■ 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:

1 Position 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.

3 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.

Note

Do not try to clean the surface of the photosensitive drum with a sharp object.

■ The drum unit may be damaged. Put in a new drum unit. See Replacing the drum

unit on page 5-8.
