[5] Maintenance

1. Scanning glass and rollers
Clean the scanning glass and rollers frequently to ensure that your
transmitted images and copies are of the highest quality.
Open the operation panel (grasp the panel release and pull up), and
wipe the scanning glass, rollers and white backplate with a soft
cloth.
• Make sure that all dirt and stains (such as correcting fluid) are
removed, as dirts and stains will cause vertical lines on transmitted
images and copies.

Grasp the print compartment cover at both sides as shown, and
pull up to open the cover.

Grasp the finger hold on the toner cartridge handle where it is
marked PUSH, and pull the handle out. Rehold the handle and
pull the toner cartridge out of the compartment.
• Place the toner cartridge on a sheet of paper on a level surface.
3
Grasp the tabs on the drum cartridge handle and gently pull the
cartridge out of the machine.
4
Take a sheet of clean paper and roll it into a tube. Roll it tightly so
that the diameter of the holes at each end is less than the thick-
ness of your little finger.
5
Gently wipe the surface of the drum with the rolled-up paper to
remove any particles of toner caked on the drum.
• Do not let the drum surface come into contact with anything other
than the rolled-up paper. Fingerprints, water, alcohol, and other
solvents will damage the drum surface.
• Do not touch the drum surface with the edges of the rolled-up
paper.
