1. Toner cartridge problem (insufficient powder, aging or hemp damage of toner cartridge accessories)
2. Laser problem (dirty laser)
3. Fusing part (Fusing film worn or damaged)
terms of settlement:
1. Replace the toner cartridge (80% of them are toner cartridge problems)
2. Clean the laser (poor environment or not cleaned for a long time may occur)
3. Press Print * Enter * Print, turn off the printer when the paper goes to the bottom of the toner cartridge, and check whether the effect under the toner cartridge will fade at the same time. If it does not go to the fixing, it is normal, and after the fixing, it will blur. That is the possibility that the fixing film has a problem (10-20%)
