the bottom (i.e., the drum heater friction
plate is at the bottom).
Figure 6-613
The photosensitive drum is
susceptible to light, and
exposure to light for a long
time can lead to white spots
or black bands on copies.
Whenever you have
removed the photosensitive
drum from the copier, wrap
it with the light-blocking
sheet (or five to six sheets
of fresh paper), and keep it
in a dark place.
Figure 6-614
REF.
If the photosensitive drum
is exposed to light of 600
lux for 1 min and is kept in
a dark place for 24 hr
thereafter, it may recover
to more or less normal
condition (not affecting
actual copies).
Nevertheless, take care not
to subject it to direct
sunlight. (Rays of the sun
typically are 10000 to
30000 lux.)
