LASER CLASS 3170/3175/3175MS Chapter 1: Safety and Precautions
2.2.2 Storing unsealed parts
As an organic photoconductor (OPC) is used in the photosensitive drum, it will
deteriorate if exposed to strong light. As there is also toner in the cartridge, be
sure to explain to the customer the need to be careful in handling and storing
unsealed cartridges.
2.2.3 Storage environment
a) Be sure to store in the protective bag.
b) Avoid locations exposed to direct sunlight, near windows, etc. Do not leave
the cartridge in cars for any extended period of time as heat can damage it.
c) Avoid high, low, and changeable temperature/humidity locations.
d) Avoid sites with corrosive gases (pesticides) or salt in the air.
e) Store the cartridge within a range of 0°C (32°F) to 35°C (95°F).
f) Do not place the cartridge near CRT displays, disk drives, or floppy disks.
g) Store the cartridges out of reach of children.
2.2.4 Effective life
Cartridges are effective for 2.5 years following the date of manufacture, which is
displayed in an abbreviated form on the cartridge. The cartridge life span is also
displayed (month and year) on the cartridge box as 2.5 years from the date of
manufacture. Cartridges should be used within their life spans, as image quality
will deteriorate after the expiry date.
2.2.5 Handling
(1) When loading a new cartridge into the printer, or when blank spots appear
on output images due to uneven distribution of the toner during use, hold
the cartridge at each end as shown in the figure below. Slowly rock it 5 to 6
times at a 45-degree angle to evenly distribute the toner, and reload it into
the printer. Do not shake the cartridge in any other ways, as toner may
leak from the developing cylinder or the cleaning unit.
