Replacing 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 normally prints about 1250 pages/A4
size of standard business communications at a typical print
coverage of 4% (equivalent of CCITT No. 1 test chart). The first
toner cartridge installed in a new image drum unit has a slightly
decreased yield because the image drum unit itself has to be
filled.
If your fax machine displays
REPLACE TONER CART.
, replace
the toner cartridge with a new one. However, if user function
22:NO TONER MEM.RX
is set to off and the print density is
high enough, you can continue to use the toner cartridge without
replacing it until the print density becomes too low. If the print
density becomes low even before your fax machine displays
REPLACE TONER CART.
, gently wipe the lens surface of the
LED array (see Step 6). If the print density does not improve,
replace the toner cartridge. When your fax machine’s display
shows
CHANGE DRUM
, replace the image drum unit.
Warning: Be careful when handling the toner cartridge.
Do not let toner spill on your clothing or other porous
materials. See Safety at the beginning of this User's
Guide.
