computer, print cable two pull down the re inserted, careful not to live plug. If the problem can not be solved, the replacement of a print cable to try, or replace.

Five, the printer is not complete, common daily breakdown of printing

Printer common hardware failure and processing method:

Symptoms: printer paper. Paper also appeared after the paper shortage alarm sound, installed a piece of paper rollers do not pull paper and need to hold more than two pieces of paper rollers before they can pull the paper. Cause analysis of the general pin type or inkjet printer with a photoelectric sensor is equipped with a photoelectric sensor to detect whether the lack of paper. In normal circumstances, when the paper is loaded with paper, the photoelectric sensor is touched by the paper. If the photoelectric sensor for a long time not clean, photoelectric sensor surface will be attached to the scraps of paper, dust, etc., makes the sensor surface dirty, not photosensitive correctly, there will be false positives. Several of the above phenomenon is basically the same problem, the photoelectric sensor surface caused by dirt.

Handling method to unplug the power, open the machine cover. For most of the needle type printer (such as lq- 1600K Epson, star-3200, etc.), to remove the upper cover, and the print head parallel to the top of the print head of a small cover (about 20 cm long 1 cm wide), the print head pushed to the middle (inkjet printers generally do not have this small cover), so you can remove the cover, otherwise it can not get down. Unload printer peripheral screw (most) at the bottom of the printer and slowly activities can the shell open, and remove the black under the paper feed roller, attention should be paid to the feed roller on both sides by a cutting groove by two iron stuck, just push it and make it rotate around the roller, can get the paper and. At the same time the paper and saw a small photoelectric sensor, remove dirt around, with alcohol cotton swab head and rub off the stain, re install paper roller, a machine cover, start, solve the problem.

Symptoms two: when the print is clear, while the other side is not clear. Reason analysis of this phenomenon is generally appear in the needle type printer, ink jet printer may also occur, but the probability is small, mainly print head guide rail and print roller is not parallel, resulting in both of the distance is far from near. The processing method can adjust the distance between the print head guide rail and the printing roller, making it parallel. Specific approach is: the first two side of the print head guide rails on both sides of the nut, the left and right sides of the nut has a regulation, the adjustment of the two sides of the film, the counter clockwise rotation adjustment piece to reduce the gap, the last to print head guide rail parallel with the printing roller can solve the problem. Should pay attention to adjust the direction of the right direction, can be gradually adjusted, more than a few times to fight. Three symptoms: print the feeling when the print head resistance, print will stop ringing or vibration issued in place. Cause analysis of print head long rail sliding time will become dry, moves the print head will be blocked, to a certain extent can stop the printing, serious can burn the driving circuit.

Processing method in the printing of a few drops of oil on the print, back and forth to move the print head, so that it is uniform. Re boot, if there is this phenomenon, it may be the driver needs to get burned, repair department. Four symptoms: print characters and incomplete, character is not clear. Reasons for the analysis of ink jet printers, there may be two reasons: 1 ink cartridges,

2 long time without or subject to direct sunlight, ink nozzle blockage. For needle type printer may be the following reasons: 1. Print ribbon used when too long; 2. Print head for a long time not clean, dirty too much; 3. Print head broken needle; 4. Print head driving circuit fault.

Approach for an inkjet printer, can change new cartridges or injecting ink. When the ink cartridge is unused, it can be concluded that is ink nozzle clogging: take cartridges (for cartridge of the nozzle is one of the printer, you need to get under the nozzle, but need to be carefully), put the nozzle in the warm water soak for a while. Note that must not be the portion of the circuit board is also immersed in the water, otherwise the consequences could be disastrous, with absorbent paper suck dip some water, installed after washing several times nozzle can be. For the printer, can adjust the distance between the printing head and printing roller (around the print head moving line can be found), if not, can change the new ribbon, if not, you need to clean the print head, the method is: remove the print head of the two fixing screws, with the print head, with a clear print head, needle or hooks after inclusion of dirt, is generally a long time accumulation of ribbon fiber, the rear visible print head needle in place a few drops of oil to remove the instrument, some stubborn dirt, do not install the ribbon playing a few sheets of paper, and then put on a ribbon, this problem can be resolved, if the print head is broken needle or drive circuit, it had to get to the repair department.

Symptoms five: the printer does not have any response after the boot, simply do not work. Analysis of the causes of printers have overcurrent protection device, when the current is too large will lead to electrical protection, this phenomenon is basically printer insurance pipe burn. Approach to open the cabinet, inside the printer power supply part find an insurance tube (internal power supply part in playing the printing machine is connected with a power supply near can be found), to see whether it is black, or with a multimeter measuring about whether the burn. If burned, insurance and consistent exchange tube can be (insurance tube are marked with rated current).

Six symptoms: printing paper sanritusone of uneven thickness of the black line, serious when the entire piece of paper is like this effect. Reason analysis this phenomenon is generally appear in the needle type printer, the reason is that the print head is too dirty or print head and the printing roller spacing is too small or too thick to print paper. Processing method to remove the print head, clean the print head, or to adjust the print head and the spacing between the printing roller.

To penda and Mexico should know matters 1, if the print cartridges and nozzle is integrated together, then for the ink cartridge with ink, be sure to pay attention to protect the cartridge nozzle from harm, otherwise nozzle when a blocked or damaged, the ink can not be repeated use of the. Also due to the use of ink cartridges in the process of frequent use, the nozzle may be splashed back into the paper fiber, resulting in poor output effect, so it is necessary to clean the nozzle is also very necessary; cleaning nozzle, should try to use wet paper towels and no cotton towel gently clean the nozzle, and do not touch the nozzle, and then use the ink jet printer control panel on the cleaning action, until the print output effect is clear. 2, because some cartridges have a special ink filling hole, to these cartridges Zhumo before, the general must be the ink in the ink injection hole plug first remove the, then in accordance with the correct procedure finished filling ink cartridge, must also be refilling hole plug to the back of the cover, otherwise, ink-jet printing

machine to work will happen to jilt ink phenomenon to smear inkjet printer inside the panel. 3, many users in the ink jet ink, the general will choose to ink indicator light ink, but for the old ink jet printer, the ink can not be based on the printer to change ink, but these are not ink indicator of ink jet cartridges are transparent, so we can observe the method through the eyes

4, many for the first time to penda cartridge canned ink users, often wrong that the ink cartridges in the tank is full now, so you can extend the use time of the cartridge, in fact, we each filled with ink, it is best to ink cans to about 90% of the capacity of the cartridge, such as fruit more than the capacity, inside the cartridge in the corpus cavernosum may can not absorb too much ink ink overflow phenomenon, thereby causing the pollution to the ink jet printer.

5, in the ink cartridge can be good ink, it is best not to put the cartridge back into the box, because many of the cartridges are contained in the use of ink sponge pad, and sponge pad ink absorption, so that the ink can be absorbed by the sponge pad, so that the ink cartridge is placed in a few minutes, so that the ink slowly penetrate into every corner of the sponge pad, so as to ensure the final print quality.

Printer usage notes

Due to the internal components of the printer is more sophisticated, even if it is common to wipe or add oil are likely to produce an image of the print quality can not be underestimated, so the internal clean-up must be careful, according to my experience, the following can be cleaned parts, for large reference.

1 toner protection device

Printer cartridges will have some pads, their role is excess toner absorption in the system of the paper transmission drum. The user can remove it from the machine, use the manual way to clean up. General in the new ink cartridge also contains a new liner.

2 paper roller

They are the transmission portion of the printer, the paper from the paper groove drag to the printer, but in the process, paper was stained with the grease and dirt will precipitate in the roller, a long time without cleaning will lead to cardboard and paper feed error, which is printers are most prone to failure. Here, we can use the alcohol soaked cotton or cloth to clean these sediments. In addition, there are special roller cleaner in some professional office equipment stores.

3 coronary wire

They are specialized wires that are used to transmit electricity within the printer. Static electricity is used to toner attracted to the paper, but dust precipitation will static electricity use efficiency (especially for some old-fashioned laser printer influence especially). Users can use cotton cloth to gently wipe the dust, but please do not use alcohol or other solvents, they will affect the effect of the printer, the general in the old-fashioned laser printer, the printer is exposed to the. If you can't find them, the printer's manual will indicate their location.

4.

Similar to the computer internal, many laser printers have internal fans, the perennial work will be dust and dirt blocking. We must ensure that regular cleaning of air vents and leaf fan, keep the air flow inside the printer.

Within the laser printer can be cleaned parts, but we must pay attention to: due to laser printers are using high heat method the toner adsorption to the paper. So keep in mind that when you have just finished the printer's work, the printer's cleaning work, and note that all parts with temperature warning signs. We could see some special laser printer \

office supplies store, their surface is covered with special paper can adsorption printer paper path of dirt and excess toner, and because they will after a printout of the complete process, so to clean the inside of the printer is the most thorough of.

Printer external cleaning

Compared with the internal cleaning, the external cleaning of the printer is relatively easy and safe. General users can use the cleaning / protection spray when cleaning the outside surface of the computer hardware, which can help reduce the static electricity, the surface of the plastic is relatively safe. Can the cleaning agents are sprayed on the soft cloth, and then use it to wipe the equipment shell (be careful not to the spray is injected into the interior of the machine, at the same time, when cleaning the outside of the printer, we can also through the air outlet, fan channel and paper slot blowing compressed air, to remove dust and dirt.

Printer is delicate products, although not, but because of a long time in the environment of high temperature, regular cleaning and maintenance can prolong its life. January in general outside a cleaning and two months of internal to an internal cleaning, can greatly improve the working efficiency of the printer, why not do it?

Printer usage notes

1 if the printer produces fever, smoke, smell, there is abnormal sound, etc., please cut off the power and information staff.

2 other items are forbidden on the printer. When the printer is not in use for a long time, unplug the power plug from the power outlet.

In case 3, when in the vicinity of thunder, will pull out the power plug from the socket. If you insert, the machine will be damaged.

4 print paper and ribbon box is not set, the prohibition of printing. Print head and print roll will be damaged.

5 print head in high temperature state. No contact before the temperature drops. To prevent burns, injuries.

6 do not touch the printed cable connector and the metal part of the print head. Print head, do not touch the print head.

7 when the print head work, prohibit cutting off power.

8 please do not disassemble, move, drag, if there is fault, please contact the personnel information.

9 prohibit foreign bodies (staples, sheet metal, liquid) into the machine, otherwise it will cause electric shock or fault.

10 in order to ensure that the printer power supply normal, data and computer connections can be started.

11 printer in print when moving, do not drag, turn off the printer.

12 for the same repeat of the print file, please do not exceed 5, more than 5 copies should be received on the front desk copy.

13 in the print is too large, should be kept in 30 copies of the amount of printing to make the printer to rest for 5-10 minutes, so as to avoid overheating and damage to the printer.

14 in the print file, do not allow the use of the thickness is too high (more than 80g) of paper, do not allow the use of wrinkles, folding paper.

15 if the printer in the emergence of serious physical damage, artificial damage or not according to the above operation specifications and the printer will be responsible for damage to

the damage.
