5. STORAGE AND HANDLING OF EP-ED CARTRIDGES
An EP-ED cartridge is influenced by the storage conditions even if it is sealed in its package,
so its life depends on the way in which it is used or stored. EP-ED cartridges should be
handled carefully.
5.1 Storage of Sealed EP-ED Cartridges
When storing sealed EP-ED cartridges in a warehouse or workshop, the storage conditions
shown in (25) Environmental conditions on Page 1-5 must be met. Follow the instructions
below:
1) Avoid direct sunlight.
2) Do not store cartridges on a surface that is subject to vibration.
3) Do not hit or drop the packages containing cartridges.
4) The cartridges should be stored horizontal when they are removed from the body (with
their label side upside).
5) Avoid putting the cartridges near a CRT screen, a disk or a floppy disk (to keep their data
from being destroyed).
5.2 Storage of Unsealed EP-ED Cartridges
Each EP-ED cartridge contains a photosensitive drum that has an organic photoconductor
(OPC) which deteriorates when exposed to strong light. It also contains toner. The user,
therefore, should be fully informed about the correct storage and handling of EP-ED
cartridges.
(1) Storage requirements
1) Avoid places exposed to direct sunlight or near a window. Do not leave an EP-ED
cartridge in a car in warm or hot weather even if it is in its storage box.
2) Avoid places with a too-high or too-cool temperature and/or humidity. Also avoid
places exposed to sudden temperature or humidity changes (such as near an air
conditioner outlet).
3) Avoid dusty places or places exposed to ammonia fumes or other harmful fumes.
4) Do not store an EP-ED cartridge in a temperature above 40°C.
(2) EP-ED cartridge life
The effective life of an EP-ED cartridge is 2.5 years from the date of manufacture
(printed on the cartridge.) The expiry year and month (date of manufacture plus 2.5
years) is shown on the EP-ED cartridge box. An EP-ED cartridge used after the expiry
may produce low-quality printing, so a cartridge should be used within the stated
period.
