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.
