PRECAUTIONS FOR STORING & HANDLING SUPPLIES
3 - 4 December 2002 TOSHIBA TEC
3.6 Checking and Cleaning of the Photoconductive Drum
(1) Use of gloves
Since fingerprints or oil stains on the drum surface affects the quality of the copy image and degrades
the characteristics of the photoconductor, do not touch the drum surface with your bare hands.
(2) Handling precautions
As the drum surface is very sensitive, be sure to handle the drum carefully when installing or removing
it so as not to damage its surface.
When the drum is replaced with a new one, apply patting powder (lubricant) on the entire surface of
the new drum (including both edges to where the OPC is not coated) and separation claw of the
cleaner before installing them. The drum counter must be cleared to 0 (zero) in the setting mode 08-
673.
Notes: 1. Application of the patting powder is to reduce friction among the drum, the cleaning blade and
the separation claw. If this process is not performed, the drum and the cleaning blade may be
damaged.
2. Remove any fibers or lint adhering to the blade since they can damage the drum and blade, or
allows defective cleaning.
(3) Installation of the copier and storage of the drum
Do not install the copier in a place where it may be exposed to high temperature, high humidity,
chemicals and/or chemical gas.
Do not leave the drum in a brightly lit place for a long time. Otherwise, it would be fatigued and causes
background fogging on the copied image right after it is installed in the machine. However, this phe-
nomenon will decrease as time elapses.
(4) Cleaning the drum
At the preventive maintenance, wipe the entire surface of the drum softly using the specified cleaning
cotton (dry soft pad). Use sufficiently thick cleaning cotton so as not to touch the drum surface directly
with your fingertips or nails. Remove your rings and wristwatch before cleaning so as not to damage
the drum.
Do not use organic solvents such as alcohol or silicone oil as they have a bad influence on the drum.
Do not use selenium refresher either.
(5) Scratches on the photoconductive drum surface
If the surface is scratched and the aluminum base is exposed, black spots or streaks will appear on
the copied images. Since those scratches can damage the cleaning blade, replace the drum with a
new one.
(6) Used photoconductive drums
Dispose of the used drums following the regulations regarding industrial waste established by your
local municipal office.
