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.
Do not touch the photosensitive drum with your fingers.
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.
Do not try to clean the surface of the photosensitive drum with a
sharp object. (e.g. ball-point pen, paper clip etc.)
The drum unit may be damaged. Put in a new drum unit. (See Replacing
the drum unit on page 12-30.)
