c. Removing the Photosensitive Drum
Points to Note When Handling the Photosensitive Drum
The machine's photosensitive drum is made of high-sensitivity amorphous
silicon, and thus its sensitivity can deteriorate if it or the process unit is not
placed properly. When handling the process unit or the photosensitive
drum, keep the following in mind:
1. If you have removed the process unit from the machine, protect the pho-
tosensitive drum from light by using the photosensitive drum protection
sheet or by wrapping 6 or more A3 or larger sheets.
2. Do not place the process unit or the photosensitive drum in an area ex-
posed to direct rays of the sun.
3. Do not place the process unit or the photosensitive drum in an area sub-
ject to high temperature/humidity or low temperature/humidity or rapid
changes in temperature or humidly.
4. Do not place the process unit or the photosensitive drum in an area sub-
ject to dust, ammonium gas, or organic solvent gas.
The foregoing equally holds true for the photosensitive drums of all mod-
els.
1) Remove the developing fan. (See
8.4.3.m.)
2) Slide out the process unit. (See 5.8.1.a.)
3) Remove the 3 screws [1], and discon-
nect the 2 connectors [2]; then, detach
the sub plate assembly [3].
