7.10.5 Photosensitive Drum

7.10.5.1 Points to Note When Handling the
Photosensitive Drum
The machine's photosensitive drum is made of high-sensitivity
amorphous silicon, and its sensitivity can start to deteriorate depending
on how and where it is placed, requiring the following:
1. Whenever the process unit is removed from the machine or the
photosensitive drum is removed from the process unit, be sure to
protect the photosensitive drum against light. Use the photosensitive
drum protective sheet or wrap six or more sheets of A3 or larger
paper.
2. Do not place the process unit or the photosensitive drum in an area
subject to the direct rays of the sun.
3. Do not place the process unit or the photosensitive drum in an area
subject to high or low temperature or humidity or where temperature
or humidity tend to fluctuate rapidly.
4. Do not place the process unit or the photosensitive drum in an area
subject to dust, ammonium gas, or organic solvent/gas.
The foregoing requirements commonly apply to all photosensitive
drums.
