How to handle printer failures
When the printer is unable to automatically re-route during the printing process, the printing work cannot be completed, and the problem can be solved by modifying the registry.
Expand the "HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Printers" subkey in the open Registry Editor window and change the "PruneDownlevel" value to "2". After restarting the computer, the fault disappears.
Most of the failures are caused by long-term use of the printer or other reasons, resulting in obstacles in the ink delivery system or clogging of the nozzle. If the nozzle is not blocked so much, simply 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.
After replacing the new ink cartridge, the printer will be able to light up when the ink is used up. After replacing the new ink cartridge, the "ink" 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. New ink cartridges. 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.
Turn on the power and move the print head to the ink 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.
