2. Or pay attention to the location of your printer. If there is a problem with the location of the printer, it will also cause it to fail to work.
3. If all this fails, turn off the printer, then take out the ink cartridge and try to adjust and install it. Not yet. Check the driver and reinstall the driver.
4. If the above cannot be solved, it may be that the metal sheet on the ink cartridge has not been used for a long time and the contact is poor. Take out the ink cartridge and clean it with an eraser. You will find that the metal plate on the ink cartridge is shining. If you reinstall, there will generally be no problem.
5. If the problem cannot be solved, it is necessary to consider whether the ink cartridge is damaged, and it is recommended to replace the ink cartridge.
6. It is recommended to contact professional maintenance personnel for maintenance.

Troubleshooting the printer:
Fault symptom: the printer has bottom ash when printing.
1. Adjust the print density knob to the middle position (some models need printer driver adjustment), and observe whether the bottom ash phenomenon has improved. If there is any change, it means that the magnetic roller bias is too low. Under normal circumstances, as long as the printing density is within the adjustment range, there should be no bottom ash phenomenon.
Clean the magnetic roller contact to ensure good contact. Then use a multimeter to measure the development bias, which should generally be between -250V and-350 V. Different models have different bias values. If the deviation is too large, it should be repaired or adjusted to the specified value.
2. Check the magnetic roller scraper. Take out the toner cartridge assembly and rotate the moving photosensitive drum in the paper feed direction. If toner sticks to the surface of the photosensitive drum, it may be that the magnetic roller scraper is aging and deformed, which cannot limit the supply of toner, so the magnetic roller scraper should be replaced.
3. When there is no problem in the above inspection, it is possible that the distance between the developing magnetic roller and the photosensitive drum is too close. General printer maintenance, there should be a certain gap between the photosensitive drum and the magnetic roller to facilitate the toner jumping. Most models maintain the gap by installing isolation sleeves at both ends of the magnetic roller, and the thickness of the isolation sleeve is the standard gap.
Different models have different gaps, generally between 0.2 and 0.4 mm, which will wear the gasket during printing and reduce the gap. Sometimes during maintenance, the isolation sleeve is lost, resulting in no gap.
The method of measuring the gap between the isolation sleeve and the magnetic roller is: test with two layers of 80g printing paper, and insert it smoothly after the gap is correct. If not, replace the isolation sleeve.
