B. Storage and Handling of EP-22 Cartridge
As time passes, the natural environment will change the cartridge, whether sealed or installed
in the printer, or regardless of the number of prints. The progression of this natural change
depends largely on the storage and installation environment, therefore, take special care on stor-
age and handling the cartridge.
a.
Storage of Sealed EP-22 Cartridge Package
When storing EP-22 cartridge in warehouses or workshops, be sure that they are kept within
humidity/storage conditions range shown in Table 1-5-1.
Also note the following:
1) Avoid areas exposed to direct sunlight.
2) Do not place them in locations which are subject to severe vibration.
3) Do not bump or drop the cartridge.
4) Avoid high temperature environment, keep EP-22 cartridge below 35 °C.
Table 1-5-1
Note:
Total storage time is the valid time span following the manufacture date displayed on
the cartridge box.
b. Storage of Unsealed EP-22 Cartridge
Since an organic photoconductor (OPC) is used for the photosensitive drum, intensive light will
damage the drum. It is necessary to thoroughly explain to customers the various storage and
handling procedures of unsealed cartridges.
Note the following:
1) Avoid areas which are exposed to direct sunlight such as near windows. Avoid leaving the
packages in cars for an extended period of time as high temperatures can damage them.
2) Avoid high temperature and high humidity, and low temperature and low humidity environ-
ment. Avoid areas where the temperature or humidity drastically change such as a location
near air conditioners.
3) Avoid dusty areas or locations which emit ammonia or organic solvent gases.
4) Keep EP-22 cartridge below 35 °C
5) Avoid placing the package near CRT displays, disk drive units, or floppy disks.
