4.8 Precautions for Storing and Handling Supplies
4.8.1 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) Photoconductive drum
Like the toner and developer, photoconductive 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.
3) Drum cleaning blade / Transfer belt cleaning blade
This item should be stored in a flat place where the ambient temperature is between 10°C to 35°C,
and should also be protected against high humidity, chemicals and/or their fumes.
4) Transfer belt / Transfer roller / Fuser belt / Pressure roller
Avoid places where the rollers may be subjected to high humidity, chemicals and/or their fumes.
5) Oil roller / Cleaning roller
Avoid places where the rollers may be subjected to high humidity, chemicals and/or their fumes.
They should also be stored “horizontally” on a flat surface.
6) 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.
4.8.2 Checking and cleaning of photoconductive drum
1) Use of gloves
If fingerprints or oil adhere to the drum surface, the property of the photosensitive drum may
degrade, affecting the quality of the copy image. So, do not touch the drum surface with bare hands.
2) Handling precautions
As the photoconductive 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 (including both ends of
the drum where OPC is not coated) when replacing the drum. When the drum has been replaced
with a new one, the drum counter (setting mode (08-1150-0, 3, 6 and 7) must be cleared to 0 (zero).
This clearing can be performed in PM support mode.
Notes:
1. Application of the patting powder is for reducing the friction between the drum and cleaning
blade. If the application of patting powder is neglected, the drum and cleaning blade may be
damaged.
2. When paper fibers or dint 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.
