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. So, if any fibers are
found adhering to the blade, be sure to remove them carefully using a soft pad.
(3) Installation of Machine and Storage of Drum
Avoid installing the machine in such places where it may be subjected to high temperature, high
humidity, chemicals and their fumes.
Do not leave drums in a bright 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 clean the entire surface of the drum using the designated
cleaning cotton. Use a sufficient thickness of cleaning cotton so as not to scratch the drum
surface inadvertently with your fingertips or nails. Also, remove your ring and wristwatch before
starting cleaning work to prevent accidental damage to the drum.
Be sure not to use alcohol, selenium refresher and other organic solvents or silicone oil as they
will have an undesirable effect on the drum.
(5) Scratches on OPC Drum Surface
If a scratch exists on the surface through which the aluminum substrate can be seen, no copy
image will be produced on this area and, 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, it is recommended to follow the relevent
local regulations or rules.
