(3) Installation of Copier and Storage of Drum
Avoid installing the copier where it may be subjected to high temperature, high humidity, chemicals
and/or their fumes.
Do not leave drums in a brightly lit place for a long time. Otherwise the drum will fatigue, and will not
produce sufficient image density immediately after being installed in the machine. However, this
effect may decrease as time elapses.
(4) Cleaning the Drum
At periodic maintenance calls, wipe the entire surface of the drum clean using the designated cleaning
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 OPC 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 OPC Drums
Regarding the recovery and disposal of used OPC drums, we recommend following the relevant local
regulations or rules.

(1) Handling precautions
Pay attention to the following points as the cleaning blade life is determined by the condition of its
edge:
• 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 loose thread or dirt to contact the blade edge.
• Do not place the blade near a heat source.
2. When paper fibers adhere to the cleaning blade edge, they may reduce the cleaning efficiency
and, in addition, may damage the blade and the drum. Be sure to remove any fibers found
adhering to the blade.
