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

f

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

g

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.

CAUTION

The drum is photosensitive so DO NOT 
touch it with your fingers.

DO NOT clean the surface of the 
photosensitive drum with a sharp object.

DO NOT use a scrubbing or wiping motion 
because this might damage the drum.

Put the toner cartridge back into the 
drum unit until you hear it lock into place. 
If you put the cartridge in properly, the 
green lock lever will lift automatically.

Put the drum unit and toner cartridge 
assembly back in the machine.

j

Close the front cover.
