White spots on black text and graphics or black spots appear at 75 mm (3.0 in.) intervals.
If the problem is not solved after printing a few pages, the drum unit may have glue from label stock on the OPC drum surface.
Clean the drum unit as follows:
-
Position the print sample in front of the drum unit, and find the exact position of the poor print.
-
Turn the drum unit gear by hand while looking at the surface of the OPC drum.
-
When you have located the mark on the drum that matches the print sample, wipe the surface of the OPC drum with a cotton swab until the dust or paper powder on the surface comes off.
Do not try to clean the surface of the photosensitive drum with a sharp object.
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 replace the drum unit, click here.
