Cleaning the drum unit

C

a

Take out the drum unit and toner 
cartridge assembly, and then take out 
the toner cartridge from the drum unit.

b

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

c

Turn the white gear on the drum as you 
check the surface of the OPC drum (1).

d

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 OPC drum is photosensitive so do not 
touch it with your fingers.

Do not use a scrubbing or wiping motion 
because this might damage the drum.

DO NOT clean the surface of the OPC 
drum with a sharp object, such as a ball-
point pen, because this might cause 
permanent damage to the drum unit.
