Storing Toner Cartridges
Follow these simple guidelines when you handle and store toner car-
tridges.

Handling Cartridges

❏Do not remove the toner cartridge from its protective bag until you
are ready to install it.
❏Save the protective bag. You may need it later to re-pack the car-
tridge temporarily to protect it from exposure to light.
❏Never expose a toner cartridge to direct sunlight, and do not leave it
exposed to normal room light (about 1,000 lux) for longer than 5
minutes.
❏There are strong magnets inside a toner cartridge. To avoid possible
destruction of valuable data on disks or other media, keep the toner
cartridge away from computer screens, hard disks, floppy disks, or
any other kind of material sensitive to magnetic fields.
❏Never touch or try to open the protective shutter that protects the
light-sensitive drum inside the toner cartridge. If the drum is ex-
posed to light, this can cause printing quality deterioration.
❏Handle the toner cartridge with care. Do not subject it to shock or
vibrations.
❏Always set toner cartridges down with the arrow on the cartridge
facing up.
