PREVENTIVE MAINTENANCE (PM)

Checking and cleaning of photoconductive drum
1) Use of gloves
If fingerprints or oil adhere to the drum surface, the property of the photoconductive drum may
degrade, affecting the quality of the print image. So, do not touch the drum surface with your bare
hands.
2) Handling precautions
As the photoconductive drum surface is very sensitive, be sure to handle the drum carefully when
installing and removing it so as not damage its surface.
Be sure to apply “patting powder” (lubricant) to the entire surface of the drum (including both ends of
the drum where OPC is not coated) when replacing the drum. When the drum has been replaced
with a new one, the drum counter (the Setting Mode 08-1150-0,3,6,7) must be cleared to 0 (zero).
Notes:
• Application of patting powder is for reducing the friction between the drum and cleaning blade.
If the application of patting powder is neglected, the drum and cleaning blade may be dam-
aged.
• When paper fibers or thread 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.
3) Installation of the 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 light 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 den-
sity immediately after being installed in the equipment.
4) Cleaning the drum
At preventive 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 photoconductive drum surface
If the surface is scratched in such a way that the aluminum substrate is exposed, no print 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.
