Maintaining the cartridge

Toner cartridge storage

To get the most from the toner cartridge, keep the following guidelines in
mind:
• Do not remove the toner cartridge from its package until ready for use.
• Do not refill the toner cartridge. The machine warranty does not cover
damage caused by using a refilled cartridge.
• Store toner cartridges in the same envir onment as your machine.
• To prevent damage to the toner cartridge, do not expose it to light for
more than a few minutes.

Expected cartridge life

The toner cartridge yield depends on the amount of toner that print jobs
require. Average yield for a new toner cartridge is 2,000 standard pages
in accordance with the ISO/IEC 19752 standard. (Average yield for the
original toner cartridge supplied with the machine is 1,000 standard
pages.) The actual number may al so be different depending on the prin t
density of the pages you print on, and the number of pages may be
affected by operating environment, printing interval, media type, and
media size. If you print a lot of graphics, you may need to change the
cartridge more often.
Redistributing toner
When a toner is low the toner LED( ) blinks slowly.
It may cause faded or light areas on a paper. You can temporarily improve
print quality by redistributing the toner.
For detailed information about error message, see page 9.7.
Note
In some cases, white streaks or light printing will still occur even
after you have redistributed the toner.
