1.1.4.5 Storing After Unpacking the Cartridge 0007-3484
The photosensitive medium is made of organic photo-conducting material (OPC), and will deteriorate if exposed to
strong light. It is also used to hold toner inside it. Be sure to advise the user to be fully careful when storing and
handling the cartridge. (The cartridge must always be put inside a protective bag for storage.)
a. Use a protective bag for storage.
b. Avoid areas subject to direct sunshine (e.g., near a window). Do not leave it alone inside a card, as the temperature
can rise to an extremely high level. (These are also true even if the cartridge is put in a protective bag.)
c. Avoid areas subject to high temperature/humidity or low temperature/humidity, areas subject to rapid changes in
temperature or humidity, or areas subject to condensation (e.g., near an air conditioner).
d. Avoid areas exposed to corrosive gas (e.g., insecticide) or salty air.
e. Avoid areas subject to dust, ammonium gas, or organic solvent gas.
f. Avoid areas near a CRT display, disk drive, and floppy disk. (The magnetism from the cartridge can destroy the
data.)
g. Keep it out of reach of children.
h. Keep the temperature between 0 and 35 deg C (32 deg and 95 deg F).
1.1.4.6 Effective Period of the Cartridge 0007-3526
The cartridge remains good for about 2.5 yr after the date of manufacture, indicated on the cartridge using an
abbreviation. For the user, the effective period (month, year; 2.5 yr after the date of manufacture) is indicated on the
cartridge package and the unit package. It is best to use up the cartridge within the effective period, after which the
image quality may be adversely affected.
1.1.4.7 Points to Note When Handling the Cartridge 0007-3485
a. When fitting the cartridge to the machine, on if white spots start to occur in copy images caused by decreasing
toner, hold the cartridge level as shown in following figure, and rock it about 90 deg to both sides 5 to 6 times,
thereby evening out the toner inside it. Do not shake the cartridge in ways not indicated; otherwise, toner can start
to leak from the cleaner assembly.
