13. Remove the photoreceptor drum. (See page 130).
14. Place the photoreceptor drum on a covered work surface.
15. If the drum is only slightly dirty, clean it with ethanol or isopropyl
alcohol. Do not use acetone.
CAUTION
When cleaning the photoreceptor drum, note the following:
•Do not touch the drum surface with your hands.
•To prevent the drum surface from being scratched, clean it
in a location free of dust.
•Cleaning the drum may result in stains. A drum left unused
in the printer for a long time after cleaning may especially
be affected. Therefore, after cleaning and installing the
drum in the printer, use maximum size paper to print an
image repeatedly until no stains remain. Stains will usually
be cleared after printing a few dozen pages.
•Press lightly when polishing the drum surface, as too
much pressure can damage the drum.
16. If the drum contains toner build-up, clean it with the drum
freshener pad (listed on page 152). Turn the drum little by littl e
while polishing the drum surface with the freshener pad. Polis h
with a slight force in the direction of the drum axis, using a
circular motion. Let the polished areas slightly overlap eac h
other, and polish the entire drum surface two or three times
repeatedly.
17. Using the special dry tissue paper (listed on page 152),
thoroughly wipe the drum freshener off the drum surface.
18. Wipe the drum surface again using a Toraysee cloth.
