Push down the green lock lever and take 
the toner cartridge out of the drum unit.

Handle the toner cartridge carefully. If toner 
scatters on your hands or clothes, wipe or 
wash it off with cold water at once.

To avoid print quality problems, DO NOT 
touch the shaded parts shown in the 
illustrations below.

e

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.
