Storing Toner Cartridges
Follow these simple guidelines when you handle and store toner cartridges.
Handling Cartridges
½ Do not remove the toner cartridge from its protective bag until you are ready
to install it.
½ Save the protective bag. You may need it later to re-pack the cartridge
temporarily to protect it from exposure to light.
½ 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.
½ 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.
