Toner Cartridge Issues
Replacing the Toner Cartridge
The number of pages you can print with one toner cartridge
varies depending on the type of documents you usually
receive or copy. A toner cartridge will print about 2,000
letter-size pages at a typical print coverage of 4% (equivalent
of CCITT No. 1 test chart).
!
The first toner cartridge in your new fax machine has
to fill the drum reservoir and saturate the developing
roller with toner. For this reason, it will need to be
replaced sooner than subsequent cartridges—after
about 1,000 pages.
If your fax machine displays
TONER LOW or REPLACE
TONER CART., replace the toner cartridge with a new one
soon. If print density is high enough, you can continue to use
the toner cartridge without replacing it until print quality
becomes unacceptable. Keep in mind that if you don’t
replace the cartridge soon, there is a risk that a fax will be
unreadable when it prints using an empty cartridge.
If the print density becomes low even before your fax
machine displays
TONER LOW or REPLACE TONER CART.,
gently wipe the lens surface of the LED array (refer to Step 8).
If the print density does not improve, replace the toner
cartridge.
!
Warning: Be careful when handling the toner cartridge.
Do not let toner spill on your clothing or other porous
materials. Use cold water to clean up spilled toner; hot
water causes the stain to set.
