Points to Note When Handling the Photosensitive Drum after Installation
The copier's photosensitive drum is highly susceptible to light; mere exposure to
room light can affect the drum enough to produce white spots or black lines on the
copies. Keep the following in mind:
• Do not spend more than 5 min when removing jams.
• After detaching the drum unit from the copier during servicing work, be sure to
protect it in the light-blocking sheet that came with the drum or fresh copy paper,
and place the drum in a dark place.
Do not touch the photosensitive drum or primary charging roller.
If you have soiled the surface of the drum inadvertently, wipe it using a flannel cloth
coated with toner; do not use paper, lint-free or otherwise.
Do not dry wipe or use solvent to clean the drum.
