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.
5. check the computer’s hard disk space is too small. If less than 10MB hard disk space available is not printing, check is in the \; property \documents, to free more space.
6. Check whether the appropriate printer driver and print a configuration is correct. In the \\should focus on examination of \the BIOS setup the printer port is open. 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
more common failure treatment Ink Print a blank area
writing or pictures is not continuous, there are gaps in the law, bar ink channel in the first three seconds of air by washing or by the printer application tools The print head cleaning print head cleaning
head plug Ibid, if not solve the problem after 3 times, you need to change with special dipping or head
used a color ink cartridge replacement / no the ink to print out the white / no ink
1, the print head completely blocked the way with print blank
2, the upper vent of the yellow ink cartridge seal cartridge is not torn out, torn yellow seal
3, replace the motherboard burned out F1 F1
the insurance does not recognize the printer ink after ink cartridge installation to make light still bright
1, not under the normal procedure to re-install the ink cartridges to install an ink cartridge according to normal procedures < br> 2, the test ink nozzle metal deformation, corrosion or oil out cartridges, adjust, clean metal and then reinstall

1, rail, rail to replace the word car badly worn, the word car, linoleum
2, the lack of lubricating oil clean guide, the word car filling special lubricants
3, lower temperature to improve the working environment temperature
4, external stop word removal word car channel car debris on the color offset printing
out the difference between color and larger screen
1, lack of color (the color does not emit a certain or used) to print a blank area with
2, the print head properly use special software to adjust the angle adjustments
3, printing paper or cartridges to replace unqualified or qualified printing paper into the paper cartridge
abnormal
1, feed is not in place to block a foreign body into the paper clear the way for foreign
2, into the paper folding
3, into the frame deformation adjustment or replacement of paper into the paper planes
4, into the paper planes in the dislocation of dislocation parts Parts
5, a summary paper on both sides of wheel wear on both sides of the group of inconsistent, its replacement will be on both sides of paper or photo paper round round rubber cover transposition
6, replace the paper meet the quality requirements of uneven paper
feed continuously
1, summarized serious while wearing roller replacement wheel on both sides of paper or photo paper round rubber cover on both sides of summary transposition
2, summary paper round on a dust wipe with ethanol Photo Paper round
not online / playing garbled
1, driver does not select the correct drive or reinstall the driver
2, motherboard fault repair or replace the motherboard
computer prompts a variety of information such as: out of paper, time-out error, cable not connected
1, out of paper or ink to make lamp lights according to the paper key to re-feed, or for ink
2, print cable not plugged in or plugged in or replace the damaged re-print cable
3, motherboard interface or chip burned
laser printer in use should note the following:
1, the printer must have a good chassis ground wire. Otherwise, the printer will generate static electricity machine Performance instability, affect the kind of quality, and in severe damage to machines and wounded people.
2, the printer more high pressure, high temperature and can not just open the cabinet.
3, the machine power is larger , the frequency of high temperature SCR solution made the best use of a separate power supply.
4, paper jam occurs in the course of time. must first determine the cardboard parts, and then gently, with a clever edge the cardboard out. Otherwise, damage to the parts or scraps of paper left in the machine affect the kind of quality.
5, printer paper, not be less than 52g / square meter, the maximum can not exceed 130g / square meter, the most good is offset paper or copy paper. copperplate paper can not be used for laser printers, printing process is mainly caused by etching blistering heat setting, affect the use.
6, the printer is concluded, the maintenance of cleaning efforts. on optical part of the clean-up with particular attention to not crash, metal tools can not touch Gu Xin, to avoid permanent damage. in the clean-up, the laser is not visible attention to eye protection.
7, users can produce their own core needs regular replacement cartridge, repeat load toner, toner cartridges can be repeatedly used body; or simply cleaning up can get high-quality text, graphics and so on.
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. ..
