Why Is There A Word On The Rotary Printing Roller Of The Printer?
Details of the problem
In the process of repairing the printer, I found that there are many words stuck on the rotary printing roller of the printer. I understand that the function of the rotary printing roller of the printer is to transfer the words on the selenium drum to the paper through the attraction of different nuclei or the repulsion of the same charge. Why are there words on the transfer? Here are the pictures.
Under normal circumstances, there is paper between the selenium drum and the rotary printing roller, and the carbon powder will not directly contact the rotary printing roller.
What's the effect of the paper you print out?
Possible causes of the problem:
1. The toner cartridge has the function of recovering toner, which may be damaged. You need to confirm the toner cartridge.
2. The paper sensor did not detect the passage of paper. The selenium drum is in direct contact with the rotary printing roller.
One of the most critical is: to see the actual output effect of paper.
