1. Verify if you
installed a NEW, out of the box toner cartridge (TN420 or TN450) from a
sealed foil bag.
When replacing a
toner cartridge, you should install a brand new, out of the box toner cartridge
to reset the toner status. You should NOT install a previously used
cartridge that was already installed into another machine or a TN starter
cartridge that comes with the machine.
cartridges are manufactured with a reset lever that moves when installed into
the machine and automatically triggers the machine to reset the "REPLACE TONER"
indicator. If a used cartridge or a TN starter cartridge is installed into
a machine, it will NOT trigger the machine to reset the toner status.
recommends that customers use only genuine Brother drum units and/or toner
cartridges. Each Brother laser printer is designed to operate at pre-set
temperatures that are matched exactly to each of our individual toner
formulations. Each individual component is designed to work with the other
to ensure quality and reliability. Using non-Brother supplies may affect
the hardware performance, print quality and machine reliability. The
Brother limited warranty does not apply to any problem that is caused by the use
of third-party drum units, toner cartridges, or toner.
2. Verify the drum
unit and toner cartridge assembly is installed correctly:
a. Open the front
cover and remove the drum unit and toner cartridge assembly. Place the
assembly on a piece of paper in case of spilled or scattered toner.
b. Remove the toner
cartridge from the drum by holding down the green lock lever on the left side of
the drum unit and lifting the toner out.
Handle the toner cartridge carefully. If toner scatters on your hands or
clothes, immediately wash it off with cold water.
c. Reinstall the toner
into the drum. Be sure it clicks into place. If you put the toner in
properly, the green lock lever will lift automatically.
d. Reinstall the drum
unit and toner cartridge assembly into the machine and close the front
