Troubleshooting and routine maintenance
CAUTION
■
Brother strongly recommends that you
do not refill the toner cartridge provided
with your MFC. We also strongly
recommend that you continue to use
only Genuine Brother Brand
replacement toner cartridges (TN-350).
Using or attempting to use potentially
incompatible toner and/or toner
cartridges in your MFC may cause
damage to the machine itself and/or it
may result in unsatisfactory print
quality. Our warranty coverage does
not apply to any problem that was
caused by the use of unauthorized
third party toner and toner cartridges.
To protect your investment and
guarantee your print quality please
continue to replace consumed toner
cartridges with only Genuine Brother
Branded Supplies.
■
Wait to unpack the toner cartridge until
immediately before you install it in the
MFC. If a toner cartridge is left
unpacked for a long period of time, the
toner life is shortened.
■
Do not touch the shaded parts shown
in the illustrations to prevent any
degradation to the print quality.
