D. Storing, Handling the EP-72 Cartridge
Whether the cartridge is still sealed in its box or installed in the printer, the effect of the natur-
al environment will change it over time regardless of the number of prints. As the progression of
this natural change depends on the storage or installation environment, take sufficient care in
storing and handling the cartridges.
1. Before unsealing the box
When the cartridge is stored in a warehouse, workshop, etc., be sure to keep it within the ranges
shown in Table 1-5-1. Note the following points:
1) Avoid locations in direct sunlight.
2) Do not leave in areas exposed to strong vibration.
3) Do not bump or drop.
Table 1-5-1 Storage temperature and humidity conditions
Note: Total storage time is the valid time span following the manufacture date displayed on
the cartridge box.
2. After unsealing the box
As an organic photoconductor (OPC) is used in the photosensitive drum, it will deteriorate if
exposed to strong light. As there is toner in the cartridge, be sure to explain to the customer the
need to be careful in handling and storing unsealed cartridges.
a. Storage environment
1) Be sure to store in the aluminum bag.
2) Avoid locations exposed to direct sunlight, near windows, etc. Do not leave them in cars for
any extended period of time as heat can damage the cartridges.
3) Avoid high, low, and changeable temperature/humidity locations.
4) Avoid sites with corrosive gases (pesticides) or salt in the air.
5) Store the cartridge within a range of 0 to 35°C.
6) Do not leave cartridges near CRT displays, disk drives or floppy disks.
7) Store the cartridges out of reach of children.
