Managing Toner Cartridge

Expected Cartridge Life

The life of your toner cartridge depends on the amount of toner used
in each print job. For instance, when you print a typical business
letter with about 5% page coverage, you can expect a toner cartridge
life of approximately 5,000 pages. (You can check the amount of
printed page by printing a test page. See page 1-6.) The actual number
may vary according to the print density of the page you print. If you
print a lot of graphics, you may need to change the cartridge more
often.
If Econo Mode option is available in your software application
program, you can extend the life of your toner cartridge by using
Econo Mode. Econo Mode uses approximately 50% less toner than
normal printing. The printed image is much lighter, and is adequate
for printing drafts or proofs.

Replacing Toner Cartridge

When the toner cartridge is near the end of its life, white vertical
streaks or hue changes will occur. You can temporarily re-establish
print quality by redistributing the remaining toner in the cartridge.
1. Open the printer cover and remove the toner cartridge.
2. Gently shake the cartridge to distribute the toner evenly inside
the cartridge.
3. Reinstall the cartridge and close the cover.
This is typically successful one time only. When the toner will
eventually run out, print quality problems occur again and the
ERROR light on the operator panel comes on. The toner cartridge
needs to be replaced. See the following page.
