The machine's photosensitive drum is a high-sen-
sitivity amorphous silicon drum, whose sensitivi-
ty tends to deteriorate if not handled properly. Be
sure to observe the following whenever handling
the process unit or the photosensitive drum:
1. If you have removed the process unit, be sure
to protect the photosensitive drum against light
by covering it with its protective sheet or
wrapping it with 6 or more sheets of A3 paper.
2. Do not place the process unit or the
photosensitive drum near a window or an area
subject to direct rays of the sun.
3. Do not store the process unit or the
photosensitive drum in a place subject to high/
low temperature/humidity to a rapid change in
these environmental conditions.
4. Do not store the process unit or the
photosensitive drum in a place subject to dust,
ammonium gas, or organic solvent gas.
The foregoing rules equally apply to all types of
