The message "Replace Toner" continues to appear
after I replaced the toner cartridge. What can I do?Description of Solution 200000031936
1. Verify you installed a
new, unused genuine Brother toner cartridge (TN420 or TN450) from a sealed foil
bag that had never been installed in this or any other machine.
When replacing the toner
cartridge, you MUST install a brand new, unused genuine Brother toner cartridge
in order to reset the toner status. Do NOT install a previously used
cartridge that was already installed into another machine or a TN starter
cartridge that comes with the machine.
Our toner cartridges are
manufactured with a reset lever that moves when installed into the
machine. The movement of the lever mechanically triggers the machine to
reset the toner status. If a used cartridge or a TN starter cartridge is
installed into a machine, it will NOT trigger the machine to reset the toner
you are using genuine Brother toner.
Brother strongly 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.
3. Verify the drum unit and
toner cartridge are installed correctly by performing the following
a. Open the front cover and
remove the drum and toner assembly.
NOTE: We recommend that you place the drum and toner
assembly on a piece of paper in case you accidentally spill or scatter
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.
NOTE: Handle the toner cartridge carefully. If toner
scatters on hands or clothing, immediately wipe it off or wash it with cold
c. Reinstall the toner into
the drum. Be sure it clicks into place. If you put it in properly, the
green lock lever will lift automatically.
d. Reinstall the toner and
drum assembly into the machine and close the front cover.
4. If the problem continues
and you installed a new, unused genuine Brother toner cartridge (TN420 or TN450)
from a sealed foil bag that had never been installed in this or any other
machine, perform the following steps to resolve the issue:
a. Ensure that the most
recent version of the firmware is installed on the Brother machine by
downloading and running the Brother Firmware Update Tool. Refer to the solution
