Cleaning The Photoreceptor Drum
CAUTION When cleaning the photoreceptor drum, observe the following
precautions:
• 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 wiping 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 usually clear after printing a few dozen
pages.
1. Remove the photoreceptor drum from the printer. (See page
115.)
2. Place the drum on a covered work surface.
3. If the drum is only slightly dirty, clean it with ethanol or isopropyl
alcohol. Do not use acetone.
4. If the drum has toner buildup, clean it with the drum freshener
pad. (See page 136.) Turn the drum little by little while polishing
the drum surface with the freshener pad. Polish with a slight
force in the direction of the drum circumference, using a
circular motion. Let the polished areas slightly overlap each
other, and polish the entire drum surface two or three times.
CAUTION Press lightly when polishing the drum surface, as too much
pressure can damage the drum.
5. Using the special dry tissue paper (see page 136), thoroughly
wipe the drum freshener off the drum surface.
6. Wipe the drum surface again using a Toraysee cloth. (See
page 136.)
