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
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 the Toner Save button on the control
panel; see “Toner Save Mode” on page 2.11. The button
backlight turns on. Using this feature extends the life of the
toner cartridge and reduces your cost per page, but it also
reduces print quality.
Expected 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
cartridge more often.
