White Spots on black text and graphics at 75 mm (2.95 in.) intervals and Black Spots at 75 mm (2.95 in.) intervals.
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:
- Put 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 (1).
- 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.
DO NOT 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 see replace the drum unit, click here.
