MAINTENANCE AND SERVICING:
The cartridge is affected by the environ-
ment, regardless of whether it is sealed or
unsealed and installed in the machine or
otherwise. Although the properties of the
cartridge change over time independent of
how many copies have been made, the
degree of care taken for the cartridge affects
how long it may remain stable.

house or workshop, make sure the place is
controlled to the specifications shown in
Table 6-1.
a. Avoid direct rays of the sun.

©. Storing and Handling
Unsealed Cartridges
The photosensitive medium is an organ-
ic photoconductor (OPC), which is extremely
susceptible to light. Since the cartridge also
contains toner, you must be extra careful
when storing or handling the cartridge.
Make sure the user is aware of this fact and
will handle the cartridge with care.
i. Storing Unsealed Cartridges
a. Avoid areas subjected to strong rays of
the sun. Do not keep it in a car even in
a protective box; the inside may become
extremely hot.
b. Avoid areas of high or low temperature/
humidity and areas where these factors
tend to change rapidly (for example,
near air conditioners or heaters).
c. Avoid areas where dust, ammonium
gas, or gases from organic solvents tend
to accumulate.
d. Keep the cartridge in a place 40°C/
104°F or less.
