Photoconductor Unit
Prepare a new photoconductor unit for replacement when you
see a message informing you to do so.
Handling precautions
Note the following handling precautions before replacing the
photoconductor unit:
❏
The photoconductor unit weighs 4.5 kg (9.9 lb). Be sure to hold
it firmly by the handle when carrying it.
❏
When replacing the photoconductor unit, avoid exposing it
to room light any longer than necessary.
❏
Be careful not to scratch the surface of the drum. Also, avoid
touching the drum, since oil from your skin may permanently
damage its surface and affect print quality.
❏
To get the best print quality, do not store the photoconductor
unit in an area subject to direct sunlight, dust, salty air, or
corrosive gases (such as ammonia). Avoid locations subject to
extreme or rapid changes in temperature or humidity.
