Maintaining the print cartridge
Print cartridge storage
To get the most from the print cartridge, keep the following guidelines in mind:
•Do not remove the print cartridge from its package until ready for use.
•Do not refill the print cartridge. The printer warranty does not cover damage caused by using a refilled cartridge.
•Store print cartridge in the same environment as the printer.
•To prevent damage to the print cartridge, do not expose it to light for more than a few minutes.
Expected cartridge life
The life of the print cartridge depends on the amount of toner that print jobs require. The actual number may also be different depending on the print 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 in the print cartridge
When the print cartridge is near the end of its life span:
•White streaks and light printing occur.
•The Status Monitor program window appears on the computer.
•The Error LED blinks red.
If this happens, you can temporarily reestablish print quality by redistributing the remaining toner in the cartridge. In some cases, white streaks or light printing will still occur even after you have redistributed the toner.
