer BIOS configuration options can be exhaled buttons – usually F2 or DEL. According to the different BIOS manufacturers, you may see a further list of options, or directly into the place you want, but also namely: the standard BIOS options screen.
In the standard BIOS options screen, find the hard disk or IDE device options. Take a look at your hands hard drive specification table, and then check the BIOS in the SIZE or MB and so on, and then look at one number – the two should be very close, if BIOS settings and the actual installation of the computer’s hard drive size is inconsistent, then change some of MB. These settings must be correctly installed on the computer correspond to the actual specifications of the hard disk. or BIOS will think that the hard disk is broken.
If the number is not correct. Or where the number appears, it shows \hard choices (Auto). Select the item, then BIOS will check the hard disk, read the hard drive setup data, then automatically populate the data space.
If this does not work … … if you try the automatic identification (or your BIOS automatically try to), but the BIOS can not recognize the hard disk, then the problem is rather serious. This is a turn off on the computer, aside from the plug, open computer case time. roll up your sleeves to make a few basic hardware checks it.
Step 2: to hard
Before you open your system should let their contact with the computer’s metal frame to release static electricity to prevent damage system components. And then allocated to the computer’s power cord. (Note: If you open the computer and later at the station up and walk around, you have to plug then plug it back in, re-ground, and then plug pulled out to ensure that your body is not static.)
Check the hard disk connector
The computer’s shell apart, and then check the connection with flashlights on the hard disk connector. Hard disk itself has two connectors: Connect the hard drive and four-wire cable between the power supply connector, and connect the hard drive data cable connector to the motherboard. If the connector loose, and the still harder on – be careful not to bend the foot. The two cable joints are usually designed to only insert a single direction, so it should not be inserted wrong.
Also check the slender yet linked to a hard drive cable end, to ensure that it connected to the motherboard. If you find a loose connector, will it plug it back. If it’s interface is not as loose joints, and will it plug it back. If it’s interface is not designed specifically for the joints too, you have to carefully examine whether the board, printed with a small \Pushing their
Long electrical expansion and contraction, will lead to the connector pins loose contact with each other, just look at is undetectable. So when you open the shell, you can gently shake the hard disk and each connection on the motherboard connector – better way is to poke each connector not return again to restore the contact state. In addition, the bumper of your cable data cable for this test. If it becomes very hard, try for a new article – - There may be a package attached to an article of insulation inside the cable broke. but make sure you change the same type of cable. Once you have done these things, and plug the power plug it back in, start the computer, and then see what happens.
Step 3: Ultimate Countermeasures
You use the flashlight up and down according to all over the computer inside. You get to explore all the cable lines, re-insertion of joint, even looking from another wire. Hard but still did not move.
Call customer support department, which is to surrender and call customer support time. First try to ask your computer vendor, or the hard drive manufacturer’s technical staff. Maybe they will come across the same problem before, even talked about the way we have other than simple solution.
However, if finally found the sad fact is that your hard drive has been under a hell, please double-check after next – even if your computer has been a shelf-life, hard drive might still within the guarantee period. Although most computer vendors, the time machine in the sale offer one to three years shelf-life, hard drive manufacturers are usually two to five years to provide a guarantee. and their shelf life is usually not only on the original purchase cost of mailing the hard disk , should be able to change to a new hard drive.
To maintain the health of your hard disk
Finally, is to keep a healthy hard drive. Often similar to the ScanDisk tool and so the hard disk scan to check bad blocks, this tool has a Windows 95/98 Annex to the inside. It can help you avoid potential problems, or the problem becomes serious before, took them to get rid of.
2. Hard disk interface needle cause a malfunction
Breakdown phenomenon: I few days ago the system (WinXP) does not suddenly start up (my PC configuration: MSI KT333 +8233 A, West Czech Barracuda IV 60G), the phenomenon is stuck in the splash screen and can not enter the operating system. Start I did not take too much notice, that might be a problem with the startup files, repair what has become. But do not try a few times into.
Analysis solution: I think the virus might be trouble, trouble still after the virus. Reinstallation and start very slowly, and the hard disk light flash crazy. Into the system a bit after I test the hard drive transfer rate, found that second only 4MB! I think the issue of transfer mode, open Device Manager, and really hard work in PIO mode, strange, I am a hard working manual adjustment mode, reboot the system and found the mode Surprisingly, the hard disk PIO mode!
Basic problem here has been to find, hard to lose the support DMA mode. I go to the official website WestJet special tool to change the hard disk mode, but detect the hard disk at this time of the default mode is DMA, then use the West Czech disk error checking tool dedicated a full inspection. Everything was fine! I began to feel failure may be caused by hardware. carefully Attorney finally found the problem after a hard drive, IDE hard disk interface to actually broke a needle. I rushed with plum port The screwdriver unscrew the screw, outside the West Czech hard metal protection plate and sponge removed, exposing the circuit board, from other places to find a jumper pin, little pin up to the original place and weld. and then the hard disk recovery After reloading system troubleshooting.
3. Notebook hard drive failure analysis common
Start Fault
In the use of computers, we are likely to encounter computer does not boot. Cause system boot failure for many reasons, many of which are related with the hard disk. In general, when the hard drive fails, when, BIOS will Some tips are given information in English. motherboard due to different manufacturers or different versions of the BIOS, the information may be given prompt some differences, but basically much the same. Here we have to use the more common Award BIOS, for example, explore how to use the tips given information to determine and address the hard way not start trouble.
1.Hard disk controller failure (hard disk controller failure). This is one of the most common error, when this happens, they should carefully check the data cable connection to plug the existence of the loose connection is correct or hard drive parameter settings are correct.
2.Date error (data error). When this occurs, the system reads the data from the hard disk can not repair the existence of errors or bad sectors exist on the disk. At this point you can try to start the disk scanner, scan and correct sector logic error, if there is bad sector physical bad sectors, you need to try to repair using specialized tools.
3.No boot sector on hard disk drive (hard disk, no boot sector). This may be the hard disk boot sector is damaged, generally because of the hard disk boot area has been infected with the virus. In such cases must be first with the latest version of the antivirus software completely killing the virus present in the system, then, with such KV3000 boot sector recovery with such software, try to recover the boot record. If you use WinXP system can start the \\4.Reset Failed (hard reset failed), Fatal Error Bad Hard Disk (hard disk fatal error), DD Not Detected (not detected hard drive) and HDD Control Error (drive control error). When a prompt appears when any of the above, the general are hard control board, the motherboard is the disk drive interface circuit or the interior of the mechanical parts of a fault, this situation can only be requested for the corresponding control circuit professional maintenance or direct replacement of the hard disk.
Bad sectors fault
Through the above study, A King on the hard disk boot failure can not understand the solution, and then A is of course the King would like to know how to deal with bad sectors it has its own hard drive. Teacher this issue brief on the logic for the A King Bad sectors and bad sectors of the fault and the corresponding physical maintenance. but to lecture before the teachers to remind A King, must be careful to do this work carefully.
Logical bad sectors
Logical bad sectors there is the daily use in the computer vulnerable to a hard disk failure, the logical bad sectors the disk track is actually verify the above information (ECC) and servo-track data and information do not match. There such a failure main reasons are usually because of some procedural errors in operation, or where the magnetic media sector began a precursor to instability. logical bad sectors in the performance of general computer use, that is, file access error, or do hard disk cloning , when the parts reach the error, the result of an error message pop-up windows can not continue. eliminate the logical bad sectors of the method is simple, a lot of proprietary software such as: DM, NORTON of DISK DOCTOR can do so, but the most commonly used or the Windows built-in \operations will stay out of these sectors. Because use of these software more simple and also many have introduced here also, but more explained.
However, if the use of the NTFS partition and install Windows XP system, because it did not Scandisk this tool, it can only use the Chkdsk this tool. Chkdsk tool used for file-based systems, create and display disk status report. Another Chkdsk also to set out and correct errors on the disk. but if it does not take any parameters, chkdsk will only display the current status of the disk drive, and will not fix any errors, to correct an error, you must include the / f parameter.

Physical bad sectors
Physical bad sectors hard disk drive failure is more common. In fact, it is because of shock, scratches and other \fix up all the damage is too much trouble. because the track list in the internal hard drive, this sector is marked as normal, but also the physical existence of bad sectors. Therefore, it can not scan, format, low-grid or activation sector approach to be eliminated, must be the sector to set up a system within the hard disk reserves, to tell the disk has not used these tracks to the hard disk control system can be seen in the context of eliminating the bad sectors. Of course, do need to use some special software, in terms of maintenance on some of the difficulties of ordinary users.
But some hard drive manufacturers will provide the original software tool, such as IBM / Hitachi’s DFT and Western Digital’s Data LifeGuard Diagnostics. The original software tool not only scan speed, and identification accuracy is also high, to deal with the more common Physical bad sectors hard disk failure. Therefore, the internal hard disk or the original software to operate more reliable, unless the original instrument to solve the problem, or not recommended to use third-party tools.

1, infected with the virus due to
This is often manifested in the open IE, the IE interface, in the lower left box tips: Opening page, but Lao Bantian did not respond. In view the process in Task Manager, (enter method, the mouse on the taskbar, press Right m m process, the Task Manager) to see how the CPU occupancy rate, if it is 100% sure that is infected with a virus, then you want to run other programs is simply suffer. This is what we should look up the process of greedily taking up CPU resources.
Once found, it is best to record the name, then click the end, if not end, will have to boot into safe mode to remove the stuff, but also access to the registry, the (method: Start m Run, type regedit) in the registration Table dialog box, the point of editing m to find, enter the name of the program, found, right click delete, and then the search several times, often to completely remove the cleaner.
There are many viruses, antivirus software can do nothing, the only way is to manually remove.
2, and set the proxy server the
Some cheese, for some considerations, in the browser set the proxy server (Control Panel – Internet Options LAN set m m m connection using a proxy server for the LAN), set the proxy server is the network does not affect the QQ, because QQ using a 4000 port, and access to the Internet using port 80 or 8080. This is a lot of cheese they can not understand why the QQ, while the reason can not open the page. The proxy server is generally not very stable, and sometimes to the Sometimes not on. If there is such a setting, please cancel the agent on it.
3, DNS server error
explain
The so-called DNS, or domain name server (Domain Name Server), which convert the domain name to identify the IP address of the computer, such as the Shenzhen Window (www.sz.net.cn) the corresponding IP address is 219.133.46.54, Shenzhen Hotline (www . szonline.net) the corresponding IP address is 202.96.154.6. If the DNS server error, then the domain can not be explained naturally can not access the.
If this is the case, sometimes the network service access provider or ISP’s problem, called the Advisory ISP; sometimes the router or network card problem, not with the ISP’s DNS service to connect.
This is the case, can the router off for a while to open, or re-set the router. Or the card can not automatically find DNS the server address, you can try to use the specified DNS server addresses. In the network properties in conduct, (Control Panel m networks and local dialup connection to connect m m right property mTCP / IP protocol m property m using the following DNS server addresses). different ISP have different DNS addresses, such as telecommunications common is 202.96.134.133 (main use) 202.96. 128.68 (reserve).
Updated network card drivers or replace the card would be a thought.
Fourth, the system file is missing cause IE not start
This phenomenon is quite common, as:
1, the system’s instability manifested as frequent crashes, often getting reset, illegal shutdown causes the system file is missing;
2, software and hardware conflicts Changbiaoxianwei caused some programs installed network card driver conflict or conflict with IE. Since the introduction of Hyper-Threading CPU INTEL after, there is a prominent problem is that IE6 under XP SP1 and Hyper-Threading conflict;
3, virus, intrusion led to system files corrupted or missing.
If this is the first case, try repairing the system, 2K or XP system, put the original installation CD-ROM (Note: must be the original installation CD), running in at the beginning of m input sfc / scanow, press the Enter .98 in the system sfc command can also be checked.
If this is the second case, can be newly installed hardware or programs to uninstall, 2K or XP system can start after the machine, press F8, enter the Start menu, select \You can also use the system restore function, general can solve the problem quickly.
If it is XP system because of the reasons for hyper-threading CPU, Hyper-Threading disabled in BIOS, or upgrade to SP2. (Of course, XP SP2 to upgrade involves a lot of knowledge and pay attention to the problem, not go into details in this limited space ). this case, QQ TT comes with the browser in general to the normal view, can use a try.
If this is the third case, they have on the system tray full of killing the virus.
There is also a phenomenon also need to pay particular attention to: that is to open the site’s home page, but you can not open the two links, if so, the processing method is to re-register the following DLL files:
M run at the beginning to input:
regsvr32 Shdocvw.dll
regsvr32 Shell32.dll (Note that this command, first do not lose)
regsvr32 Oleaut32.dll
regsvr32 Actxprxy.dll
regsvr32 Mshtml.dll
regsvr32 Urlmon.dll
regsvr32 Msjava.dll
regsvr32 Browseui.dll
Note: Each input 1, press Enter. The second command can first do not lose, after the completion of these commands to restart windows, if found to be invalid, and then re-enter again, this time enter the second command. Also, if 98 systems to Microsoft’s Web site to download this file may be simpler, the file download address is:
http://download.microsoft.com/download/msn…us/mcrepair.exe
5, IE damage
If these methods do not work, it may be IE’s core damage, despite the system repair, can not make up, then reinstall IE is the best way for.
If you are 98 or 2K system, IE version if 5.0 is recommended to upgrade to 6.0.
98 of the system if you have installed the 6.0 upgrade, then the control panel, click Add / Remove Programs dialog box will pop up a repair, choose the default repair, re-start can be.
If 2K + IE6.0 or XP (comes with IE is 6.0) of the system, re-IE a little trouble, there are two ways:
1, open the registry, expand HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Active Setup \ Installed Components \ (89820200-ECBD-11cf-8B85-00AA005B4383), the IsInstalled DWORD value of 0 can be changed;
Note: reinstall IE does not necessarily solve the problem, only the idea of a deal with the problem only.
Recently found that many users can not browse the web like asking the question, really too many people asked, to address Members of the doubt, I have collected some information and you explore and how to exclude this fault. (Dao Beicha first) but of course even and we analyze the more common with the failure of a concrete analysis of specific need, you can refer to several situations to do the appropriate measures to bring hope to give you help. If you feel good, remember to help even the top look, do not let This post sunk, so that more people can see.
Case 1: the Internet can not browse the web but can use QQ to chat.
1, the browser \Solution: Set the correct access type. If the Internet through a proxy service, please fill in the correct proxy server IP address and port number; If not, please do not check the \2, DNS server settings wrong
Solution: If the ISP provider is assigned to your fixed IP address, then please fill in the correct IP address and ISP provided DNS server addresses; if the ISP provider is a dynamic allocation of IP addresses, so no need to fill in DNS server addresses; Another may be the ISP provider’s DNS server error can not correctly convert between domain rIP address, this time you can in your browser’s address bar, typing the site IP address, you can visit the website.
3, the firewall settings error
Solution: If the firewall settings properly, there may be barriers to exchange information with external networks, resulting in the failure can not browse the web. We can modify the firewall settings. What, how changes? This is not I say it. Ah, or say a few words, friends do not understand the direct election for the default level, select \Case 2: ADSL successful landing but could not visit the website of the fault solution
Should first PING ISP’s DNS server addresses, to see if PING pass, if PING pass, most of the software problems are the majority, if not PING pass, you should check the hardware device / line connection status and communication protocols (TCP / IP) < br />
If PING pass, you can see information similar to the following:
Command ING 202.98.160.68
Reply from 202.98.160.68: bytes = 32 time = 14ms TTL = 250
Reply from 202.98.160.68: bytes = 32 time = 27ms TTL = 250
Reply from 202.98.160.68: bytes = 32 time = 20ms TTL = 250
Reply from 202.98.160.68: bytes = 32 time = 17ms TTL = 250
If you can not PING pass, have the following information:
Pinging 202.98.160.68 with 32 bytes of data:
time out

time out
1. More computer friends, you can replace with another computer, replace the computer not to install any proxy server software, do not install any firewall, and only one network card installed and ADSLMODEM directly connected to ADSL dial the correct software installed. to see whether the normal view, if fault is caused by the client computer, if not, would need to detect whether the MODEM and the line normal.
2. Only one computer in a friend, you can stop the run all the proxy server software, such as WINGATE, SYGATE, WINDOWS’s INTERNET Connection Sharing (ICS), etc., can exclude a direct login to see trouble, you stop running proxy server software troubleshooting, it is certain that proxy service software problems.
3. Check your browser settings for IE in particular, for example, the most common cause of failure can not browse the web in IE, select the \Click Tools – \4. Check TCP / IP protocol of the property, in particular, DNS server settings are correct, Kunming, ADSL users can set the master DNS server: 202.98.160.68, secondary DNS can be set to: 202.98.161.68, particular note yes, dial-up software is different from the location of DNS settings are not the same, and some (in the dial-up network connection icon in the properties settings, some network settings in the Control Panel, some of the dial-up software (such as ENTERNET300) own property in connection Profile set. This 3 place to be sure to set the correct.
5. With WINDOWS friend, if after the tests have confirmed that is correct, be ready ADSL dial-up software and WINDOWS system disc, then remove the dial-up software first, then remove the Control Panel / Network and all of the TCP / IP protocol, restart the computer and re-add the TCP / IP protocol, and open the MODEM power, reinstall the dial-up software, tested, if the settings are correct, reinstall dial-up software and TCP / IP dial-up can be resolved after the most dialed the problem but can not browse the web. < br />
6. Replacement of a browser such as Netscape NETSCAPE browser test.
7. If you are directly connected to ADSL MODEM Internet access that computer, two network cards installed, try to connect local area network card first picked up, leaving only the ADSL MODEM to connect the network card. And then to see whether the fault exclusion, if troubleshooting , you should check the network and system resources. In particular, look at cards and other devices have no conflict (WINDOWS users in the Control Panel / System / Device Manager to view the equipment is normal)
8. Your network card to enable the BOOT ROM boot chip functionality, and network card with PXE boot after chip caused. Can be resolved:
① If the card is integrated on the motherboard, or the online activation process written into the BIOS, you can modify the system settings from the BIOS boot sequence, such as setting the first boot hard drive, or from prohibiting card BIOS boot the system. < br />
② If the card is not integrated, you can unplug the network card on boot or with a card chip to set procedures, prohibition of the network card BootROM guiding function can also be shut down, and then later in the boot, when there is \Press \Case 3: Sharing the Internet can not browse the Web
Machine with Windows XP, do the LAN proxy server and found the other computer can not browse the Web, but there is data flow, you can also use QQ, software, network, each machine can also be exchange of visits. Proxy server for dual network card, network Configuration wizard is set to \b NIC). client set to \and Broadband Modem connection), but the client only occasional bright light on what. In the opening pages, you can see in the status bar \Last Show \Solution: It may be your cable connection and DNS settings problems:
① to do a cascade line, will be a network card to connect directly to broadband ADSL, the other fixed.
② Set the IP address of other clients as 192.168.0.2,192.168.0.3,192.168.0.4 hh, subnet mask set to 255.255.255.0, set the gateway address for each client is 192.168.0.1, set the DNS for your The ISP’s DNS addresses.
At the same time, you can also consider a proxy server, if there is conflict between the NIC, A change of PCI slots, and other peripherals do not need to remove a temporary solution to the problem also has some help.
Common ADSL
of Flow
Page does not open, download interruptions, or online video and audio stream interruption, these are a lot of people will use ADSL Internet trouble. But when carefully examined the status of ADSL MODEM, the will dial-up login has been successfully found. So, what went wrong?
1. Line instability
If the home too far from the bureau (5 km) can be reported to the telecommunications sector. To ensure that the correct connections (voice separator different connection method is different, make sure the correct guidelines in accordance with the instructions to connect). While ensuring good quality line communications there is no interference, no lines to connect other cause interference devices, such as telephone extensions, fax machines, etc.. and check the junction box and crystal head and whether there poor contact with other wires around with string. conditional best to use a standard telephone line, if it is meet the International Telecommunication Union ITU standard three, five or more over five twisted pair. telephone lines after a separate walk-home. line go phone line to go the computer. If you want to install the living room ext, the best quality and good selection of junction box. PC access ADSL Modem with a twisted pair. (Note: The phone must not be placed next to the ADSL Modem, every few minutes because the phone will automatically search the network, then strong The electromagnetic interference is sufficient to cause ADSL Modem stop.)
2. Check your network card, if it is better to replace PCI ISA network card, and choose good quality card, the card may be too low causing the problem or 10M/100M culprit .10 M card can be adaptive. Other , the same two-card lead to conflict, concern, then, should be uprooted to connect local area network or other computer network cards, network cards only ADSL internet connection test, if the failure to restore the normal, check the two network cards have no conflict.
3.ADSL Modem or network card settings are incorrect
The most common mistake is to set the IP address of ADSL Modem, or an error set the DNS server. Because of the virtual dial-up for ADSL users who do not need to set the IP address is automatically assigned you can .TCP / IP Gateway generally do not need to set. Also, if DNS settings must be set correctly, if the operating system is Windows 9x, type in the DOS window Winipcfg obtain DNS address, in Windows 2000/XP, type ipconfig / renew, or ask the local telecommunications sector.
In addition, TCP / IP settings most likely to cause the situation can not browse the web, for example, has not changed settings, has been to the normal view, suddenly found here is not normal, you can try to remove TCP / IP protocol re-add the TCP / IP protocol.
4.ADSL Modem Synchronization exception
Check your phone line and ADSL connection is poor contact areas, or a phone line problem. If you suspect a bad splitter or ADSL Modem bad, try not to use separator directly to an outside line access ADSL Modem. If you determine separator is no problem, to ensure that splitter and ADSL Modem connection should not be too long, too long, then synchronization is difficult. If the exclusion of the above, as long as the weight from the ADSL Modem can solve the synchronization problem.
5.
Dial-up software mutual interference
ADSL Internet access the way the virtual dial-up and dedicated access to two types of ADSL users are mostly individuals with the former. And PPPOE (Point-to-Point Protocol over Ethernet Point to Point Protocol over Ethernet) virtual dial-up software have their own advantages and disadvantages. After many tests on different operating systems, if you use the operating system is Windows XP, recommended PPPOE dial-up software comes with it, less of Flow stability is also enhanced. If you are using Windows ME or 9x, can be several virtual dial-up software mmEnterNet, WinPoET, RasPPPoE. which, EnterNet is a commonly used now, EnterNet 300 applies to Windows 9x; EnterNet 500 apply to Windows 2000/XP. When you use a PPPOE dial-up software has a problem, may wish to uninstall the software for others to use a PPPOE dial-up software, make sure to be careful not to put in multiple PPPOE software to avoid conflicts.
6.
Other software conflicts
Uninstall the software could lead to drying up, and now find that some software such as QQ 2000b, etc., occasionally causing the Internet drying up, and under what conditions trigger specific, yet to be further tested. Many users find that after unloading stop solved the problem , including the use of ordinary Modem 163 dial-up users of this method is also useful to solve the drying problem situation, I also received e-mail a friend stop to reflect upon unloading QQ solve the problem, so if you have QQ, you may wish to uninstall OICQ , and then try the Internet. When you open some of the software have found that the phenomenon of drying up, shut down the software on all normal, try to uninstall the software.
7. Virus attacks and firewall software settings properly
Although attacks by hackers and viruses are less likely, but do not rule out the possibility. Virus associated components, if damaged ADSL will stop the phenomenon to occur. Recommended that you install the \\phenomenon should check the installation of a firewall, Internet sharing proxy server software, Internet software, speed up, stop running such software, then online test to see whether the rate of return to normal.
To sum up the time, the Internet can not browse the Web is one of the most common faults, the specific number of complicated factors, the solution is different. We can be: soft and then hard after the first system, the first after the complicated simple, binary search reduce the fault coverage. concrete has the following main steps:
The first step: exclude accidental, unforeseen failure
Just-do, the first cold start the computer and modem, rule out the possibility of occasional, unforeseen failure, such as software conflicts, memory disorder, ADSL Modem automatic disconnection, IP adjust the automatic disconnection, equipment, sleep, etc. problem. still OK and then asked each other or other normal computer can browse the Web, judgments are common problems or personality problems. If the problem is common on the Internet can only be resolved by the ISP, will have to check the server on the LAN or network line. If personality problems, it can focus attention to the network and the machine up.
Step two: identify the problem areas preliminary
Check with the command ping judge. Main ping the following address: One ping the machine loop address (127.0.0.1), if the show Reply from 127.0.0.1: bytes =?? Time =? Ms TTL =???, said TCP / IP protocol to run properly, if the show Request timed out (timeout), you must reinstall the agreement. Second, ping the local IP address. using the ipconfig command (9x system should enter winipcfg) view of the machine IP address, that if the General Network adapter is working properly, or may be network card, Modem problems. Third, ping the computer with the segment address. If the network links that the paragraph in question. If the networks have gateways, routers, will have to ping each paragraph with Ben Wang and other segments of the IP address connected to the port to determine whether failure. Fourth, ping the primary, alternate DNS server and Web server address, if General contact address with the network or ISP.
If the address can ping through, you can determine the operating system and browser’s fault. If the interruption occurs during time-out error (to take into account server may set the case against ping), show that the network unstable, packet loss, For example, a LAN broadcast storm may produce intermittent, it is usually the network connection, configuration errors, or user to its excessive.
The third step: rule out the possibility of \First check the network configuration. Check TCP / IP protocol setting case, network card, Modem and other equipment of the parameter settings, focusing on IP address, gateway, DNS address is correct, if wrong then return to normal settings. Inspection Agreement , the network adapter is excessive, proposed to delete the \. Check whether the error set up dial-up adapter IP address, because the upper hand in the traditional dial-up IP address is assigned automatically, configure the network card in the computer when it is possible to set the network card on the fixed IP address set in the dial-up adapter error , will lead to dial-up Internet access. check whether the dial-up ISP requirements related settings, such as dial-up numbers in some areas, the user name and password to adjust, and to 16300,16900 so.
Second, check card, Modem device driver is such a problem, if detected in the Device Manager have yellow! Or?, To re-install the matching driver.
Third, check whether the system is infected with a virus. Antivirus software will upgrade to the latest version of comprehensive anti-virus.
Step four: rule out the possibility of \First check the network card, modem, etc. all are working properly (it is disabled). Check overheat job instability, such as light through Modem, LAN indicator is working correctly observed (control instructions, etc. observation). with the replacement method (for this device to another device or computer test) to check whether the network card, Modem poor quality or compatibility.
Second is to check whether the network interface failure. Check the board (such as network card) is disabled. Board, line, RJ-11 and RJ-45 cable connector plug for many, too much dust, aging may lead to false then , loose, power could be shut down after the cotton removed with an eraser or alcohol test, re-plug, or another slot, interface, try, or re-connection lines and isolation with insulating tape reinforced or replaced. RJ-45 interface, for example, often to loosen the situation, can Crimping Pliers reinforcement.
Third, check whether there is smooth outside. If the phone line, check whether the normal telephone line can be on the phone into Modem cable to listen to whether the dial tone telephone, or direct dial-up test. From the ISP to the ADSL filter this connect any device to join will be harmful to the normal transmission of data, so before the filter and do not answer the phone, a device such as phone theft fighting. If the old-fashioned Modem Internet access, telephone features can not open the security fight. Check ADSL Modem points frequency is connected correctly, that phone into the wireless access divider Line mouth, telephone or fax machine connected Phone mouth, broadband access ADSL modem telephone line port.
Fourth, check the voltage is stable, the ambient temperature is too high (low) and the network line is busy.
Step Five: troubleshoot your browser,
Repair your browser. The browser settings back to the default values of all and try and remove set elements. Fix the browser can use the \Try to install other browsers.
Sixth step: Eliminate operating system failure
First fix registry. As to visit a malicious website may lead to the computer registry to be changed, not the Internet. Through the registry repair devices, Internet assistants and other tools or scanreg / restore command to repair the registry.
Second, turn off the other part is already running may cause conflicts in the memory-resident program (or process), close or disable other devices (such as other network card, Modem, shared resources related equipment, etc.), and then try whether the Internet. < br />
Third, check the operating system file is damaged. With a Windows System File Checker checks (win98′s use sfc, win2000 and above with sfc / scannow), if the destruction was prompted to restore.
Fourth, reinstall the operating system. From the perspective of data protection, it is recommended covering the installation, if not yet ready to solve the problem in the driver installation disk, a backup of important data backed up (preferably first system partition Ghost), under the premise of , format install the operating system.
Do not mind a small sum up it again, DNS server settings wrong, TCP / IP protocol error, this is the most common error. You need to first check the dial-up network, the master DNS and secondary DNS for errors, attention here is to check \Dial-up Network \a phone call on it. What, you do not know what they call? I do not know, I have a problem regardless of the village, playing 110 on it, or free of charge. you can try it. do not ask how to set up DNS I had it, trouble will not be a friend tell a friend, I on behalf of the party and the state had to salute you.
Let me say the following as TCP / IP protocol problems caused by the fault, if you checked these settings and found no error set, but still can not browse the web, then you should check the \Double-click \The following network components are installed \t dial-up network adapter
tTCP / IP
Here special attention to two points: First, if repeated here to install two network adapter or dial-up TCP / IP, the result can not browse the Web, how to see a repetition of it installed? If the repeat dial-up network adapter installed, You will see a line that says \If you find such a line # 2, please works …

1, the revised label can not always save, press save on a warning dialog box appears, click OK after the software shut down.
Cause: The user changes directly on the label changes when the error operation caused.
Solution: modifications in the correct way to modify the changes that you want to modify the contents of the double-click in the original layout of the dialog box to modify the time to write, do not allow the above changes directly in the label. This changes after the return to normal.

2, the printer does not normally take the paper, only went half-sheets, after printing a solid red (Zebra plant)
Cause: The printer parameter setting error.
Solution: The Z4M machine as an example. Click on Start Menu m> Set m> Printers m> Select Z4M machines m> right-click m> attribute m> printing preferences m> Document Optionm> Dispense Modem> select Tear Off to OK the .
3, the printer print all the lights flashing and can not test the paper (Zebra plant)
Cause: The sensor fault.
Solution: clean the sensor surface dust or replace sensor.
4, the printer will print a small label in place, and print the contents of partial or total up down side
Cause: The label is too small, the sensor sensing the paper is difficult.
Solution: General tab high for at least 10 or more should we do more than position, or we need to be offset on the label set. During label settings, the label’s high set a 5mm taller than the actual label around, and then in accordance with specific migration situation on the label offset set.
5, when legible printing, bar code is not clear
Cause: The bar code is too big, the density is too small.
Solution: reduce or increase the content of bar code bar code density. 200dpi and 300dpi for the machine, the bar code density is generally more than that in 7mils scale factor to 2 or 2 above, print out the bar code was clear.
6, print label, overall print some words do not come out
Cause: The print head is dirty, wrong layout.
Solution: Clean the print head; another time to see whether the layout of the printed word to overlap, and re-layout.
7, when the printer always appear in print without paper or not ribbon (TEC-572)
Reason: not to run out of paper or ribbon; send operation command caused the error.
Solution: Check whether the right under the paper or ribbon; parameters of the machine to be fine, and then printing software to print the correct layout settings.
8, print to print is not clear, ribbon off. (105Se/SL)
Cause: The printer ribbon shaft failure.
Solution: the machine shaft ribbon pull too tight, adjust the printer ribbon shaft under tension.
9, the new file can be printed correctly, but the old file is not open, can not print.
Cause: network printing, permissions error.
Solution: Print the time to see whether the network has opened the file, if opened, must first turn off to the other computer open. And then detected under the network permission issues.
10, print the contents of print incomplete.
Cause: The print version of the software and driver is too low.
Solution: Install the new version of the software and drivers.

19, during thermal printing, the first stop of the rotating shaft, and display ribbon exhausted.
Reason: bad machine PCB-G

Graphics computer system is one of the important parts, it will be CPU processed data signal, \not high, but with the application number and performance of the upgrade, graphics card failure rate is also increasing. while the monitor as the main output of the computer equipment, its quality is directly related to use of good or bad effect, but it is – Some of my friends are still relatively unfamiliar. Here’s the real failure on their common \graphics driver not properly installed
we install graphics driver, we often encounter the prompts to install the failure of trouble, and different versions of the driver does not work, how to correctly install the graphics driver then? (1 ) when the machine starts, press \, in particular, Matrox graphics card, when this is set to \After the operating system installed, be sure to install the motherboard chipset patch, especially for the use of VIA chipsets, the motherboard must remember to install the latest patches 4IN1. (3) install the driver: Go to \Manager \Programs \Find in the pop-up window to find the folder where the driver, click \Click \not in place, often also cause driver installation errors, so when installing the graphics card, be sure to pay attention to fully inserted into the AGP graphics card slot cheat.
2, black screen when the computer starts fault
start the computer, if the display phenomenon appears black, and the case sent a long two short horn alarm sound, the note cards is likely to lead to failure. First of all, to ascertain whether the failure caused by poor contact as graphics: turn off the power, open the case, the graphics card to pull out Then use the hair brush to clean the dust on the graphics card out, especially pay attention to the graphics card fan and heat sink to dispose of the dust. then wipe board with eraser back and forth a \will be re-installed graphics card (be sure to baffle and tighten the screw), to see whether the fault has been resolved. In addition, the display card for poor contact, such as poor quality of the chassis number of the gap behind the baffle and the motherboard AGP slot can not be aligned , in force on the screws tight graphics card after a period of time may cause deformation of graphics card PCB fault, try to release the video card as long as the screw. If you use the motherboard AGP slot is not very good material, AGP slot and the graphics card PCB can not be in close contact, you can use duct tape to show card door fixed, not sure if it is put that graphics card is installed on both sides of the chassis, the display card in the middle baffle. If you display card cheat oxidation problems encountered, and the use of rubber clean rust stains after display card does not work, then you can use the rust cleaning the finger, then gently before putting in the cheat on a layer of solder, to increase the finger thickness, but must be careful not to short circuit between the adjacent finger.
if not solve the problem by the above method, then there may be graphics card and motherboard compatibility issues, then you can also get a graphics card plugged into the motherboard , if the failure to lift, it indicates compatibility problems. Of course, users can also plug the card in another motherboard, if not failure, it indicates this card does exist with the original motherboard compatibility issues. For this failure The best solution is for a graphics card or motherboard. there is a situation worth noting is that graphics hardware problems, and generally display memory chip or burn, it is recommended graphics card to try to get another machine If the problem can only confirm that the graphics card replaced.
3, shows the failure
Huaping Huaping is a common graphics display failures, most of the graphics Huaping failure caused by graphics card itself. If display, then turn on the Huaping should first check the card is not the existence of heat dissipation, hands touch the memory chips, temperature, graphics card fan to see whether the stall. again to check the motherboard’s AGP slot and dust to see whether the oxidation of cheat cards, and then can get rid of the dust situation, with the eraser to the oxidation of part of the finger polish. If the heat does have problems, we can use another fan, or in memory the installation of the heat sink solutions. If you are playing games or doing 3D, then when Huaping, we must take into account is not due to graphics drivers and the process itself or the driver is not compatible with the existence BUG caused, and can change a version video drivers to try. If the above does not work, you can try to refresh the graphics card BIOS, graphics card manufacturers to see if there are no home page to download the updated BIOS. but to pay attention to – the same firms the same type of graphics card BIOS file often it is not the same, so that BIOS update or a certain risk.
is also the case, because the display or video card does not support high-resolution display Huaping often also cause failure. When such a failure that we can Switch boot mode to safe mode, in Win 98 into the display settings, in 16 color mode Click \, and then restart the computer to. of course, can also be in a pure DOS environment, edit the SYSTEM.INI file, display.drv = pnpdrver to display.drv = vga.drv later, save the file out, and then update the driver in Windows in procedures that solve the problem. In addition, the expanded memory can easily lead to improper Huaping, in order to avoid trouble – should be used in the expansion of the same brand memory, the same speed memory.
2, CRT monitors common failure
will be most commonly used or CRT monitors, but with longer duration of use, CRT monitors internal components will change some parameters, resulting in display fail, many of these failures can be by adjusting the display of some internal stressed components solve. But since there are high voltage power supply monitor, relatively serious problems have been detected should be sent to professional maintenance point of maintenance, rather than their own dispose, in order to avoid fire, personal injury, and dangerous.
1, display appears color cast problem
display there is the phenomenon of color cast we often encounter problems, the causes are: display near the magnetic materials are magnetized; moving display, to let the machine deflection coil shift, and produce color pure bad; degaussing circuit failures. of course should first rule out the graphics card and display the signal line, a lot of time to signal poor contact will result in display color cast problems arise.
and in most cases is likely to be magnetized led display . CRT display will be a strong magnetic field the magnetization what color cast problems arise, such as bass speakers without magnetic shielding, are generally good with some of the degaussing monitors its own function, but a bit more serious magnetization can do nothing. then you need to use special equipment to degaussing. deactivators can be purchased can also be made. But no matter what kind of degaussing law, his friends would pay attention to safety. degaussing device is powered hand constantly shaking, and gradually close to the screen, on magnetic parts can be repeated, and then back while shaking degaussing device side to about 2 meters away from the screen and then turn off the power. every time power should not be too long, if the bad effect of a degaussing can be repeated several times.
if After moving the display as the color offset caused by the problem, we can open the back cover will display deflection coil back to its original position, and deflection coil screw can be tightened. degaussing circuit for damage due to machine due to poor color purity can be first check whether the damaged thermal demagnetization resistance, to remove it, use the hand like a \at 8 ohms or more than 50 shows demagnetization resistance in Europe and the RTC components are bad, there is no way the only renewal. as degaussing resistor normal, then it should focus on examination of degaussing coil wire, plug, socket whether between loose and poor contact problem.
addition, there is a very easy to overlook the failure of reason – too much dust can cause the screen display when the reddish white! such failures have occurred within the warmer color temperature display (Many monitors can set your own color temperature), so that the white face (and similar color) reddish failure is best to first clean your screen and then click Check for other, if the fault disappears – you can walk less tortuous path it! Of course, some models of the brightness value is set too low will cause the \display refresh rate can not be adjusted, I am afraid my friends have encountered it! can not adjust the monitor refresh rate actually mostly because we do not choose the correct display type or video card driver is not installed correctly created. Display Type Selection often easily overlooked, and many users will display type is set to \does not recognize the display, should be the default state according to the most conservative set (60Hz). The solution is in the Display Properties, select the correct display type, if you are using Windows does not recognize, and I could choose a performance close to product substitution. If the reason for the driver, the user can re-install the drivers, because sometimes suddenly crashes, the card’s driver is lost.
Again, the display refresh rate not set too high, exceeding the standard refresh rate too much, does burn display or shorten its life. this display is best to install its own drivers, do not blindly use the high-end display driver. Second, Windows in \Do not remove, or cause users to use the monitor does not support the refresh rate.
3, display screen will display jitter sometimes inexplicable failure
shake up the screen and you keep seeing the jitter can not know For whatever reason, is not it annoying ah! this state will cause eye fatigue of computer users, computer users over time will be brought to the eye. caused by reason of such failure in the following areas: (1) bad power supply or power supply equipment has been aging: often no-name computer components used in power supply, material is bad, likely to result in poor or Gongdian computer capacity to keep up the circuit, when the system is busy, the display screen jitter in particular, appears phenomenon. computer when the power supply equipment is aging, are likely to cause the same problem. (2) Monitor refresh rate settings are not correct: the monitor resolution and refresh rate is set too high or too low, then such failure may result in , so you can set the resolution and refresh rate try intermediate values (Note: long-term work on overclocking the state will occur in certain components of aging and failure, but quite difficult to find the point of failure). (3) video card connection problem : Heavy inserted display card, failure can be resolved. (4) virus trouble: Some computer viruses may disrupt the display. (5) Windows 95/98 system write cache after the cause: If is for this reason that in the Control Panel → System → Performance → File System → Troubleshooting disable the drive after all the write-caching, you can solve the problem. (6) damage to the power filter capacitor: open the case, if you see power supply filter capacitor (the biggest kid on the circuit board capacitor) Top muster shows have a bad capacitor. another capacitor problem solving. (7) speakers and monitors placed too close: Some of the speakers will interfere with the magnetic field effect display properly. (8) power transformer and chassis from the monitor too close: Many peripheral power transformer (scanner, printer, etc.) work will cause more electromagnetic interference, causing screen jitter. the power transformer on the chassis and the monitor away from the place, the problem can be solved.
3, liquid crystal Monitor Fault
1, the water ripples and Huaping problems arise
first thing to do carefully check whether there computer peripheral sources of electromagnetic interference, and then replace a graphics card, or receipt of another computer monitor, confirmation card itself is no problem, then adjust the refresh rate. If you exclude the above reasons, it is possible that the quality of the LCD monitor problem, such as the thermal stability of the bad issues. wave of water is a liquid crystal display appears more common quality problems can not be solved, the proposed replacement or repair as soon as possible.
some LCD Huaping occur during startup problems, gives the impression as if there are high-frequency electromagnetic interference, like writing on the screen is fuzzy and jagged. This phenomenon is generally due to the graphics card does not have digital interfaces, and through an internal digital / analog conversion circuit and the VGA connector on graphics card. This form of connection although the signal matching to solve the problem, but it brought susceptible to interference there distortion. The reason is mainly because the LCD display itself is difficult and the input clock frequency analog signal synchronization clock to keep one hundred percent, especially in the analog sync signal frequency of the changing times, if the LCD monitor at this time synchronous circuit, or connected with the graphics card sync signal transmission lines appeared short circuit, poor contact and so on, can not be promptly adjusted to maintain the necessary follow-up synchronization relationship, then the problem occurs Huaping.
2, Display resolution rate set incorrectly
principle as LCD and CRT monitor display is completely different, it belongs to a direct one correspondence of pixels displayed. work in the best resolution liquid crystal display under the analog output of the graphics display signal through processing, transformation to the specific address information (the pixels on the screen of the absolute address) of the display signal, and then into the LCD panel, added directly to the display signal corresponding to the pixels on the drive pipe, some with memory search similar sites and write. so LCD screen resolution is not arbitrarily set, but the traditional CRT monitors support for the resolution of the more flexible. LCD can only support so-called \real resolutions to show the best image. When set to true resolution Yiwai resolution, generally by increasing or reducing the scope screen, display results remain unchanged, the excess is a black screen dealt with. Yejing display work in low- Under resolution 800 * 600 when the pixel if the display is still one correspondence with the display, then it can only screen in the center of the screen narrow the center of that 800 * 600 pixels to display, although the picture is still clear, but the display area is too small, not only in the sense that not too comfortable but also more expensive liquid crystal display panel is a tremendous waste. Another interpolation method can also be used, regardless of what resolutions remain in full-screen, but this time display will be greatly reduced. Also set the refresh rate of LCD picture quality with a certain relationship. my friends according to their actual conditions, set the appropriate refresh rate, normally set to 60Hz or better.

Printer ribbon is more familiar with a printing supplies. From the earliest mechanical percussive English printer to the computer later pin printers, printer ribbons are used. Printer ribbon works is to use stylus printer machine within the first English typewriter or dot matrix firing pin hit parts of the letters to hit print printer ribbons, produced at the printing paper printing.
the composition of the printer ribbon is very simple to knit and nylon fiber as raw materials percent of the ink soaked through with base, made of stain. good printer ribbon, with a base hit should be durable, elastic large print can not afford long hair, keep lines, can not afford to lotus leaf edge. It’s performance was mainly base surface is smooth with no protruding fiber end, Density uniform and tight, cutting edge straight and uniform, no char, rather than the phenomenon. hand touch: a good band-based soft and delicate, there is a sense of smoothness. tensile and good elasticity, recovery is good. bad break spinning printer ribbons based powerful, touching hair feel hard time, cutting edge uneven, with a side of char, rather powerful, flexible when drawing small, poor recovery, printing often entrainment, easy from lotus leaf edge, resulting in blocking the needle, cartridge and other phenomena.
apart with a base, the ink printer ribbon is an important factor in good or bad. good ink particles is very small, will not lead to plug pinholes, good liquidity, PH values are uniform, when coated ink absorption is strong, moisture is good, durable playing and printing the color transition slowly. good organic non-toxic inks will not corrosive, does not smell, after transfection with non-sticky, easy to dry. bad ink particles large, thick sticky hands, stained with quit after the hanging, produced between the adhesive tape was powerful, easy to plug the pinhole when printing, so that the needle can not be flexible and stretch, which will break the needle. it is to judge the use of high-quality ink printer ribbon hand to touch when the fingers will not leave obvious traces of ink. before and after the printing is not very significant differences. and inferior ink, when the hand touch feeling greasy fingers full of ink marks, appears to have enough ink, but the color will appear in print Shique important phenomenon, that is touching a piece of printing paper will be fuzzy. will not only result in poor quality printing inks are poor, and it can also print the needle along the pilot hole into the printing and curing scalp sutural, plug the printer needle, causing the printer can not print properly, serious cases may result in increased resistance of the print head out the needle and needle broken print, print needle parallel to the tank was crushed, the print head or printer ribbon motor driver chips were burned and other serious fault.
a brand name of the original printer ribbons, but tens of dollars, the damage caused by the printer is the loss of needles heavy, so users do not get petty at the time of purchase, thus runs the risk.
used for photo printing dye-sublimation card printer supplies is sometimes also called the printer ribbon, but it works and the prices of our daily said printer ribbons are two different things, should not be confused.

Asked a friend to see printer problems more Featured Articles sorted out many posts / inkjet printer / Laser Printer / Dot Matrix Printers / common failure order set, fault type are not necessarily but mostly learn, and I hope to play next to all categories Pass / TELL role is the intention of this post, and please give teach master to make the posts more typical ~~~~< br> a general failure to judge the printer as follows:
first is the use of the printer self-test system to measure, through the printer comes with a light or buzzer sound to be judged, in which light can indicate a basic failure, including the lack of paper, lack of ink, there is no power and so on. Next, can line observation, detection of the printer cable from the start (including the port, channel, print line detection), and then analyze the internal structure of the printer (including the care of paper planes, into the mouth of paper, print first class) to see whether the correct components to work for different fault lock situation related parts, components and then determine the existence of the problem. again, you can use the test method, test or partial test page inside the printer to print documents, to see cause of the malfunction. of course, another fault is the printer software failure, a similar failure on the need to by upgrading the driver, or visit its official website solved.
specific approach:
(l) the printer power cord is connected or the power light is lit and reliable. Check power supply and power cord, turn on the power, see power supply indicator is correct.
(2) the connection between the printer and the computer, the reliability of cable connections, check and re-connect the computer and the printer cable.
(3) whether the normal printer drivers: If you do not use the printer and install the drivers, or that the driver is not correct, there will not normally print fault.
(4) serial parallel port settings are correct: the BIOS to use the port in the printer and software to open the printer port is set correctly, should use the printer port is set to \print port signal. then should print port is set to \
(7) whether the virus causes: use of virus scanning software to check for viruses.
(8) See the printer’s hardware: a look at the printer ribbon, print head, paper placement, etc..
If the above method can not solve, the best is to ask a professional maintenance staff maintenance.
printer troubleshooting methods
1, printer output blank paper
for stylus printer rise to printing paper, usually because the blank dry ink ribbon, ribbon pull off, the print head damage, etc., should be replaced or repaired the print head ribbon; for inkjet printers, mostly caused by the failure to print the blank is due to nozzle clogging, no ink cartridges, nozzles should be cleaned or Replace the print cartridge; while for laser printers, such failure may be due cause is not bothered by imaging the toner roller (imaging roller DC bias is not added), it may be photosensitive drum is not grounded, so that the release of negative charge can not gravitropism , the laser beam can not play a role in the photosensitive drum.
addition, the laser printer’s imaging drum is not rotating, there will be no images generated and transmitted on paper. disconnect the printer, remove the toner cartridge, open the lid The notch in the drum to be a sign of non-sensitive parts of re-loading machine. switched for a while, and then remove the check mark is moved, you can determine photosensitive drum is working. If you can not properly supply or laser toner beam is blocked, there will be a blank paper to print the phenomenon. Therefore, we should check whether the run out of toner, ink cartridge into the machine is correct, whether the sealing tape were removed or whether the laser channel blocking properties. Note is sure to check the power off, because the laser beam may damage the operator’s eyes.
2, printing paper for dot matrix printer output black
caused the failure is due to ribbon hair removal, too much on the ink ribbon and print head dirty, poor quality and putting ribbon location so close to such adjustment, repair should be putting the first adjustment position, such as the failure can not be excluded, and then replace the ribbon, cleaning print head, the general failure can be ruled out; for inkjet printers, should focus on checking whether the damaged nozzle, the ink tube is broken, the ink type is normal and so on; for laser printer, mostly due to the corona discharge wire control circuit failure or malfunction, making laser has been launched, resulting in black print output. Therefore, we should check whether the corona discharge wire disconnected, or the existence of high-voltage corona, the laser beam path of the beam detectors are working properly.
3, incomplete or printed characters character is not clear
for inkjet printers, there may be two reasons, to make ink cartridges, printer, or direct sunlight for long time caused the nozzle to plug. The solution is to inject the ink cartridge or renewal, if the cartridge does not run out , it can be concluded that the nozzle plug: Remove the cartridge (not the one for the printer cartridge nozzle needs to remove the nozzle), the nozzle on the warm water soak for a while, be careful not to board some submerged in water, or else. < br> For the dot matrix printer, may have the following reasons: Print ribbon to use for too long; print head a long time without cleaning, too much dirt; print head with needle; print head drive circuitry is defective. The solution is First adjust the print head and print about the spacing between rollers, failure can not be excluded, can new ones ribbon, if still does not work, you need to clean print head. methods are: removal of the print head, the two fixed screws, won print head, a small hook with a needle or remove the print head before and after the inclusion of dirt, are generally long accumulation of ribbon fiber, and then print the back of the head in place to see a few drops of instrumentation needle oil, in order to removal of dirt, do not install a few dozen empty ribbon of paper, and then loaded ribbon, so that the basic problem can be solved, if the print head driver circuit breakage or problem, we can only replace print drive control of the needle or .
4, print writing underweight
for dot matrix printer, causing most of these were the causes of dry ink ribbon and print head needle, putting position adjustment too far, can replace the ribbon and approach to the regulation putter; for inkjet printers, nozzle clogging, ink had dried, the ink type is not correct, lose ink tube into the air, the printer operating temperature is too high will cause the failure to deal with nozzles, ink cartridges for detection maintenance ; for laser printers, the toner when the toner box smaller, developing roller and the toner low-voltage light-sensitive imaging of bad, it will also result in the phenomenon of print writing and underweight. At this point, remove the toner cartridges gently shake If the print was not improved and should replace the toner cartridge or printer toner cartridges regulation under a set of light-sensitive switch, so that the exposure sensitivity and toner match.
5, when the writing side of the print the other side is not clear This phenomenon clearly
generally appear in the dot matrix printer, the ink-jet printers may also appear, but the probability of small, mainly the print head and print roller is not parallel to the rail, resulting in nearly two caused far distance. solution can adjust the print head and print guide roller spacing, so that parallel. Specifically, this: Loosen each print head rail on both sides of the flap, counterclockwise rotation flap gap decreases, and finally to print the guide and print head roller can be adjusted to solve problems in parallel. but to pay attention to when the transfer regulation on the direction, you can gradually adjust to print several times over.
6, printing paper and recurring stains
repeated dirty stylus printer failure was largely due to excessive ink ribbon caused by hair removal or replacement of the ribbon cassette can be ruled out; inkjet printers repeated dirty or lost due to ink cartridge tube Loumo result; poor performance when the nozzle, the ejected ink and ink are not well off while remaining in balance, there will Loumo phenomenon; the laser printer has a certain regularity of such phenomena, as a piece of paper through the printer, the machine transfer of 12 rolls over more than a lap, the largest drum turned 2 or 3 laps, 10 laps feed roller may be turned, when the paper appears equal intervals stains may be dirty or damaged by the roll caused.
7, the print head movement blocked, stopped or in situ shock blew
This was mainly due to a long rail slide the print head can become dry, the print head moves will be blocked, to a certain level will cause the print stop, if not dealt with severely burned when driving circuit. workaround is to print the guide painted a few drops of oil instrument, the print head moves back and forth, Shi Qi uniform distribution. After the reboot, if you have blocked the phenomenon, then driver circuit may be burnt out, need to get the maintenance department of the.
8, the printer does not print printer will not print
cause failure for many reasons, there are printers, and also a computer area. The following were carried out Description:
1. Check whether the printer is online. In most printers on \not light or in a flashing state, the description line is not normal, key check the printer is connected, editor: home network www.shangmen.com printer power switch is turned on, the printer cable is connected correctly and so on. If the online light to normal relations off the printer, and then open, print a test page to see whether it is normal.
2. Check whether the printer has been set as the default printer. Click \small hook, and then the printer set as the default printer. If \is set to pause printing. is in the \pause print \, it indicates a problem with the use of the printing process, focusing on inspection WPS, CCED, Word or other applications, the correct printer is selected, if the application generates a print file, please check the application generating the print output is correct.

BIOS in the printer port should be set to \br> 8. Check your computer for the presence of the virus, if need antivirus software antivirus.
9. Check the printer driver is damaged. can right-click the printer icon, select \; Add Printer \> 9, the printer jams or printer can not take the paper
the most common failure is the cardboard. failure occurs, the operation panel indicator lights up, sends a warning signal to the host. appears that the causes of the There are many, such as paper output path within the debris, rotating parts such as failure of feeding rollers, paper does not feed paper, sensor failure, etc., ruled out failure of the method is very simple, just open the lid, remove the card was paper can, but note that the direction must be taken into the paper, paper, and must not turn any knob the opposite direction.
regular cardboard if we should check the feed channel, clear the output path of the debris, the front paper edge to just above the metal plate. check out the spring rolls are worn or loose, the pressure is not enough, that is not the paper into the machine. the paper roll wear, and sometimes can not be replaced, the available methods for winding rubber bands Emergency . wound rubber band, the increased friction rub paper, can feed back to normal. In addition, the loading tray is not installed properly, the paper of poor quality (too thin, too thick, wet), can also cause jams or paper can not take the fault.
10, the print appears random characters
both dot matrix printer, inkjet printer or laser printer has a print garbled phenomenon, mostly due to print damage or host microcontroller interface circuit damage caused by The actual inspection found damage to the printer interface circuit failure is more common, due to micro power supply interface circuit, once the interface to produce instant high voltage static electric plug, it is easy to breakdown interface chips, usually as long as the replacement interface chip, such failure can be ruled out. In addition, the printer fonts will not load correctly this phenomenon.
further trouble for some printers say what
1, print and preview different general this
situation occur in a text editor, and common, such as Word or WPS2000 so obviously in preview form neat, but print them out to find some fonts overlap. This situation is generally inappropriate due to editing settings fitness into, and its solution is a change of file \In ordinary use the printer is very common in general is largely a hardware failure and related problems encountered in general should be noted that some of the key parts of the printer. we are here to inkjet printers, for example, experience fuzzy color printing products, fonts, the situation is not clear, you can lock in the nozzle failure, the first of the print head for automatic washing machine, without success can be a strong soft absorbent paper, clean the print head near the place *; If the above method still can not resolve them, only to re-install the printer driver has.
three, can not print large files
this case occurred in the laser printer are more likely to print a small file or a normal However, it will crash when printing large files, this problem is software problem, you can view the remaining hard disk space, delete some useless files, or check the amount of memory the printer, whether expansion.
4, choose Print no response after the printer
general when this happens, the system will usually prompt \; poor contact; computer parallel damage, etc.. The solution has the following key:
1, If not start (that is, the power light does not shine), first check the printer’s power cord is properly connected, in the off state re-plug the power cord again, and for an outlet to try to see whether the solution.
2, if you press the power switch the printer to print the normal start, on the BIOS settings, and then take a look into the parallel port settings. general printer ECP mode is used, but some printers do not support ECP mode, then used ECP + EPP, or \Turn off the computer, the printer cable re-inserted about 2 pull down, careful not to electric plug. fruit also can not resolve the problem, try another printer cable, or alternative method.
5, print is not completely
If you encounter this problem, you can say for sure that is caused by a software failure, you can change the printer port in the system settings, and select \driver change the driver r r show all devices \In fact, the printer’s failure to resolve the most important thing is to judge, as long as the reason to find fault, you can approach by hardware or software methods of repair. Of course, when people actually use the printer will encounter other problems, so this requires you to master printer repair techniques

Common Faults and laser printer solutions
laser printer is a computer system, external devices, its role is to deal with the results of the computer to a particular form of that out. laser printer because of its beautiful print quality is being more widely used. However, such use often occurs, like failure, affect the kind of quality. The following account of the problems I encountered and solutions, for reference.
1, a laser printer warm more than 2min or setting is not strong, the text off.
First, consider the interior temperature has reached above 20 ℃;
second is to check whether the connection is bad or the failure of the thermistor;
third is to see whether the voltage is 220V;
4 is to look at the paper, toner too damp.
2, or cardboard.
First, check whether the appropriate paper size, paper too thick, too thin, damp or curled paper, the phenomenon will have a paper jam;
2 is not coated paper for laser printers; < br> 3 is to check whether the laser printer separation claw wear need to be replaced.
3, such as the printed pattern on a partial or all of the words is unclear, uneven toner concentration of the phenomena.
reason for this failure is The toner cartridge insufficient, needed to add.
4, in the printed pattern or black spots appear on the underworld, and after changing paper in the same position.
the cause of the malfunction is OPC drum with injury.
5, if the printed pattern on the horizontal stripes appeared, but still in the same location after changing paper appears
6, if the printed pattern of vertical stripes appear, for paper is still the same after position there is a box for the bunker on the magnetic roller is damaged, to be replaced.
7, in the printed pattern, the characters are serrated line of text appears missing document has been zoned off, indicating hexagonal rotating mirror or Ft objective, there need to clean the dust (this problem for a professional technical staff).
8, replace the toner need attention:
first need to send and receive bunker bunker to clean up the remainder of powder; < br> The second is the toner, the toner inside the bunker to get parallel to shake hands the number of ring gear clockwise rotation, so that the toner evenly attached to the magnetic roller to ensure uniform toner.
9 If, after replacing toner, ink text appears uneven or powder leakage phenomenon, after the failure to print a few, or not resolved, then we must first consider whether the wet ink, then consider sending the toner is too full bunker .
10, a laser printer in the hair-like process, if the host displays a \solution.
11, if the laser printer out of self-test pattern is an all black, no self-test line. host display appears \Image maintenance
in the printed page often occur without the first part of the image, then print out the original part of the first half, but the images normal and no deformation.
failure phenomenon that is a bit bad for the paper caused under normal circumstances, when the paper is rubbed between the upper and lower rollers of the bit when the roll is not in the rotation of the bit state, but a brief stop in the state, when the controller receives the right track in the scanner position sensor the output of the digital signal, on the bit roll rotation, rotation of the photosensitive paper Jibei sent to the drum, the paper and send the speed and drum rotation speed equal to, paper and photosensitive drum on the front of the front image alignment, and then After transfer, fusing, or get a print the same page with the manuscript.
when printing paper is sent in advance of the roller bit, if he sent the paper speed and line speed of photosensitive drum are equal, then the printed page is the first half of the Department of blank, no image, with the latter part is the original manuscript of the first half, and the image normal, otherwise the image is deformed.
seen from the above, the reason is to place sensors or controllers have problems, check the track next to the scanner rack sensor. found a sensor problem, causing on the bit roll in advance feed, replace the sensor after the test print, troubleshooting.
scanner for the paper to advance to one side can not return to HP laser printers in situ, In the continuous printing process, the scanner suddenly move to the side of the printer for the paper can not be returned to in situ, the printer issue \Back to poor sensor performance.
(2) poor controller performance.
(3) return sensing controller connection problem.
(4) scanner driver system of mechanical malfunction.
under fault phenomenon, is in continuous print in the sudden, and accompanied by abnormal sound, so suspect the mechanical part of the scanner drive system faulty.
open the printer, move the scanner back and forth by hand, are moving very difficult, under normal circumstances mobile scanner is a very light hand, and this, to push back the scanner in situ, boot observation panel display normal, when the main motor starts spinning, the scanner has started to move forward. exposure light does not shine, mobile scanner the process is not unusual to hear \Spindle motor starts spinning, if the scanner in place, then stand still; If the scanner is not in situ, should be immediately returned to in situ.
open the printer, move back and forth by hand to further check scanner, found that all of the chain were followed by rotation, but under normal circumstances, move the scanner frame, only the rope around a drum scanner driver rotation, the chain is not rotating, it is apparent that drum problems with the drive sprocket, they are scanner drive parts, chain wheel is located inside the drum, under the action of the clutch to drive shaft rotating drive drum rotation. through this part of the demolition, it was discovered loaded ball bearing wheel center has been badly worn, the drive shaft was until it has a slot to be killed sprocket with the drive shaft so that when the wheel starts to rotate, the drive shaft is driven, with the drum rotating, drive axle of a drum, \forward and can not return the fault.
failure to completely remove, replace a new clutch, the other components will be installed by a good test machine in situ, working back to normal troubleshooting.
send a print job from the software without the printer reaction
When a laser printer to send print job from the software, if the printer does not respond, its causes and check the rule as follows:
(1) power cord and the printer is not connected or power does not check the power supply and power cable, so connect securely.
(2) The printer may stop working, dormant software recovery, wake up the printer.
(3) the connection between the printer and computer cables are not connected to the printer and the computer re-between Connection cable connections are secure.
(4) connection cable defective: the cable can be tested on a normal machine, verify whether the defects, if proven correct defects, should be replaced with new cable.
(5 ) software, choose the wrong printer check printer software, select the menu to see if the correct printer selected.
(6) failed to configure the correct printer port, check the software configuration of the menu, ensuring access to the correct printer port, If the computer used is not a parallel port, to be sure that the printer cable is connected in the correct port.
(7) printer connected to the converter is not set correctly, check the converter settings, the printer can be connected directly to the computer, it Verifiable converter has problems.
(8) Repair printer printer failure should be.
full-page print page pale
a laser printer, print out full-page page pale. cause reasons of this failure phenomenon:
(1) Toner toner box is no longer enough: check the amount of toner the toner box, if it has almost run out of toner cartridges should be replaced or added toner.
(2) Toner sufficient, but adjust the concentration of too short: to re-adjust the toner concentration, it shades fit.
(3) of the photosensitive drum strength is not enough: to re-adjust Photographic strength, so that sensitive enough. < br> (4) adverse working conditions photosensitive drum heater: Check photosensitive drum heater working conditions, ensure that its work well.
(5) high voltage electrode wire leakage current, low charging voltage: Check the availability of high-voltage wire electrode and the fixation phase phenomena such as leakage, if it should be insulated.
(6) Transfer corona installation location has changed: Check the transfer corona installation location is changed, if it has changed position adjustment should be good ensure that the transfer voltage is sufficient.
part in the output of paper to print large sheet of cardboard
Whether or small piece of paper, some are in the output of paper jams. on normal paper carton rub, rub a piece of paper only, and the next paper carton is more than rubbing.
open the machine for inspection, you can see parts of a single sheet of paper passed the two jammed feeding paper rolls but no longer advance, and the next box in the folder before feeding parts more sheets of paper rolls of paper stuck to the Department, and stop there. explain feeding components jammed between rollers and the feeding roller gap, not jammed roll paper feeding roller and the friction between the lead paper at a standstill, because this phenomenon is the result of long jams, resulting in feeding components jammed shelves spring roll deformation and lose their elasticity, causing paper jam jam roll enough power, paper and transportation can not generate friction between the paper roll, paper roll while able to pass the jam, but can not move.
hand-jammed roller frame, has been deformed, will be jammed roller frame unloaded, after the replacement of a new spring , complex installation, testing machine to print, working to restore normal troubleshooting.
stylus printer Fault and Maintenance of a few
inkjet and laser printer prices decline gradually are affordable units and individuals are using the equipment . but stylus printer supplies cheaper, lower operating costs and, in some special printing requirements, such as multi-layer printed waxed paper and pressure sensitive papers, the printer can not have non-use of needle. Stylus printer during use, because a variety of reasons, often some failures, some failures are not pay attention to the use of the process caused some glitches can be solved yourself.
question one: Turn the printer power switch, printer, \; ring,
printer \will be prone to the failure. because of the dust accumulated on the print head movement axis, and the oil mixed together, piled up, leading to higher resistance, when you open the printer power switch, drag the print head to move the motor over. ..

instance, HP 6L laser printer does not print
Failure phenomenon: HP 6L laser printer connected to power its operations after the panel ERROR (error), DATA (data) and READY (ready), after the three lights were lit, and the remaining yellow ERROR (error) indicator lights, printer No response.
Analysis: For the HP 6L laser printer, the boot after the operating panel ERROR (error) indicator light, said: Printer out of paper, cover did not cover, not equipped with drum or a photosensitive drum assembly components in place and the printer is not installed There are cardboard. according to the following steps to check and remove:
Maintenance and troubleshooting process: First, unplug the power cord to the printer, view the back of the printer tray is installed in the printing paper in place, the so-called printing paper in place is to ensure that the front will be located in the bottom of the tray into the paper sensor to suppress by check printing paper is installed correctly; and then open the printer lid and check whether the printer cover closed when the pressure sensor to the cover in place, and the printer drum is in place to install the components, these parts after inspection found no problems; Next, open the printer lid and remove the cover behind the printer, check whether the printer jams, tweezers and gently flip the location of the printer out of paper out of paper detection sensors, to observe the sensor for damage, loss or stuck phenomenon, the results were normal; Finally, remove the back of the printer cover, then check into the paper into the paper sensor two areas for damage or failure to place the phenomenon. The inspection found that a sensor (the sensor Paper round of the components in rubbing below) can not be reset, remove the sensor, it was discovered leveraged plastic deformation sensor arm was stuck by the replacement of the sensor after troubleshooting.
Troubleshooting experience: HP 6L laser printer feed zone there are two sensors detect the paper: the first one in the bottom tray, used to detect whether the printer to print on paper; the second is the paper delivery sensor for detecting printer transmission systems are in working paper. These two sensors are used as check paper photosensitive interrupter sensor, by a plastic lever-type sensor arm and the combination of photosensitive breaker. When the back of the printer tray with paper, printing paper by rubbing roller transmission sent to the sensor position paper, printing paper, press and hold the position of Office of the sensing arm of the upper part of the role of force in the lever, the sensor arm in the lower part did give away photosensitive breaker, breaker photosensitive is through the state, the main control circuit in the printing paper in place to detect the signal, they start to count until the printer out of paper sensor detects areas of paper so far, if within the prescribed time, printing paper does not reach the paper sensor location , the main control circuit according to the paper stored in memory there is no information, identify the printer is jammed, immediately interrupt the main motor running the program, the operation panel on the light will light cardboard. in this case because the photosensitive paper delivery sensor breaker has been in through the state, the main control circuit from the start of work on counting, the counting time and the machine does not match the data stored in memory, determine the printer to jam.
Instance, HP 6L laser printer does not print
Failure phenomenon: HP 6L laser printer connected to power after a while the operation panel ERROR (error), DATA (data) and READY (ready) all three lights on, the printer did not respond.
Analysis: HP 6L turned on the operation panel ERROR (error), DATA (data) and READY (ready) all the three indicator light indicates that the printer hardware error that is: the printer’s fuser component failure or laser heaters component failure. to the printer operator panel on all three indicators light, click the button panel, if the button is pressed DATA (data) lamp, the light is a snapshot release later components heater failure:
Maintenance and troubleshooting process: First, remove the superstructure of the printer; unplug the printer frame to the right of fuser heater plug, plug with a multimeter measuring the resistance value, the measured resistance value of the terminal is about 120 Euro, no problem; Then remove the printer cover, then open the laser components of the superstructure, hand laser scanning mirror rotating central shaft (be careful not to run into mirror), feel the jam clear sense of the scanning motor or control and drive circuit is faulty, with a new scanning motor drive board replacement printer troubleshooting.
Troubleshooting experience: HP 6L laser printer scanner uses a motor-driven scanning mirror. It is a four piece with a positive side as mirror, by the motor drive for high-speed rotating polygonal mirror, which is a 4 mirror and motor assembly as one of the combination. When the laser beam scanning mirror on the four sides, with the high-speed rotating scan mirror scanning reflected light into a line, when the scanning mirror to the next mirror, the reflected light is then left to right-scan line. so scanning mirror is rotated scan line 4. in this case the scan motor jam occurs, causing motor can not operate normally, the beam detection circuit detected the normal scan signal, main control circuit board will determine the printer hardware appears failure to terminate the current procedure, the operation of all indicator light panel.
Three examples, HP 6L laser printer print quality is poor
Failure phenomenon: HP 6L laser printer self-test print, the image background has serious bottom ash and print writing and lighter.
Analysis: There is a print writing is light and heavier bottom ash may be the reason: photosensitive drum in the toner component is close to running out, the primary corona discharge electrode may have been disconnected, and poor contact between the photosensitive drum assembly or no discharge pressure. added to the photosensitive drum roll on the imaging component of the DC voltage is very low, causing the toner is not polarized or polarization is very weak, so the toner can not be properly transferred to the photosensitive drum. and the photosensitive drum pieces of the middle of the photosensitive drum surface film of the optical characteristics of aging, the deterioration of the surface potential.
Maintenance and troubleshooting process: first replace the imaging drum component or components to re-open the powder charge. Then remove the photosensitive drum components, check availability contact the contact component dirt or oxidation, the flexibility of the machine contacts is good, then remove the printer’s floor, check the main control circuit board, there are three high-voltage contact is not toner pollution. then check the main control circuit board DC voltage is normal (can replace a master conditional circuit board to try). The photosensitive drum assembly for the examination revealed the ground contact deformation (right side in the printer, there is a component of the ground the imaging drum’s bottom shell client and the printer connected shrapnel contact), replace the touch point and troubleshooting.
Troubleshooting experience: As the photosensitive drum assembly of ground contact deformation makes the drum component of the ground point connection problem, leading to the primary corona discharge circuit and no failure.
Four examples, HP 6L laser printer to print is not clear
Failure phenomenon: HP 6L laser printer to print self-test print characters clear, but the details do not appear to print fine print Shique clear failure.
Analysis: laser printer has a print is not clear and more common phenomenon, caused by reason of such failure generally: photosensitive drum or toner box of the toner component deficiencies; print media does not meet the specifications required by the printer, such as print media moist or too rough dielectric surface; print laser toner concentration setting improper or failure.
Maintenance and troubleshooting process: First, check and remove the imaging drum components or print media’s fault: Gently shake the photosensitive drum components, so that re-distribution of the toner or replace the imaging drum; then required to re-select the print media; and software or printer driver to adjust the toner density setting. The results have not been able to troubleshoot. Thus, the laser is more likely to fail, according to the following steps to check and remove Laser component failure:
Open the printer cover, remove the laser components, laser components and then remove the metal cover, were examined with a scanning mirror, lenses, mirror, on whether the toner, dust, and if so, with cotton wool dipped in ethanol Gently wipe. Then remove the laser head components (laser head and laser drive circuit board), check the laser focusing lens above the surface of the coating is aging, with or without dust or spots, if dust or spots then gently with cotton wool dipped in absolute alcohol wipe, if the coating should be to replace the aging lens. After the inspection he discovered that the laser focusing lens above the surface of the coating aging, replacement of a new focusing lens and adjust the distance ( The laser head and laser focusing lens had a certain distance, adjust the print will appear improper fuzzy fault), the printer troubleshooting.
Troubleshooting experience: In order to broaden the laser beam modulation frequency, laser equipped with a laser hair out can be focused laser beam focusing lens. When the printer’s ambient temperature and humidity changes, making the lens on the optical coating are aging, or toner and dust pollution in the lens surface, will affect the laser beam transmission, the results appear to print resolution of the printer down the fault.
Five examples, Hewlett-Packard LaserJet 1010 laser printer can not print
Failure phenomenon: HP LaserJet 1010 laser printer for network sharing printers in use, whether to print from the network or from the local print, occasionally can print after 12, you can not print, and sometimes one can not print.
? Font color = \Maintenance and troubleshooting process: remove the original after reinstalling the printer driver, print first two no problem, then still error when printing, change the print signal line does not solve the problem. View the print settings have not found the problem. Finally open the printer the lid, took out the printer cartridge was found inside the drain a lot of toner, cleaned and then print, all normal.
Troubleshooting experience: This failure is due to toner is conductive, the leakage of the toner when printing a single component may cause the printer malfunction caused a temporary short circuit. Therefore, we in Canada when the powder into the cartridge, one must ensure that the selenium drum does not leak powder, 2 to promptly remove the printer toner leakage inside the machine, if the leakage of toner too much removed in time, not only cause the printer does not print, and may even damage the printer board.
Examples of six, HP 1100 laser printer to print no characters
Failure phenomena: HP 1100 laser printer, the implementation of print command to print, but print no characters.
Analysis: This fault is generally not as photosensitive drums rotate, the toner cartridge has run out of printer ink cartridge simply does not mount the machine, sealing tape has not taken off, not open circuit transmission line corona discharge causes. < br />
Maintenance and troubleshooting process: First check the drum part is to open the printer cover, pull out the cartridge to the outer cover, toner cartridges in the printer’s front cover to remove the toner cartridges, toner cartridges have to open the lid, in the open cartridge cover will feel a certain resistance, open the cartridge cover, you can bring cartridge and remove it. inspection found that the sealing tape has been removed, gently shake the cartridge, there are many Mexican feel inside powder, there is no issue of toner used, re-installed photosensitive drum, the boot print observation, drum rotation normal.
Then check some of corona discharge, corona discharge part of the main reasons for high voltage circuit fault occurs the fault and some faults corona.
High-voltage circuit fault occurs there are two main aspects of performance and maintenance:
1. High-voltage circuit fault itself. Such as the oscillation circuit module is damaged, high-voltage pulse transformer high-voltage winding open circuit (high voltage winding diameter smaller, easier to break). To open the machine with a multimeter to directly measure high-pressure high-voltage pulse transformer winding DC resistance and did not open.
2. Contact connection problem. Long use, the printer toner makes high-voltage generator of high voltage output contact with photosensitive drum assembly on the bias point of contact with the poor contact imaging; high voltage generator circuit board drum ground contacts and ground point on the photosensitive drum poor contact, resulting in printing the page all white or all black phenomenon. check is to open the machine, remove the photosensitive drum components, respectively, contact the relevant check whether the printer or the toner dirt , photosensitive drum assembly on whether contact dirt or toner.
Corona Corona main reasons some fault circuit transmission line can not discharge, corona some quite dirty, aging and other reasons. Check corona circuit line was not found with a little isopropyl alcohol, stained with cotton balls clean corona wire , boot prints, failure has not ruled out.
Again disassemble carefully examined and found close to the photosensitive drum of the laser beam channel is paper jammed, causing the laser beam can not be irradiated to the photosensitive drum. After removal of waste paper, troubleshooting.
Seven examples, Hewlett-Packard HP 1100 laser printer to print the script appears white stripes
Failure phenomenon: Print a vertical white stripe script
Analysis: The main reason causing this failure the following two aspects of laser scanning systems are dirt, dirt encountered when the laser is absorbed, can not reach photosensitive drum, thereby causing the occurrence of failure; second turn corona wire-bound printed below the print paper channels will attract dust and scraps of paper, some part of the corona parts become dirty or blocked, thereby preventing transfer of toner from the photosensitive drum to the print paper, resulting in the occurrence of failure.
Maintenance and troubleshooting process: First check the laser scanning system, including whether there is debris blocking access, and clean all mirrors on the dirt, and then boot print, fault still. Then check the transfer corona wire, and found some scraps of paper and toner like dirt, clean with a clean cotton ball after the transfer corona wire, troubleshooting.
Eight instances, Hewlett-Packard HP 1100 laser printer to print issued with bottom ash
Failure phenomenon: Print issued the side of the bottom ash appears.
Analysis: This failure usually is due to uneven distribution of toner inside the cartridge, waste bunker is full of aging or damaged cartridge, laser scanning system failures and other causes.
Maintenance and troubleshooting process: First, replacement of the photosensitive drum, before and after the replacement of its left and right front sway back and forth to drum toner distribution, re-installed, the boot print, did not rule out failure. Then check the laser scanning system, found photosensitive drum position of a mirror above the drift, the mirror position is adjusted after the boot print, troubleshooting.
Nine examples, Hewlett-Packard HP 1100 laser printer to print draft writing underweight
Failure phenomenon: the printed manuscript writing underweight.
Analysis: This fault is usually low due to imaging roller imaging bias was polarized charged ink powder, toner toner box is too small, reducing the sensitivity of photosensitive drum or toner due to poor photographic results.

Maintenance and troubleshooting process: first remove the cartridge, shaking slightly, so that uniform distribution of the remaining toner, and then re-put back in the printer, printing has not been significantly improved, indicating that the toner is not too few, then replace a new cartridge, failure has not ruled out, toner cartridges also cause fatigue or aging can basically rule out the possibility. clean transfer charge corona, because the toner, dust and pollution will make the various scraps of paper corona voltage drop, direct affect print quality, clean the malfunction has not ruled out. and through the software or printer driver settings to re-adjust the toner density, closed economy, appropriate to reduce the resolution of the printer software such as measures to improve the printing results, the results did not succeed.
Re-examination revealed erase light bulb has aged, its brightness is not enough, this erasure is the role of light sensitive surface bulging even bring? 100V of the charge erase lamp bulb replacement after troubleshooting.
Examples 10, HP 2100 laser printer does not print

Whether it is compatible device or card machines, in the course of the phenomenon will appear inexplicably crash. Death is a common fault phenomena, but also a not easy to solve difficult cases. Especially when the computer crashed after , then we can not use the software or tools to test the machine, repair them is often a headache.
1. crashes generally showed:
1) after power up without the host did not respond, the power indicator does not light the fan does not turn;
2) the system does not start during startup screen suddenly stagnant;
3) during the startup process displays a black screen or display a black screen during use;
4) image \solidification \break;
regular blue screen.
9) often report an error or memory overflow.
2. fault performance
Specifically, the crash can be classified into two cases of hardware and software. :
1. Hardware
hardware caused crashes often are: mains voltage instability, the host power supply output voltage is too low or too high, too high temperature within the chassis, memory, temperature overheating, CPU temperature is too high, overclocking , interference, peripheral to their own fault, poor contact card, the host and the peripheral data lines connected to poor contact, etc..
(1) electricity voltage instability
computer voltage range of typically 180V-240V room, when the voltage falls below 180V, the switching power supply output voltage is too low or protection, then reboot the host is easy or automatic shutdown; when the voltage higher than 240V, the electricity power supply input voltage exceeds the allowable scope of the host, but the circuit The discrete components, then the power may not have protection, then the secondary power output may be high, the same phenomenon can also cause crashes.
(2) the host power supply is not completely damaged
when the host power supply inside circuit is damaged, then the voltage output current output may be biased or inadequate, resulting in effective loading rate is less than this time will also have the phenomenon of Death. current mainframe computer switching power supply used in most of the use or similar TL494 PWM control chip, compared LM339 or LM393 devices commonly used to control whether to send the switch determine the host machine signal. When the chip is faulty, there will be short we lead after the green line and black line (some books require the use of 100O resistor, in fact, not necessary, the internal power supply circuit has been connected in series about a 2K resistor, even if the short circuit current, but also a few mA), power supply fan working, multimeter test voltage outputs can be normal. But the access circuit, the power can not be normal work. This is mainly damaged the chip, the voltage sample is wrong, not with a heavy load caused by Jun only by exchanging with the model Xinpian can.
I met Yi Ci, a no-name power supply, use of a year and a half so, the host often crash or not start, final inspection switching power supply, +5 V output was found as high as 5.86V, while the +12 V is only 9.9V, the power supply like this do not crash when pigs fly, okay, not the motherboard burned.
(3) the heat within the chassis of dust too bad
chassis will cause the system to hang. dust is the enemy of the computer, too much dust attached to the CPU, chipset, fan cooling the surface of these components will lead to poor or poor contact; same printed circuit board of the dust in the humid environment often leads to short-circuit. In both cases the phenomenon may lead to crashes. This situation is common in some old computers in place to open a year or two later when nothing happened after a boot or \accurate, so a boot CPU temperature is usually around 50, far higher than the detection SOCKET 370 CPU temperature (about 30). However, because PIVCPU the heat capacity, the CPU fan must be selected according to the type to select the CPU the corresponding CPU fan, do not let the small horse-drawn carts, otherwise crashes constantly.
solution: we can use brush to sweep the dust, and then hair dryer (cold air file) to the gray card sharp clean up.
Note: Do not brush and cotton swabs of wool, cotton remain in circuit boards and components become a new source on reset. If we can clean up once a year within the host and display the dust, our love machine would not have no reason to strike up.
(4) DIY overclocking
many friends like to improve your computer by overclocking performance, so you can spend less money and more things. but there are big problems: light is caused crash, may cause heavy CPU, memory, hard drive completely scrapped.
overclocking once I have the experience, the 66 super hard on the motherboard FSB FSB 83, just started working well, when I I was a small trial for their complacent when the chopper, two days later, suddenly in the running, the system can not find the hard drive tips. At first I did not care, then more and more frequently, in the end could not find any hard drive in the CMOS . especially now P4CPU increasing its integration, and some have used 0.09-micron line, when we use overclocking, it is likely to cause excessive CPU within the electronic attenuation, the final link line completely broken, causing CPU scrapped.
(5) error
motherboard jumper FSB and multiplier, some motherboard using the line or pull code switch, CPU or memory, choose to use the power supply voltage jumper settings, then we have to follow the instructions to set the corresponding main CPU frequency multiplier parameters and the corresponding use of voltage. If the set does not cause the CPU overclocking potential, set the parameters too high, you may enter the system on a black screen or a crash. Sometimes we in the CMOS jumper after discharge did not jump back to the original position, then it will start at power-black does not start. Some motherboards support both SD and DDR 2 kinds of memory, attention selection jumper on the motherboard are +2.5 V and +3.3 V are two voltage settings. particularly CPU The core voltage setting a not an error, or easily cause CPU scrapped.
(6) peripheral damage to the internal circuit when the peripheral
such as displays, printers, M damage the internal circuitry, and then connected with the host would short-circuit the corresponding port, then when the host can not power up self-test or cause power protection. Some cutting plotter, the editor earlier in the host after power up, then the host can not start after power up.
(7) and the peripheral data lines connected to poor contact.
peripheral and host a loose cable connection, they may cause the data during transmission interruption or error, it will also cause erratic crash the machine.
(8) hardware, poor quality or counterfeit goods, parallel imports.
hardware quality, but hard, work long hours or work in the ambient temperature is too high or too low, there will hang phenomenon. In particular, some computer REMARK products installed in your computer troubles, it is best to check to check also can not find the problem, the best time to consider not buying the goods of the JS.
some time ago, many Barracuda 40G hard drive, buy a house less than a week, it appears bad sectors. and then FORMAT after the normal, but over time the fault occurs again, then more and more serious, and sometimes inexplicably lose the data.
(9) accidental damage during maintenance
our body does not discharge static electricity or lightning current to pass through the protection of the power and telephone lines into the host MODEM, damaged power supply, motherboard, MODEM, and various internal and external equipment . accidental damage to the surface after the components are sometimes not obvious burn, crack trace, then only through the exchange, swap testing the various components of the host to determine good or bad.
(10) interference
are now at home There are many household appliances, especially of inverter air conditioner, washing machine, cooker, etc., these appliances will work to the large amount of electromagnetic radiation in the air, if the computer is nearby, it is also possible the phenomenon of unexplained crashes or blue screen. Then We’d better computer for a place to try.
(11) damaged or incompatible memory
when bad blocks occur when the internal memory or the motherboard’s compatibility with the bad, will always appear: Registry Error , memory error, blue screen, system resources, then hang.
now host of features more convenient, such as a keyboard boot, boot password, STR and other work. But the more features, the likelihood of its failure greater. in particular STR function, the function when the machine is open, we choose to sleep, then put the current system settings stored in memory, then the rest of Dian Lu closed, only the work and memory Vice Dianyuan related circuit. during sleep, memory constantly refresh the content of which is not lost. But if in summer, because each memory power probably around 20W, long sleep, it will cause excessive heat build-up, Powder does not go out, and finally burned to the host power supply or memory.
2. Software
software failure caused a lot of crashes, such as virus, driver installation errors, the driver or other software conflicts with the system, CMOS settings wrong CONFIG.SYS or AUTOEXEC.BAT configured incorrectly, WIN.INI or SYSTEM.INI file to load the file is missing or damaged, loaded too much, too little system resources such as surplus.
(1) virus
generally showed the normal machinery of the original first run, a sudden run on slow, crashes frequently occur phenomenon. then we must first of all with the latest antivirus software, virus, to determine whether the machine has been infected with a virus. Computer viruses are now emerging, modes of transmission tend to spread through the network, so we in the Internet, be sure to install the network anti-virus software, and some commonly used ports are not open to close.
(2) driver installation error < br> hardware error or hardware drivers installed its own driver BUG, the phenomenon can also cause crashes, then need to check the installed drivers for the hardware if the hardware model or models to match the core chip. If you can, to download the latest drivers for the hardware.
(3) CMOS setting error
CMOS contents, such as CPU frequency, multiplier, memory refresh time, L1, L2 is open, ECC check or even Check ,15-16M, etc., the above, setting error, the host will feel significantly slower processing speed, and finally crashed.
When the CMOS settings in the \function is open, we install the software process WIN9X crash will result in the phenomenon, because then the system prevents a program guide to the main zone and zone C BOOT disk write commands.
CMOS parameters due to frequent changes, or viruses CMOS parameters on the damage, often leading to confusion and difficult to restore CMOS parameters. can be used on the CMOS discharge method and using the system BIOS settings to re-set the CMOS default parameters. CMOS to discharge, refer to the motherboard manual for. Zhong based CMOS parameters After the virus must also be on the hard disk can be whichever
on the CMOS default settings, such as \
if the software crashes during the installation or after you install the software after a crash on reboot, the system is generally installed in some configuration and software do not match. then you can try on the CONFIG.SYS and AUTOEXEC . BAT in the driver settings related to modifications.
of the CONFIG.SYS and AUTOEXEC.BAT can also press F5 to skip the startup system configuration file or click F8 to step through CONFIG.SYS and AUTOEXEC.BAT select the option to check that a driver or load documents, in particular, EMM386 on EMS, XMS configuration, we may use this to determine the causes;
some hardware drivers and memory-resident programs you can do not load their way to avoid conflict.
for WIN9X operating system no longer needs the support of the above two documents can normally start the system, these two documents is mainly to retain the original DOS program support and compatibility.
(5) WIN.INI and SYSTEM.INI file to load the file is missing or damaged.
if the WIN.INI and SYSTEM.INI files that need to load the damaged or lost in the system boot process Only time will arise in the blinking cursor, keyboard, mouse, did not respond. but most of the tips there is a certain file can not be found. then we can suggest to retrieve the file or files in WIN and SYSTEM in the appropriate option to delete.
If suddenly there is a system can not boot after boot, then we can use SCANREG / RESTORE command to restore the registry to try one day.
(6) software has conflict or not compatible with the operating system’s applicability
more convenient, its procedures and directives are increasingly large, running different software is not compatible There are some places do not. Sometimes the initial version of the anti-virus software there may be in the design of small BUG, it will appear when the user installed the host can not shutdown, system start slow, blue screen of death issues. At this time we only put off or uninstall the software on it. the criterion is that if the installation of a software system is working properly, and when installing a software system is not normal, then the problem is definitely caused by the software.
(7) loaded too much or too little system resources
start if the host configuration is too low or too large applications, it will also produce the phenomenon of Death. Then in My Computer properties, select the \twice as much physical memory or more. address the main method or under the machine’s configuration, select the appropriate application software.
(8) network problems
Sometimes the network can also cause crashes abnormal phenomenon. now popular The Lianzhong, Legend and other online games, if the network is not normal in the course of communication with the server will also have crash phenomenon. Some of the performance of crash course in the Internet, and some showed dropped after the crash.
3. solve Methods
computer failure to meet the basic principles: first, after the hard-soft, after the first addition, the first from the main post, the smallest system, replacing one by one.
4. example
(1) a host Lenovo PII400 In Rising antivirus software installed, start slow. open an application, such as the WPS2000, had to spend 30 minutes. careful testing, not only open the application software for a long time to print a document using the printer, print an A4 paper, would take nearly 10 minutes. analysis of the situation before and after the fault occurs, and finally uninstall the antivirus software Rising, the system returned to normal.
**** new listings this year, antivirus software 2003 instability still exist and incompatibilities, often blue screen after installation or freezes.
we install anti-virus software, best software installation intact, and finally re-installed anti-virus software to minimize incompatibilities or conflicts arise .
(2) a PIII800 host, a small compact chassis, 7-8 months each year, often a sudden shutdown, then boot invalid. have to unplug and then plug in a few seconds after the boot outside to start. This failure is mainly because the chassis is small, narrow interior space, combined with the use of more than a year later, excessive dust, poor air flow, leading motherboard, CPU, power supply heat dispersion does not go out, the final result in power protection or Death . Finally open the case, after the dust for the CPU and power supply troubleshooting.
(3) a CII566 host, just a good machine installed in a computer company, one into the customer’s office, not take half an hour on the Blue Screen of Death . this problem to the customer from the company’s office several times and from, are normal in the company, one to the client’s office in the crash. the last inspection found that the top is a computer at work the air conditioning. Finally the computer is removed After a certain distance air conditioning, troubleshooting.
(4) a PIV2.0 machine, the customer just bought a home not two days, three hours of sleep after use, regardless of how the keyboard, the mouse can not wake up. This the problem is that the user inadvertently CMOS settings STR function open (set to S3), and then use the sleep, leading to power supply overheating. Finally replace the power troubleshooting.
(5) a P166G brain, the installation End RealPLay, the system prompted reboot, the blue and white when there is no response after a longer. This issue may be 166MMX software installed on the machine and RealPLay software conflict or a lack of RealPLay software required documents, resulting in crashes when you start phenomenon. Finally enter the security model, the RealPLay uninstall, you can start properly.
Blue Screen of Death crash Imperative why it
operator vexing issues, often to work the WTO. Death to the show more for the blue screen, can not start the system, the screen \not from reason never hardware and software aspects. Haohao De machines have been running frequently to put a blue now face, people uncomfortable. This brief blue screen of death caused a number of common causes and solutions.
1 , have a hardware failure caused the crash
1. computer overheated loss: monitor, power supply and CPU heat in the work of a very large, so good ventilation is very important, will result in overheating if the display color, image distortion or reduced display life. long working hours can lead to poor power supply or monitor heat caused by computer crashes, may wish to price a high-performance CPU cooler.
2. Mobile inappropriate: the computer move the vibration process under great device inside the machine will often loose, leading to poor contact caused by computer crashes. Therefore, when the mobile computer should be avoided shock.
3. dust wash: the machine components if excessive dust contamination, such as the head, resulting in time write error, a serious cause computer crashes or damage to components, so to keep the air clean, if necessary to remove the computer too much dust.
4. device does not match: If the motherboard and the CPU does not match the frequency is too high and too low can cause frequent crashes. At this time, the situation can change according to the appropriate hardware.
5. hardware and software are not compatible: If running Photoshop, AutoCAD 3D animation, graphic design software, effects on different hardware devices will vary and may cause crashes. We can choose according to the actual situation of the corresponding hardware or software.
6. memory failure: main memory loose, Weld or memory due to the core quality. under the circumstances of exclusion memory access fault, if the memory should be replaced by quality problems.
7. hard disk failure: the main hard disk aging or due to improper use bad sectors, bad sectors. so easily occur in the operation of the machine crashes. less serious, can be ruled out with special tools, the more serious can only replace the hard drive of.
8.CPU overclocking: Overclocking improved CPU, the same time, its performance becomes unstable. The reason CPU in the memory (RAM) access data faster than the speed of the already exchange data memory and hard disk speed, overclocking make it more prominent conflict, exacerbated in memory or virtual memory can not find the required data in the case, it appears \device interrupt, DMA or port conflict, then, may lead to the driver an exception, so that crash. The solution: a \adjustment, the general can be solved. For an exception in driver error condition, you can modify the registry. Select \\0.5-1% in hard drive capacity. so it should be put on the largest possible memory capacity.
11. using inferior components: a small number of unscrupulous traders in a customer assembly compatible, the use of poor quality cards, memory, Some even sell counterfeit REMAEK off the motherboard and CPU, memory, this machine is very unstable in the run-time, inevitable crash occurred. Therefore, users should purchase their own eyes brightened, preferably with a knowledgeable staff , and using some new tools (such as HWINFO, NORTON, etc.) test the computer for a long time continuous test machine (such as 72 hours), and the warranty for as long as possible time.
Second, the software causes crashes < br> 1. HIV infection: the virus makes the computer’s efficiency declined sharply, causing frequent crashes. At this point, we need to use antivirus software, such as KV3000, Kingsoft Internet Security, Rising, etc. to conduct a comprehensive virus scanning, anti-virus, and do so regularly update anti-virus software.
2.CMOS set incorrectly: the fault is common, such as hard disk parameter settings, mode settings, memory parameters set incorrectly causing the computer can not start. if the non-ECC memory function is set to ECC feature, which will cause crashes due to memory errors.
3. delete system files error (or error): As the need for Windows 9X start Command.com, Lo.sys, Msdos.sys and Drvspace.bn four documents, if These files have been damaged or accidentally deleted, even in the CMOS settings are correct in a variety of hardware did not help. Workaround: use the same version of the operating system boot disk to start the computer, and then type SYS C: both.
4. initialization files to find damage: Since Windows 9X start to read System.ini, Win.ini, and registry file, if it exists Config.sys, Autoexec.bat file of course read. as long as there is an error message of these documents Death can occur. In particular, System.ini, Win.ini, User.dat,
System.dat these four documents is particularly important.
5. dynamic-link library files (DLL) is missing: in Windows operating system There is also a class of documents is also important, and this is the extension DLL The dynamic link library files, speaking from the nature of these files are shared class file, a DLL file at run time the software will be more need to call. If you delete When a number of applications, the software installation program records the documents it had installed and ready to be removed one by one, then it is easy to delete the dynamic-link library files there is also need to call other software run-time situation. this produced a software error. If the missing-link library file is more important core linked file, then the system will hang or crash. 6, hard disk space too little or too much debris: If the remaining hard disk space too small, because some applications run requires a lot of memory, so need virtual memory, and virtual memory is provided by the hard disk, so the hard disk have enough free space to meet the needs of virtual memory. while also training regularly defragment your hard disk, clean hard drive good habits of waste paper.
7, BOOS upgrade failed: backup BIOS in case of emergency. If your system BIOS upgrade needed, then determine the best before upgrading the BIOS version you are using it with your PC consistent. If the BIOS upgrade does not correct the process of upgrading or unexpected power failure, will result in the system may not start. so must be clear before the BIOS upgrade BIOS of the model. If you are using the current BIOS upgrade tool BIOS backup, then put the disk in the BIOS before a copy. At the same time to see whether the system BIOS whether to support recovery and also to know how to restore.
8, software upgrades inappropriate: Most people think that software upgrade is not there will be problems. In fact, during the upgrade process will share some of the components of which were also upgraded, but other programs may not support the upgraded components leading to various problems.
9, misuse of test software : the best use of the software test version of the test software is usually a bit BUC or certain not stable enough, after the use of data loss bug, crash or system can not start.
10, illegal uninstall the software: In the uninstall software, do not remove shared files, because some of the shared file system or other programs may be used, once deleted the files, some applications will not start and crashes, or of a system run crash. Do not install the software where directory directly to delete, if directly delete the registry and the Windows directory will have a lot of trash, over time, the system will run the instability caused by crashes.
11, the use of pirated software: check narcotics must be thoroughly tested, because a large some of these software with a large number of viruses, once implemented, will automatically modify your system, infection system or application software, a system crash occurs with heart.
12, application software, shortcomings inherent in the software or system not compatible: This situation is common, such as those running Windows 98 or Windows 3.X in DOS to run a good 16-bit applications. Windows 98 is 32, although it claims is compatible, but in many places is 16-bit applications can not co-ordinated. Microsoft will not make great efforts to research prepared to give up something. So if it is not necessary, it is best not to use 16-bit applications.
13, start the procedure was too more: This makes the system resources exhausted, so that individual program needs of data in memory or virtual memory in Zhaobu Dao, the system will be an unexpected error. Workaround: Do not start too many applications. in case a result, an \error \not familiar with the program.
15, non-normal shut down the computer: Do not directly use the chassis of the power button, otherwise it will create the system file is corrupted or missing, causing auto-start or run in the crash. For Windos 98/2000/NT other systems that this release is very important, otherwise serious, will cause a system crash or hard disk damage serious consequences.
16, sometimes the normal operation of software, but suddenly and inexplicably crash, reboot to run these applications it is very normal, a phenomenon called the phenomenon of suspended animation. there is more than Windows 98 because of memory resource conflict, we all know, software is running in memory, but can be released after the close of space applications. but some applications because design reasons, can not even shut down completely after the release of memory, present a software to use with a memory address, there will be conflict.
In short, Windows is indeed a place of crash of a variety of abnormal shutdown caused The solution must also be targeted, as the computer strange fault, as their solutions are different. said the reason so many computer crashes and ways to let you know, when the computer crashed, the in the end happened What, so do not panic, depending on the situation, take different solutions have only one purpose to make our computers work better.

Frequently Asked Questions
LAN troubleshooting LAN’s biggest advantage is resource sharing, but in practical use often encounter this problem: the other side obviously has shared a variety of resources to the LAN can not access them. As the result that Many species of the possibility of failure, usually novices find difficult in a short time the fault lies, so in this instance the form of LAN failure to conduct a comprehensive analysis.
1. sheep lice out of sheep – no card failure phenomenon】 【obedient
a PCI card, in Windows, can automatically install the drivers, and have properly configured network protocols and associated parameters, but in general there network when used under good behavior, after the replacement of other cards This problem still exists; and piece of card in the other computer as usual.
】 【analyze and solve network card drivers first to ensure that is correct, the best driver that is included using the card, or in accordance with the network card model to drive House (http://www.mydrivers.com) Download the appropriate driver. If there is no driver, you can chip based network card to the Lord of the manufacturers to try to install.
the network card driver installation has finished, enter \the card, but there is a conflict, and other hardware. At this point there are two solutions: First, delete or temporarily disable network card conflict with another device (such as sound cards), and then try restarting problems can be resolved if they can solve, then reinstall sound card driver or change the sound card number so that the two will not interrupt the conflict; Another way is to remove the network card driver and then reinstall, if necessary, adjust the space occupied by the interrupt number card, up until the conflict no longer occurs.
If there is a resource conflict, in the \Some cards use the interrupt address is \\Graphic conflict can BIOS will \there is a yellow exclamation mark, is obviously driven installation is not successful, but the correct driver installed N times does not work, you guessed how? later found to be loose network card.
2.
【bad environment fault phenomena 】 LAN computers to connect, share both normal copies of a few megabytes in the network, or dozens of megabytes of files are also normal, but when copying hundreds of megabytes file, one on a \prompt, and then could not find \copy data require frequent data access, which have a relatively stable transmission environment, if there is interference in the network line will make this stable environment has been destroyed, a network failure occurs. However, hubs, routers and switches and other network equipment to external interference is not very sensitive to disturbance may be the largest in the network card or cable link.
for the card, the more compact structure, if the chassis will be installed next to the graphics card, sound card and other card in the slot, these cards could lead to mutual interference between the electromagnetic wave, resulting in large file copy error occurred. workaround is to turn off the computer after unplugging the card, re-inserted in a card from or the distant sound card slot.
for the network cable is recommended you use shielded cable, this is because they are usually interference shielding layer of protection to prevent external electromagnetic interference, currently on the market five five wire cable or over shielded cables are basically. In addition, the suggestion is not in the computer, network cable and hubs and other network equipment placed near the TV sets, stereos and other appliances.
3.Ping you Ping to 10 million times – barrier
fault phenomena】 【LAN with two computers can connect to other computers and use the other computer resources, but the two computers can not Ping Tung.
【Analysis and Resolution 】 As can connect to other computers, which shows the network connections and network protocols have been no problems, so the main property is set from the software side to consider. As Ping uses the ICMP protocol, so that most failures occurred in the other computer Install a firewall software, and when the shield of the ICMP protocol. so need to check the computer’s firewall software settings to see if the shield of the ICMP protocol.
In addition, Windows XP, activating the system with the firewall, it will automatically shielding some common network capabilities. such as a computer in the network using ping command to detect the network connection status, it will see \introduction of Huixianqingqiu \, the only view that part of the computer can not view some of the computer to the LAN, even your own computer, how is this going on here?
】 【analysis and solve the premise of flow in the LAN, either can not view this machine or other computers on the network are due to the computer can not view not installed properly due to file and print sharing services.
installation file and print services in Control Panel, double-click \in the pop-up window, click the \; network \.
Also, if the LAN computer in a workgroup setting error may not be directly in a view of a working group to it. such as most computers working group is set to \group is set to \network \use \yellow, indicating that line barrier (the state of different types of card shows a different light, usually to observe). If the show is bad, use the survey line tester cable, also check card is a problem. Generally cable barrier The probability is high, less likely bad card. If you ruled out hardware failure, then proceed to Step 2.
binary Step 2: Determine whether the problem
not Internet-based machines are generally caused by local failure, individual time may be due to the campus network switching equipment or a proxy server problems. to determine whether the machine in question is the easy way to ask whether the Internet network management and other colleagues. Should the judge-based machine, please proceed to Step 3.
binary Step 3: Identify the problem or the card is the security setting set to issue
implementation of the \<10ms ttl = 128 \, if a Windows 98 system, you can reinstall IE; if the Windows 2000 system, should also look at the safety-related IP settings to determine whether there is port address shielding. If the Internet, but many sites get in, or E-mail can not log in, you must have IE be modified, re-install IE solved. If no response packet is sent, then the problem should be the network card in the machine-related settings. Should the settings identified as card-related issues, go to step 4 .
binary Step 4: Determine the network card driver installation problem or IP-related property is set incorrectly
implementation of \China to see themselves, network card drivers usually no problem, the problem should be focused on IP property settings on the network card. If the LAN computer is set to \DHCP for WINS resolution \DNS, gateway and WINS settings on the relevant. The content and the unit’s LAN configuration, please flexibility. If the ping 127.0.0.1 does not respond, then the network card drivers are installed there must be problems. re-install, and configure accordingly.
There are very special case, Ke Yi Yong ping command ping Tong Zi Ji, My Network Places Quekan not see any computer, check the TCP / IP of the Pei Zhi Du no problem, but can not Shang Wang Jiu Shi. This issue Duoshu yes the computer Bingduyinqi , the anti-virus and re-install the network card drivers can solve the problem. I’ve had several cases of this phenomenon have been using this method have been successfully resolved.

calm loop caused by broadcast storms
of: Huang Ying
author is a network management . Recently, we have to transform the local area network, network cable all the re-taking the original 70 points throughout the network, all joint topology, there are more than 30 users, just add a switch that can be had. current network structure is this: the entire network all use the star topology, the center room is equipped with a TCL of the three switches, servers mainly provide FTP, file services, Web and many other services. TCL switch used on each floor, all with with VLAN technology, each terminal by Fast Avaya network cable access network. When the network has just started all pretty good, but the network has often been dropped recently, and sometimes even strike altogether. leading to I three days to solve the problem, to and he is not on bye. Woo, woo, woo hh Fortunately, hard work pays off, three day and night to brood over after I finally buttoned the problem. Now, my colleagues have called me a yellow workers, wages will probably rise substantially, Ha ha ha hh the following Returning to the subject:
saying that one day a certain period, there are N users reflect the network connection through the time when off-line neighbors and sometimes can not be exchanged visits, as users spread across multiple floors fault, not the point of failure concentrated, were particularly bad. At first I thought the information overload switch port plug, the switch, the server restarted N times, or not do. was, we quickly begin to discuss from the software, start the server anti-virus, and then Turn off all switches, anti-virus on each machine, but the fault still exists. In the Ping network part of the server or computer, still packet loss, network intermittent.
My God, I’m really mad! day at home, carefully recalled that day failure, found that anti-virus and when I switch off the individual, the network returned to normal, and I once again plugged in to the time, they once again broken. think of here, there have been little prospect of a solution. The next day at work, I broke all the switches, then one by one to plug in, until you find the problem one. After careful observation, finally found the problem. the original was done when the network core switch and the sub-switch are left between the two cascade lines, usually inserted only one other alternative. The two switches are in the plug, and when the user switches to another user to send messages, data packets will be along the other root backup line, loop through the core switch to send packets. When large amount of information, when the core switch will be a waste of resources, resulting in speeds up to break down.
The failure was mainly due to network There exist loop, resulting in each frame is repeated in the broadcast network, causing the broadcast storm. To remove such a network loop connecting a network broadcast storm brought STP protocol can be used, we can access Cisco Systems and other related books, in This is not much to say. In addition, since we are doing the larger network, we must build more files, including network wiring diagram, IP and MAC corresponds to the table and so on, and on the wire sets of digital control. The failure have been confirmed because a new colleague carelessness.
——< br> IP and MAC binding problem
Q: My computer had a fixed IP address using the public network. In order to avoid unauthorized personnel, use \Strangely enough, after the abolition of binding in the other computer still can not use the IP address, but only in my own computer. need to explain that my computer is not a proxy server.
A: Although In the TCP / IP network, the computer often need to set IP address to communication, however, is not in fact the communication between computers via IP address, but the help of NIC’s MAC address. IP address is only used to query For Newsletter The purpose of the computer’s MAC address.
ARP protocol is used to each other’s computers, network equipment, notify your IP address corresponding to the MAC. in the computer’s ARP cache contains one or more tables for storing the IP address and The Ethernet MAC address after parsing. a computer with another IP address of computer communication, the ARP cache will be retained in the corresponding MAC address. So the next time and the same IP address, computer communications, will not MAC address of another query, but direct reference to the MAC address of the cache. Also, to note that, through the \after the start, these items will be deleted. Therefore, even if you cancel a bind, in a short time the other computer will still think you are the original IP addresses used.
in the switched network, the switch has to maintain a MAC address table, and according to MAC address to send the data to the destination computer. when binding IP and MAC address, as long as the communication with the switch off, the switch will record the MAC address. Thus, even if the back was used the same IP address, will still not work with Gateway Communications, but even outside the barrier, unless the re-start the switch, clear the MAC table, or exceeds the specified MAC address table aging time

LAN is HUB 10Mbps Ethernet connection, why file transfer only when prompted 800KB ~ 900KB / s of transmission
This is because the rate measured in different ways.
one is Bit bits, a byte is Byte . usually there in a Byte 8 Bits. network bandwidth is usually bps (nominal bit / s) as the unit of measurement, that is, \Special rates) \
hub restrictions. hub is 10Mbps shared bandwidth, if all ports are in communication state, the available transfer rate per port per second 0.625MB (calculated as 10d16). wants to be close to the theoretical obtained bandwidth transmission rate, the switch must be used as a set of line equipment.
card reasons. If card quality is not good, given the data packets are often wrong, resulting in frequent retransmissions of data packets, or receive more data packets of the wrong would lead to lower speed copy paper.
causes the wire. If the cable is too long, more powerful signal attenuation, or although the network cable from the past, but the poor quality cable can not reach theoretical speeds. In addition, When the network busy, they failed to achieve the speed.

Q: 7 users to connect through the switch and is ready to help the routing function to achieve ADSL Modem Internet Connection Sharing. ISP provides a fixed IP address, network card’s MAC address and will be binding, and the boot can access Internet, rather than the virtual dial-up. I ask, should be how to configure the ADSL Modem Internet Connection Sharing can be achieved?
A: If the IP address and ISP network card The MAC address binding together, is the routing ADSL Modem function can not be shared online. The reason is simple, each card has a unique MAC address, so other computers connected to the Internet access will be denied. the only The solution, only the ADSL Modem to connect to the ISP that has been bound MAC address of the computer, and set the computer for the proxy server, the other computer as a client-side to achieve Internet Connection Sharing.
21, Q : How to use VPN to make another visit to two local area network through the Internet? tried a machine with Modem dialing mode with the VPN can access LAN, but only found the server, do not see the other machine, why? < br> Answer: First of all be explained, VPN main role is to a client remote access VPN server or VPN server through the VPN server to access the host network. 2 LAN access each other through the Internet computer network, can only do VPN routing .
If a remote access VPN server and client where the network needs to properly configure the VPN server, mainly for remote VPN server assigned IP address of client problems. When the VPN server and the DHCP server when not on the same computer , you can use the DHCP mode for the remote client IP address assigned; when the VPN server and the DHCP server on the same computer, you can only use a static address assignment method, the \br> After the dial-up can not access the LAN, is not assigned to the LAN IP address legitimate. In addition, when using the VPN dial-up, dial-up client must have a valid IP address, or dial VPN server is meaningless.

At this point, can be no legitimate IP address of the VPN server using dynamic DNS software and applications for a domain name for this VPN server, VPN server on the client can dial this domain.
——< br > Gateway occupies 80 port
Q: I have set up the server for the Windows 2000 Server Edition operating system, open a WWW, DNS, FTP (SERV-U), E-mail (Web EasyMail) services. specified private IP address \server. Web server on port 80, but still can not access. Later, I added in the Web in 81 ports, IP-81 through the external network port can have full access to the Web page. this is need to set up port mapping (Server Adapter is a single RJ45/10Mbps LAN interface)? gateway settings will not be a problem?
A: From your question point of view, should be your gateway takes up 80 ports, and \port, through the external network IP’s 81 ports can have full access to the Web page \> determine whether a server failure, you can use the substitution:
① to look for workstations, install only the IIS (default installation), and install a network card (set 172.16.108.a and gateway is set correctly), use this platform temporary replacement of your server computer, Internet access 218.106.98.b out to see the success, if it shows you where failure, or failure at the gateway.
② you this computer from the network on a temporary break open, install a Modem, dial-up Internet access, and then in the command window, enter ipconfig, see your access to the external network address, so that other people inside IE to access your dial-up Modem access to this IP address to see whether the visit, if the description no fault of your computer; if not, then the interruption in the computer (if your IIS settings specified address, change to the correct address, that is, Modem dial-up access to the address after).

Note: the operator during use should not arbitrarily change the factory defaults. if arbitrary changes to settings can cause the machine during normal operation in accordance with the \and elimination methods, \A: No. Each ENCAD printer has a print accuracy (dpi) parameters. it directly and use Motou, nozzle size (droplet size), the number of the nozzle. give an example, NovaJet500 series printers use The Motou 300dpi, 104 nozzle .NovaJet630/700 use Motou has 208 nozzle, 600dpi print accuracy. NovaJet500 the Motou is not pre-loaded ink, there is a 20-ml ink bottle filled with to let the user pre-installed ink; NovaJet630/700 the Motou is already pre-loaded with ink.
Q: When do you need 300,600,1200 dpi printer, are suitable for those applications?
A: lower accuracy of the printer to print posters and images for the production of signs, the distance from the audience are looking at these images, so the important details are not absolute; high precision printers for the production of fine art, photo zoom, the audience will within 4 feet away to see these works. high precision printing will require a larger image file, and because of the increase in inkjet printing points more slowly.
Q: Why sometimes be the wrong spray Motou Mexico?
A: Motou error conditions caused by several jet:
1. jet hole metal plate is damaged, it may by the use of non-ENCAD ink or physical injury caused by
2. Motou resistance damage, probably because the production process, using fast print speed (such as SPEED = 10), long-term continuous use Motou cause
3. Motou plug, because there is no maintenance station cleaning Motou caused
4. Motou plug, as to leave the maintenance station Motou long, exposed to the air nozzle maintenance caused
:
love your inkjet Motou: use with caution, do not touch the copper contact area of electronic signals or inkjet hole plate, unless the cleaning, storage or replacement, do not remove the ink Motou. Do not Motou put extreme high or low temperature environment, to ensure the ink lid tightly to prevent contamination, do not mix ink, otherwise cause Motou failure.
right to do Prime: Motou in the amount of ink must be reached 18ml – 25ml between (not low or higher), users in dealing with Motou, the pumps do not force too much, but to gently click the ink to flow slowly heating Motou barn and barn to heat the air excluded, so ensures Motou heated barn there is no negative pressure ink jet can smoothly to the screen.
back guarantee Motou contacts clean: you must be at work before check whether Motou drops behind the contact, if droplet spray chart will have a very regular needle phenomenon can even affect the other three good Motou, so we must pay attention to this phenomenon. to ensure a clean contact cable, do not make contact with the cable contacts on the ink, the ink will appear if the above phenomenon .
NOVAJET machine output problems
ENCAD NOVAJET Inkjet Printer (more than 630 models) in the same types of inkjet printers in the printing speed is relatively fast, so the output with a dedicated computer with the hardware requirements correspondingly higher. such as the use of Mongolia and Thailand RIP, requires PIII500 or above, 256M RAM, IDE hard disk 7200. such as the use AccuPrintRIP, requires configuration can lower, but the RIP where to be enough hard disk space, at least 4GB or more . When the above configuration are the appropriate things right, you can normally print. but many users will run into a problem: When printing inkjet printers, ink vehicles on both sides of pause phenomena occur, resulting in slower printing speed. Here is the main reason for printing machine did not realize that the ECP printer port on the computer, we can find a variety of reasons from different solutions:
a hardware problem:
1. print line and password dog a bad connection
Solution: Check the connection components, such as print lines or the password found in a dog with needle or damaged, replace and re-connect.
2. print with a hand line is too long or intermediate connector.
solution: print line can not be too long preferably within 3 meters, but the middle is best not to even demultiplexer.
3. using non-Intel chipsets, computer motherboards.
solution: only Intel chipset can let Windows recognize the standard ECP Print port, while others such as VIA, SIS chipset, only to realize that non-standard ECP. If your computer is a non-Intel chipset motherboard, immediately replaced.
Second, software problems:
system is damaged or changed, it is most frequently occurring phenomenon.
Solution: When checking the hardware are OK, and reinstall Windows or ECP output not recognized, the main method is to reinstall the system does not, the correct steps are as follows:
1. Back DOS state, the PRO-1 Windows and rename the directory name.
2. reinstall Windows, and configured hardware.
3. Check Windows is denied to the ECP printer port.
4. reinstall Photoshop or CorelDRAW, etc..
5. reinstall AccuPrint or Mongolia and Thailand and so on.
6. print images, from printing to see if the panel received ECP
II: on the causes of broken ink
:
nozzle circuit burned out.
true plug nozzle.
inking tubes, ink residue remaining plug.
warm enough value.
solution:
such as nozzle circuit burn, photo opportunities automatic detection and compensation, so that aircraft can still maintain a good photo printing.
such as nozzle clogging, can explore the use of ultrasonic cleaning, or hot distilled water cleaning nozzle.
if they can not clear the blockage nozzle, you must use manual nozzle compensation.
even if each color of ink nozzles together have 2m3 burn or blockage, use of automatic or manual nozzle compensation can make good photo printing machine, no need to immediately replace the ink cartridge .
washed with distilled water each inking pipeline.
causes of low room temperature, the ink evenly from right to left, can improve the preheating value.
regular cleaning of large ink tank of the residue ( recommended once a month).
photo machine using original ENCAD ink.
2.
ink is too big reason:
RIP (play Chart software) to control ink option is set too high.
ink of bad media (especially at low temperatures) / coating evenly.
solution:
pass RIP (play Chart software) to control ink option lower the ink volume, if RIP (hit chart software without the appropriate option, you need to lower the ink through the machine control panel.
replacement ink quality and good uniformity or medium or raise the ambient temperature.
3 photo machine which \error, shut down; carriage axis failure message, can not continue to move.
reasons:
some parts are dirt / dirty, causing bracket operation is not smooth.
some parts are damaged / loss phenomenon, leading to action.
long-term low temperature operation, the copper sleeve, plastic conveyor causing increased resistance.
solution:
Clean the following components (recommended ENCAD EASYKLEAN cleaning fluid):
A, sliding rotation axis
B, copper set
C, top and bottom of the article grating
if there was a slight delay traffic in Dayton, may support the bottom of the slip surface grating affixed broken / viscose overflow, or Mexican chain stent deformation, contact the service center as soon as possible.
if there is delay traffic in the left and right ends of Dayton, may be due to improper use of lubricants makes the rotation axis support under the plastic case of the two oil expansion, leading to Copper cover rubs. Please EASY KLEAN
cleaner clean copper sleeve, wipe the excess oil.
4. India ink vehicles move about when there is pause, and even slow down the printing speed.
reasons
print each line number will significantly affect the data transmission needs, the fewer the number of print, the more information required, the following factors will affect the printing speed.
RIP too slow, lack of information lead to the transmission .
set the print times too small, inadequate coordination with the RIP.
slow computer speed.
solution:
increase the speed of RIP, such as increasing computer memory and upgrade the central processing etc. , optimizing overall PPC match performance, close other programs, one run RIP transferred to raster image files.
change the printing number of times, usually best to \Standard IEEE1284 printer cable, printer cable should not be too long to determine the computer printer port to \to NVRAM invalid> \access to resources should be set to the same mm before, but do not change the settings> general parallel port DMA set to 3, IRQ setting set to # 07, so sure no other devices on this binary and, if necessary optional \; to automatically change the configuration to correctly configure the printing parameters, often IRQ address conflicts with other devices may .
RIP software to read the instructions to confirm: RGB / CMYK mode, rotating, stratified / non-hierarchical, Mongolia board / Cancel mask, mirror / no mirror so set on the printing speed and print quality.
Note: If the computer system WINDOWSNT, must occur for this problem because WINDOWSNT print port to \Change the computer’s BLOS EPP. the actual output is \br> Paper Detector dirty / damaged.
near table damaged part of the plate coating, loss of function.
paper sensor damage.
white lines correspond to grating profile control near the wound .
solution:
paper will address the sensor clean.
check the black base coating, if any coating off, try black oil paint fill.

machine maintenance and routine maintenance considerations

1, whom the ambient temperature to maintain room temperature (about 22 degrees Celsius), there is a certain humidity, dust as small as possible.
2, regular maintenance of the machine, reducing Small dust, ink and other effects on the machine, specific projects and the time table below:
car sliding axis daily wipe with a clean cloth or paper towel and alcohol is prohibited in any clocks rub oil
cartridge (clear ink head of the small box) weekly cleaning, remove the water rinse, wipe ink film and the right not to lose homing
grating section weekly cleaning, daily observation, Cotton + distilled water or alcohol wipe down, do not be too strong
Mexican trucks and Motou the contact pieces daily checks to ensure no ink, dirt and possible anti-too much wine clear solution Microelectronics
Note: The above recommended cleaning and maintenance ENCAD EASY KIEAN cleaning solution.
3 , careful not to use oil-based ink, oil-based ink systems for perishable and plug Motou. Original ink is your best choice. mix ink to use.
4, can not hot plug print line, or they will pull the main cause damage.
5, attention Motou not wipe the nozzle, the ink can not shed good quality cloth or paper towel to wipe stick and sucks it off you can, or may lead to ink hole to plug.
6, the machine must connected to the ground; when air dry electrostatic problem can not be ignored, when using some of the gum and light film medium, multi-band electrostatic charge (especially when feeding work very fast); electrostatic charge can result in the machine and Motou Security damage to the power ground wire to release static electricity, so in the live action Motou, ensure that your hands have been discharged, (touching a grounded metal body or wear static bracelet, otherwise easily lead to damage Motou individual dots.
grounding requirements and methods:
grounding wire should be mechanically strong volume flexible single strand copper wire or cable.
take place can not be shared with the building lightning rod in the ground.
line ends to be welded line pin on the end use of bolts in the machine control panel closely metal bottom, the other end connected to the building’s ground-line or real buried in the ground water (note the electrical conductivity is good). In severe cases, electrostatic, ground connection may take more than the method.
7, can not use cutter to cut the machine manually instead of automatically paper cutting paper, it will scratch the machine table and cause the machine does not recognize normal paper.
8, large ink supply system Dasheng keep 1/2m3/4 ink cartridges around, there should be bubbles in the ink tube, install the new Motou preceded with 20ml of ink, or may cause no ink or Lou Mo .
9, forward backward advance and retreat of paper, it can not hold down a key forward or backward for too long, should be key not more than 10 seconds, pause and then continue, otherwise it will lead stepper motor or motherboard damage .
10, half-way operation Motou, we must be careful not to let the ink spilled into the small car of the motherboard, Motou reset, the observation car stop bit table, the optical axis, raster (especially) with or without sewage ink, if are set to ink stain should be immediately cleared.
11, definitely not in the boot state machine behind the photo pulled from NJ850 DTD (dryers), power supply and signal thread, at any time to plug and quick-drying machine The signal line plug, must ensure NJ850 photo switch off the power head and pull it will lead to DTD (dryers) function is not normal.
12, should be cleaned regularly large ink tank filter residue to Anti-settling at the bottom line and plug into the pipeline Motou.
13, exercise log into the staff develop a good habit to do operations (especially when the shift), records the machine at different temperatures, temperature and other climate, in various materials on paper and a variety of specific parameters for printing various types of printed documents, review the best experience.
14, recommended: NJ850 photo machine using ONXYPostershop5.5 or ACCUPINT (good friend) printing software (RIP) in print mode 1 * 84PASS bracket 10, the best print results.
