3) Installation of equipment and storage of drum
Avoid installing the equipment where it may be subjected to high temperature, high humidity, chemi-
cals and/or their fumes.
Do not place the drum in a location where it is exposed to direct sunlight or high intensity light such
as near a window. Otherwise the drum will fatigue, and will not produce sufficient image density
immediately after being installed in the equipment.
4) Cleaning the drum
At periodic maintenance calls, wipe the entire surface of the drum clean using the designated clean-
ing cotton. Use sufficiently thick cleaning cotton (dry soft pad) so as not to scratch the drum surface
inadvertently with your fingertips or nails. Also, remove your rings and wristwatch before starting
cleaning work to prevent accidental damage to the drum.
Do not use alcohol, selenium refresher and other organic solvents or silicon oil as they will have an
adverse effect on the drum.
5) Scratches on photoconductive drum surface
If the surface is scratched in such a way that the aluminum substrate is exposed, no copy image will
be produced on this area. In addition, the cleaning blade will be damaged so replacement with a
new drum will be necessary.
6) Collecting used photoconductive drums
Regarding the recovery and disposal of used photoconductive drums, we recommend following the
relevant local regulations or rules.

- Do not allow hard objects to hit or rub against blade edge.
- Do not rub the edge with a cloth or soft pad.
- Do not leave oil (or fingerprints, etc.) on the edge.
- Do not apply solvents such as paint thinner to the blade.
- Do not allow paper fibers or dirt to contact the blade edge.
- Do not place the blade near a heat source.
2) Cleaning procedure
Clean the blade edge with a cloth moistened with water and squeezed lightly.

vent such as alcohol, and then attach the transfer belt.
