Cleaning the drum unit

Dust, paper powder, glue, and so on may stick to t he surface of t he photosensi tive

drum (OPC) and cause black or white spot s to appear on prin ted documents.

Make a few copies of a blank, white sheet of paper. (See Making multiple copies

on page 8-2.)

If you still see the spots on printed documents after making multiple copies, clean

the drum unit as follows :

1 Remove the drum unit and t oner cartridge as sembly, and the n remove the tone r

cartridge from the drum unit.

2 Position the print sample in front of the drum unit so you will know the exact

position on the drum that is causing the poor print.

3 Turn the black gear on th e drum as you chec k the surface of the OPC drum.

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

4 When you find the substance on the drum surface that matches the print

sample, gently dab the surface of the OPC drum with a cotton swab that is lightly

dampened with isopropy l alcohol.

Do not use a scrubbing or wipin g motion because th is might damage the

drum.

Do not try to clean the surfac e of the OPC drum with a s harp object, such as

a ball-point pen, because this might cause permanent damage to the drum

unit.

If the print quality still has not improved you need to install a new drum.

(See Replacing the drum unit (DR-350) on page 11-27.)
