Figure 6-613
Caution:
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 copy paper),
and keep it in a dark place.
Figure 6-614
Reference:
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.)

Photosensitive Drum
When installing a new photosensitive
drum, perform the following:
1) Mount the new photosensitive drum.
