Handling precautions
If fingerprints or oil adhere to the surface of the drum, its properties may degrade, affecting
the quality of the copy image. So, wear gloves to avoid touching the drum surface with your
bare hands. Be sure to handle the drum carefully when installing and removing it so as not to
damage its surface.
Do not use "patting powder" (lubricant)
Since "patting powder" may affect the initial image if it adheres to the OPC surface, do not
apply it. The friction between the drum and cleaning blade is sufficiently small without it and
no problem would occur even if it is not applied.
Clearing the drum counter
When the drum has been replaced with a new one, the drum counter for the new drum (K, Y,
M, C) must be cleared to 0 (zero). This clearing can be performed in PM support mode.
- Drum counter
Drum (K): 08-6250-0, 3, 6, 7
Drum (Y): 08-6252-0, 3, 6, 7
Drum (M): 08-6254-0, 3, 6, 7
Drum (C): 08-6256-0, 3, 6, 7
Storage location of photoconductive drums
The drum should be stored in a dark place where the ambient temperature is between 10°C
to 35°C (no condensation). Be sure to avoid places where drums may be subjected to high
humidity, chemicals 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.
Cleaning the drum
At periodic maintenance calls, wipe the entire surface of the drum clean using the designated
cleaning cotton. Note that there is no need to clean the surface of the new drum unless there
is a problem. 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.
