To solve this problem, try to print a few pages. If the problem still occurs after printing a few pages, the drum unit may have glue from a label stuck on the OPC drum surface.


Clean the drum unit as follows:

1. Put the print sample in front of the drum unit, and find the exact position of the poor print.

2. Turn the drum unit gear by hand while looking at the surface of the OPC drum (1).

3. When you have found the mark on the drum that matches the print sample, wipe the surface of the OPC drum with a dry cotton swab until the dust or glue on the surface comes off.

If the problem still occurs even after you have cleaned the drum unit, the drum unit may be damaged. Put in a new drum unit. To see how to see replace the drum unit, click here.
