D. Storing and Handling the Cartridge

The cartridge is subject to the effects of the environment whether its packing seal is intact or

removed or whether it is inside the machine or otherwise, changing over time regardless of the

number of copies made. The degree of change is highly dependent on the site of installation and

how it is maintained, and no general rule may be drawn; however, it is important to exercise care

when storing or handling it.

D-1. Storing the Cartridge with the Packaging Seal Intact

If you are storing the cartridge in a warehouse or workshop, be sure that the environment is as

indicated in Table 1-1; in addition, keep the following in mind:

• Avoid direct rays of the sun.

• Avoid vibration.

• Do not subject it to impact (as by hitting or dropping it).

D-2. Storing and Handling the Cartridge with the Packaging Seal

Removed

The photosensitive medium is an organic photoconducting (OPC) material, which would dete-

riorate if subjected to storing light.

The cartridge also holds toner, requiring the user to exercise care when storing or handling it.

(Be sure that the user stores it in an appropriate storage box for storage.)

1. Storage after Removing the Packaging Seal

a. Avoid areas subject to the direct rays of the sun, i.e., near a window. Do not keep it in a car for

a long time, as it will be subjected to an extremely high temperature. (This applies even if the

cartridge is inside a protective box.)

b. Avoid areas subjected to high or low temperature/humidity or where temperature or humidity

tends to change abruptly (e.g., near an air conditioner).

c. Avoid areas subject to dust, ammonium gas, or organic solvent.

d. Make sure that the cartridge is stored at 40°C/104°F or lower.

CHAPTER 1 MAINTENANCE AND INSPECTION

1-4

2. Handling the Cartridge

a. Before setting the cartridge in the machine or if copies have white spots as when it starts to run

out of toner, hold the cartridge level and shake it about 90° several times as shown in Figure 1-

1 to even out the toner inside.

If you shake it in a different way, the toner can spill out of the developing assembly or the

cleaning assembly.

Figure 1-1

b. Do not place the cartridge on its end or turn it over as shown in Figure 1-2.
