Maintaining the toner 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 toner cartridge.
•Store toner cartridges in the same environment as your machine.
•To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes.
Saving toner
To save toner, press 
button until Toner Save appears and
then press 
button when On appears. Using this feature extends the life of the toner cartridge and reduces your cost per page, but it also reduces print quality.
Expected toner cartridge life
The life of the toner cartridge depends on the amount of toner that print jobs require. When printing text at ISO 19752 5% coverage, a new toner cartridge lasts an average of 3,000 pages. (The original toner cartridge supplied with the machine lasts an average of 1,000 pages.) The actual number may be different depending on the print density of the page you print. If you print a lot of graphics, you may need to change the toner cartridge more often.
NOTE: The 1,000 pages and 3,000 pages toner cartridge have different shapes.
Redistributing the toner cartridge
When the toner cartridge is near the end of its life:
•White streaks or light printing occurs.
•The warning message, Toner Low displays on the control panel.
•The Smart Panel program window appears on the computer telling you that the toner cartridge is low on toner.
•The Status LED blinks red.
If this happens, you can temporarily reestablish print quality by redistributing the remaining toner in the toner cartridge. In some cases, white streaks or light printing will still occur even after you have redistributed the toner.

Maintenance
2Pull the toner cartridge out.
3Thoroughly roll the toner cartridge 5 or 6 times to distribute the toner evenly inside the toner cartridge.
NOTE: If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into fabric.
CAUTION: Do not touch the green underside of the toner cartridge. Use the handle on the toner cartridge to avoid touching this area.
4Hold the toner cartridge by the handle and slowly insert the toner cartridge into the opening in the machine.
5Tabs on the sides of the toner cartridge and corresponding grooves within the machine will guide the toner cartridge into the correct position until it locks into place completely.
6Close the front cover. Make sure that the cover is securely closed.
