7.6 Precautions for Storing and Handling Supplies
7.6.1 Precautions for storing TOSHIBA supplies
1. Toner / Developer
Toner and developer should be stored in a place where the ambient temperature is between 10°C to
35°C (no condensation), and should also be protected against direct sunlight during transportation.
2. 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.
3. 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.
4. Fuser roller / Pressure roller / Cleaning web / 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.
5. 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.
7.6.2 Checking and cleaning of photoconductive 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 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, reset
the drum counter in the PM Support mode (6S).
Then perform "Image quality control enforcement" in the Adjustment mode (05-2120).
Notes:
• Application of 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.
• 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 Copier and Storage of Drum
Avoid installing the copier where it may be subjected to high temperature, high humidity, chemicals
and/or their fumes.
Do not leave drums in a brightly lit 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.
