4.7 Precautions for Storing and Handling Supplies
4.7.1 Precautions for storing TOSHIBA supplies
1. Toner/Developer
Toner and developer should be stored in a place where the ambient temperature is between 10C to
35C (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 10C to 35C (no condensation). Be sure to avoid places where
drums may be subjected to high humidity, chemicals and/or their fumes.
3. Drum cleaning blade
This item should be stored in a flat place where the ambient temperature is between 10C to 35C,
and should also be protected against high humidity, chemicals and/or their fumes.
4. Fuser roller / Pressure roller
Avoid places where the rollers may be subjected to high humidity, chemicals and/or their fumes.
5. Paper
Avoid storing 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 photoconductive drum
1. Use of gloves
If fingerprints or oil adhere to the drum surface, the property of the photoconductive drum may
degrade, affecting the quality of the print image. So, do not touch the drum surface with your 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 (the Setting Mode 08-1150-0,3,6,7) must be cleared to 0 (zero).
Notes:
Application of 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.
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 the equipment and storage of drum
Avoid installing the equipment where it may be subjected to high temperature, high humidity,
chemicals and/or their fumes.
Do not place the light drum in a location where it is exposed to direct sunlight or high intensity light
such as near a window. Otherwise the drum will fatigue, and will not produce sufficient image
density immediately after being installed in the equipment.
4. Cleaning the drum
At preventive maintenance calls, wipe the entire surface of the drum clean using the designated
cleaning cotton. Use sufficiently thick cleaning cotton (dry soft pad) so as not to scratch the drum
surface inadvertently with your fingertips or nails. Also, remove your rings and wristwatch before
starting cleaning work to prevent accidental damage to the drum.
Do not use alcohol, selenium refresher and other organic solvents or silicon oil as they will have an
adverse effect on the drum.
5. Scratches on photoconductive drum surface
If the surface is scratched in such a way that the aluminum substrate is exposed, no print image will
be produced on this area. In addition, the cleaning blade will be damaged so replacement with a
new drum will be necessary.
6. Collecting used photoconductive drums
Regarding the recovery and disposal of used photoconductive drums, we recommend following the
relevant local regulations or rules.

4.7.3 Checking and cleaning of drum cleaning blade
1. Handling precautions
Pay attention to the following points as the cleaning blade life is determined by the condition of its
edge:
- Do not allow hard objects to hit or rub against blade edge.
- Do not rub the edge with a cloth or soft pad.
- Do not leave oil (or fingerprints, etc.) on the edge.
- Do not apply solvents such as paint thinner to the blade.
- Do not allow paper fibers or dirt to contact the blade edge.
- Do not place the blade near a heat source.
2. Cleaning procedure
Clean the blade edge with a cloth moistened with water and squeezed lightly.
4.7.4 Checking and cleaning of fuser roller and pressure roller
1. Handling precautions
- Fuser roller
Do not leave any oil (fingerprints, etc.) on the fuser roller.
Be careful not to allow any hard object to hit or rub against the fuser roller, or it may be damaged,
possibly resulting in poor cleaning.
- Pressure roller
Do not leave any oil (fingerprints, etc.) on the pressure roller.
2. Checking
- Check for stain and damage on the fuser and pressure rollers, and clean if necessary.
- Check the separation guide and fingers and check for chipped tips.
- Check the thermistors for proper contact with the pressure roller.
- Check the fused and fixed condition of the toner.
- Check the gap between the entrance guide and pressure roller.
- Check the fuser roller for proper rotation.
3. Cleaning procedure
When fuser roller and pressure roller become dirty, they will cause jamming. If this happens, wipe
the surface clean with a piece of soft cloth. For easier cleaning, clean the roller white they are still
warm.
Note:
Be careful not to rub the fuser roller and pressure roller surface with your nails or hard objects
because it can be easily damaged. Do not use silicone oil on the fuser roller and pressure roller.

6.1.2 Writing the data to the download jig (PWA-DWNLD-350-JIG)
The download jig (PWA-DWNLD-350-JIG) is the jig in which the Flash ROM is mounted on the board
directly. The ROM writer adapter (PWA-DL-ADP-350) is required to write data to these Flash ROMs.
Connect the download jig with the ROM writer via ROM writer adapter to write data.
For the procedure to write data, refer to the download procedure, instruction manual of each ROM
writer, or others.
Fig. 6-9
Note:
There are two types of the ROM writer adapter. Use the proper one according to the ROM writer
to be used. Applicable type of the adapter for the ROM writer can be confirmed by the model
name indicated on the board. Confirm that the adapter is available for the ROM writer to be used
before connecting them. If an unapplied adapter is connected, the application of the ROM writer
judges it as an error and writing the data cannot be implemented. Applicable combinations of the
ROM writer and adapter are as follows.

[A] Precaution when writing the data
Set the writing voltage (VID) to 3.3V.
When writing the data, set the address from 0 to 1FFFFF. The data may not be written correctly if it
is not set.
The Flash ROM in which the data will be written, on the download jig is selected by switching the
rotary switch on the adapter. Be sure to switch the rotary switch on the adapter depending on the
data (file) to be written.
Important:
When an error such as "Over current detects" appears while the data are being written to the
download jig and the writing cannot be finished, set the writing voltage (VID) to 12 V and then
write them.
Note:
Be sure not to confuse different ROM Versions since the file name is identical although the ROM
version is different.
