4) Open the hopper, and release the feeding assembly.
5) Remove the mounting screw
Note:
Take care not to damage the photosensitive drum.
Note:
The photosensitive drum is very susceptible to light, and exposure to even room
lighting can cause copies with white spots or black bands.
As a rule, do not turn on the power after removing the drum unit; otherwise, the
following may occur:
• The registration roller and the transfer guide may interfere with each other; the
rotation of the registration roller during WMUPR will damage the roller.

2. Cleaning

If the surface of the photosensitive drum has become soiled, wipe it with a flannel
cloth (not paper, lint-free or otherwise) coated with toner.
Note:
Do not dry wipe or clean with solvent.
Do not use drum cleaning powder.
