If you have print quality problems, clean the drum unit as follows:

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

Fig. 3-8

(2) Turn the drum unit gear to the direction of the arrow of the figure by hand while looking at

the surface of the exposure drum.

Fig. 3-9

(3) When you have found the mark on the drum that matches the print sample, wipe the

surface of the exposure drum with a dry cotton swab until the dust or glue on the surface
comes off.

Fig. 3-10

CAUTION :

• DO NOT clean the surface of the photosensitive drum with a sharp object.
