2. Cleaning the Drum
Caution:
As a rule, do not touch or clean the photosensitive drum.
1) Open the machine's top unit, and take out the cartridge.
2) Turn over the cartridge, and open the drum cover shutter
3) Clean the drum surface with a flannel cloth coated with toner.
Caution:
1. If you need to rotate the drum, be sure to rotate it in the direction in which it rotates when
making copies. Otherwise, the leaf spring used to apply a developing bias to the develop-
ing cylinder will develop poor contact.
2. If you must clean it, use a flannel cloth. Do not use paper, lint-free or otherwise.
3. If exposed to light for an appreciable time, the images will be affected. Be sure to work
briskly.
Reference:
If the photosensitive drum is exposed to light of 1500 lux (ordinary lighting) for 5 min and
then is left alone for 5 min in a dark place, it will recover to a level at which it will cause no
practical problem.
However, avoid exposing it to direct sunlight. The rays of the sun are usually about 10000 to
30000 lux.
