Routine maintenance

• To prevent damage to the machine from

static electricity, DO NOT touch the

electrodes shown in the illustration.

d Put the print sample in front of the drum

unit, and find the exact position of the

poor print.

e Turn the drum unit gear by hand while

looking at the surface of the OPC

drum (1).

f 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.

IMPORTANT

DO NOT clean the surface of the

photosensitive drum with a sharp object or

any liquids.
