Printer common problems and solutions?
In the office, inkjet printers are a more convenient device. Inkjet printers often have some problems due to improper use, maintenance, and improper operation. How to solve them is a concern of users.
Common fault one: the ink is scarce when printing, and the writing is unrecognizable. Most of the faults are caused by long-term use of the printer or other reasons, resulting in obstacles in the ink delivery system or nozzle clogging.
Exclusion method: If the nozzle is not blocked very much, then directly perform the cleaning operation on the printer. If there is still no effect after repeated cleaning, you can take down the ink cartridge (for the non-integrated printer nozzle, you need to take the nozzle, but need to be careful), soak the nozzle in warm water for a while, be careful not to put the board Part of it is also immersed in water, otherwise the consequences are unimaginable. Use absorbent paper to absorb the water droplets that have been stained, and then clean the nozzle several times after loading.
Common fault 2: After replacing the new ink cartridge, the "ink" light on the panel is turned on when the printer is turned on.
Under normal circumstances, the "ink out" light will only illuminate when the ink has run out. After replacing the new ink cartridge, the "ink out" light on the printer panel is still on. This kind of failure occurs. First, it is possible that the ink cartridge is not installed. Another possibility is to take the old ink cartridge and replace it with a new one. Ink cartridge. Because the printer will refill the ink delivery system after replacing the cartridge, this process will not work in the off state, making it impossible for the printer to detect the cartridge being reinstalled. In addition, some printers measure the ink capacity by using an electronic counter inside the printer (especially in the statistics of the amount of color ink used). When the counter reaches a certain value, the printer judges that the ink is used up. During the cartridge replacement process, the printer resets its internal electronic counter to confirm that a new cartridge has been installed.

Solution: Turn on the power and move the printhead to the cartridge replacement position. After the ink cartridge is installed, let the printer charge the ink. After the ink filling process is finished, the fault is eliminated.
Common fault three: the treatment of the nozzle soft plug
The plugging of the soft plug refers to the disconnection failure caused by the viscosity of the ink on the nozzle due to various reasons. Generally, the original ink tank can be recovered after repeated cleaning, but such a method wastes ink. The easiest way is to use the empty ink cartridge in your hand to clean the nozzle. Before cleaning with an empty ink cartridge, first use a needle tube to extract the residual ink in the ink cartridge as much as possible. The cleaner the better, then add the cleaning solution (available in the accessories market). When filling the cleaning solution, it should be carried out in a clean environment. Press the ink cartridge with the cleaning solution in accordance with the normal operation of the printer, and press the cleaning button of the printer to clean it. The printing test is performed by using the light color mixed with the residual ink in the ink cartridge and the cleaning liquid, and then the good ink cartridge can be used after being replaced.
Common fault four: fault handling of printer cleaning pump nozzle
There are many problems with the printer cleaning the pump nozzle, and it is also one of the main factors causing the plug. The printer cleaning nozzle is decisive for the protection of the printer nozzle. After the nozzle car returns to the position, the nozzle should be weakly pumped by the cleaning pump nozzle to seal the nozzle. When the printer installs a new ink cartridge or the nozzle is broken, the suction pump at the lower end of the machine is used to pump the nozzle. The higher the precision of the nozzle, the better. However, in actual use, its performance and airtightness will decrease due to prolonged time and increased residual coagulum of dust and ink in the mouth. If the user does not check or clean it frequently, it will cause some troubles in your printer's nozzle.

How to maintain this part: Remove the top cover of the printer and remove the trolley. Rinse the pure water with a needle tube, especially the micro-hole gasket embedded in the mouth. It is important to remind users that when cleaning this part, it must not be cleaned with ethanol or methanol, which will cause the microporous gasket embedded in this assembly to dissolve and deform. In addition, it is necessary to keep the inkjet printer away from the high temperature and dust working environment. Only a good working environment can ensure the long-term normal use of the machine.
Common fault five: the processing of detecting the normal ink line and the printing accuracy is obviously deteriorated
In the inkjet printer, the printing accuracy is gradually deteriorated due to the number of times of use and the length of time. Inkjet printer heads also have a long life. Generally, a new nozzle will be used from the beginning to the end of its life. If there is no fault, it is the life of 20-40 cartridges. If your printer has been used for a long time, the printing accuracy is getting worse. You can try to replace the ink cartridge. If you change the ink cartridge and the output will print the same result, then the nozzle of your printer will be replaced. It is. If there is a change after replacing the ink cartridge, it may be that you are using a non-genuine ink of poor quality.

If the printer is new, the printed result is not satisfactory, and the print line segment is unclear, the text pattern is skewed, the outer boundary of the text pattern is blurred, and the print ink control synchronization accuracy is poor. This means that you may be buying a fake ink cartridge or using it. The ink cartridge is a non-original product and should be replaced immediately.
Common fault six: the handling of the wrong position of the walking trolley
The track of the inkjet printer walking trolley is slid by the precise combination of two powder alloy copper sleeves and a round steel shaft. Although the traveling trolley is designed with a piece of linoleum to supplement the lubricating oil on the shaft, there are dust everywhere in our living environment. For a long time, the lubricating oil on the shaft surface will be deteriorated due to the oxidation of air and the destruction of dust. If it fails, if the printer continues to be used, the friction between the shaft and the copper sleeve will increase, and the carriage will be misaligned until it hits the front of the vehicle.

The solution is to turn off the printer power immediately after the fault occurs, and push the unreturned cart back to the parking space by hand. Look for a small piece of sponge or felt, put it in the sewing machine oil, and rub it with the tweezers on the spindle. It is best to remove the spindle and wash it and oil it. This works best.

Another type of car is caused by damage to the device. Above the printer car parking space is a photoelectric sensor, which is an important component that provides a printer car reset signal to the printer's main board. If the component is too dusty or damaged, the printer's car will not be able to use the car because it cannot find the return signal. Generally, the device needs to be replaced when the fault occurs.
