4. 7. 1.
Precautions for storing TOSHIBA supplies
A. Toner/Developer
Toner and developer should be stored in a place where the ambient temperature is between 10 to 35°C
(no condensation), and should also be protected against direct sunlight during transportation.
B. OPC drum
Like the toner and developer, OPC drums should be stored in a dark place where the ambient temperature
is between 10 to 35°C (no condensation). Be sure to avoid places where drums may be subjected to
high humidity, chemicals and/or their fumes.
C. Drum cleaning blade/Transfer belt cleaning blade
This item should be stored in a flat place where the ambient temperature is between 10 to 35°C, and
should also be protected against high humidity, chemicals and/or their fumes.
D. Fuser roller/Pressure roller/Cleaning WEB/WEB pushing roller/Cleaning roller (felt)/ Transfer belt/Drum
cleaning brush/Transfer belt cleaning brush
Avoid places where the heat rollers may be subjected to high humidity, chemicals and/or their fumes.
E. Cleaning roller (metal)
Avoid places where the felt roller may be subjected to the high humidity, chemicals and/or their fumes
and keep it in a flat place.
F.
Copy Paper
Avoid storing copy paper in places where it may be subjected to high humidity.
After a package is opened, be sure to place and store it in a storage bag.
4. 7. 2. Checking and cleaning of OPC drum
(1) Use of gloves
If fingerprints or oil adhere to the drum surface, the characteristics of the photosensitive drum may
degrade, affecting the quality of the copy image. So, do not touch the drum surface with your bare
hands.
(2) Handling precautions
As the OPC 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 and separation claws on
the cleaner before installing the drum into the machine. When the drum has been replaced with a new
one, the drum counter (setting mode “08”, code “401”) must be cleared to 0 (zero).
Notes: 1. Application of the patting powder is for reducing the friction between the drum, cleaning blade, and
separation fingers. If the application of patting powder is neglected, the drum and cleaning blade may
be damaged.
