C. Notes for Storing and Handling the EP Cartridge
The cartridge can be affected by the environment and change over time whether it is still sealed
in the box or installed in the printer, regardless of the number of prints. Since the pace at which
it changes depends on the installation and storage environments, be very careful in storing and
handling the cartridge.
1. Storing the sealed cartridge
When storing in a warehouse or workshop (service depot), note the following:
1) Avoid areas exposed to sunlight.
2) Avoid areas that are subject to vibration.
3) Do not bump or drop it.
2. Storing the unsealed cartridge
A cartridge contains a photosensitive drum coated with an organic photoconductor (OPC) that
deteriorates when exposed to strong light. Advise the customer the correct storing and handling
of the cartridge.
a. Storage precautions
1) Always store the cartridge in its protection bag.
2) Avoid areas exposed to sunlight or near windows. Do not leave a cartridge in a car for a long
time, as the inside of the car can get extremely hot.
3) Avoid areas that get extremely hot and humid or extremely cold and dry. Also, avoid areas
where the temperature can change suddenly.
4) Avoid dusty areas, or areas filled with ammonia or organic solvent gas.
5) Store the cartridge in the temperature range 0 to 35 ˚C.
6) Keep cartridges away from computer CRT displays, disk drive devices, and floppy disks.
7) Keep the cartridge out of reach of children.
b. Handling precautions
1) Before installing a new cartridge in the printer, hold the cartridge horizontally and slowly
rock it 45 degrees each way about the drum axis, five or six times, to distribute the toner
evenly as shown in the illustration below.
Rocking it any other way may result in toner leaking from the developing cylinder or clean-
ing unit.
After installing a new cartridge, print three to five test patterns to check for toner leakage.
2) Before transporting the printer, remove the cartridge.
