Printers are a very common and very important device in people's lives and production, and their variety of products in the current market is divided into three main categories. The difference is..Laser printersI don't knowInkjet printerAndNeedle printerFor these three types of printers, the techniques and methods of repair vary greatly, and relate specifically to the principles in which the printer operates, its structure, etc. In particular, the basic maintenance methods of the printers are described in detail for users in the subsection below。

I. Laser printers
1. All black output
Possible causes of failure: (1) if the laser is definitely good, it may charge the electrodes and grid short circuits; (2) there is a logical error in the scanning-driven circuit; (3) there is a poor discharge of the selenium drum component; and (4) there is no connection。
2. ... Output full vertical black belts (lines)
Possible causes of failure: (1) damaged permafrost or bruised permafrost on the slab; (2) partial damage to magnetic scaffold; (3) contamination of printer (general guide paper channel) by ink。
3. Output horizontal irregular black belt (line)
Possible causes of failure: (1) poor exposure of the sensory drum to the electrodes; (2) excessive cutting of the sensory pallet; (3) dithering of the sensory drum master when the gear turns; (4) defective or incorrect installation of the sensory drum。
4. Output full white paper
Possible causes of failure: (1) ink is no longer in the powder box; (2) laser mechanical fast doors are not open; (3) laser beam detector contamination or damage; (4) laser damage。
5. ... Output vertically ruled white bands (bars)
Possible causes of failure: (1) when the ink is about to run out, there is no ink on the magnetic field (usually in the middle of the sample); (2) beam mirrors are contaminated with dirty materials such as ink; and (3) scanning light paths are masked by foreign objects。
6. Output horizontal irregular strips (bands)
Possible causes of failure: (1) charged wiring or poor contact with recharged rims; (2) exhaustion of the optical catheter on the surface of the sensed drum; and (3) poor discharge of the sensed drum。
7. Output text plain
Possible causes of failure: (1) the printing paper is damp; (2) the ink powder is fluent or is a photodrum component problem; (3) the sensor drum is out of charge and the surface is low; (4) it is under-exposed; (5) it is under-pressure; (6) it is low。
8. Output image lapses
Possible causes of failure: (1) use of non-standard print paper; (2) ink powder model not compatible with machine type or ink infestation; (3) luminous tones; (4) parts of the scanning assembly loose; (5) scanners are not functioning smoothly and are shaking。
Ii. Inkjet printers
1. Addressing the sticker problem
It is generally shown as two or more pieces of paper at a time, which results in the printer not eating properly and thus stopping。
The problem is usually caused by two reasons: paper is more current, and the problem is better solved by baking the paper, either on the heating tablet or on the monitor, but not for too long. The second is the fact that most of the paper bought from the store was just taken out of the box, which was squeezed over a longer period of time to form a whole, which is prone to this phenomenon. The solution would be to move back and forth with both hands on the paper before loading it into the printer, so that each piece of paper would be active, so that the head of paper would form a neat slope so that the slope would be down to the box, so that there would be no more sticky paper。
2. Addressing the cardboard issue
In many cases, the cardboard was the result of improper use. When a paper problem occurs, the printer power is shut down, and it is decided whether to remove paper from the outside or from the inside, depending on the cardpaper. Particular care should be taken at this time to prevent paper from being left inside the printer。
In order to avoid printers, the following aspects should be noted: before printing, it is advisable to check whether there is a "paper size selector" switch on the printer panel or in the slider, and, if so, select a4 or letter depending on the medium size used, so that the paper is not difficult to slip in. (b) tilt to create cardboard; the paper should not be too thin or too thick; when adding paper to a paper slot, it is important to remove the original paper and fix it with the newly added paper before putting it back into the paper slot, so that the printer does not draw more than one piece of paper at a time to create a cardpaper when printing; and whether the paper is spilled over and put into the paper slot at the time of adding paper, so that the paper is not glued to the wetness or other factors together, it's causing more than one piece of paper to get involved。
3. Addressing non-entry paper
It is generally expressed in the light of the sound of the incoming wheel that the paper cannot be eaten, resulting in the computer alerting the printer to lack paper and to stop printing. It is believed that many users have experienced such problems. I'm also experiencing this。
The main reason for this problem is that because the room is too dry, the drying of the paper can result in less friction between the feeder and the paper, so that the paper can be slipped. The only way to solve the problem was to increase the humidity of the room, but it was important to keep it under control, otherwise it would cause another problem. And the other thing is to be careful, not to let the printer get near the heater, not to let the heater look straight at the printer, especially the type of stone pipe, the direct-fire heater, which, in addition to causing problems like non-input paper, causes the ink spray head to dry up, making it unprintable。
Iii. Needle printers
1. Fragmented ribbons. The ribbons were overstretched, and the cords were broken or broken by a hammer. In the first case, the fractured part could be cut off and re-sewed; in the latter case, the color belt could be replaced。
The colour belt is marked. The edges of the ribbons are discolored and the hair is attached to the wheel, which leads to the gravitation of the wheel, which is not properly indentible. The solution would be to first open the printer's cap, open the handles of the rotation arm with the hammer, pull the tape back gently at the delivery end of the tape box, and then close the handles of the transfer arm with the hammer, turn on the power source, and then put the tape back on the tape when self-checked。
Iii. Hall effector damage. The color belts were frequent, and the hole effector was continuously squeezed, causing damage to break. This failure can only be replaced by a change in the color belt or a replacement with a colour belt motion sensor。
4. The colour belt active wheel-drive wear and tear. This failure is due to the long duration of the driving belt or the char link friction drive. The solution is to reposition the character chain so that it does not rub the drive belt; replace it if it breaks。
5. There is an unwarranted interruption in the movement of colour belts. First, check if the belt motion sensor signal line has been damaged and, if broken, replace the signal line; then check if the tape motion sensor signal line at the j6 interpolation on the interlocking panel is damaged or poorly exposed。
And now the quality of their products continues to improve with the development of modern science and technology. However, whatever the quality of the printer products, problems arise more or less in the long-term state of use, either because of their own equipment, or because they may be caused by human operation, due to improper use. Face something commonPrinter failureAt the same time, if users had some knowledge of their maintenance, they would not be helpless。
