You CANNOT install a
partially used toner cartridge from another printer. Only a brand new TN670
toner cartridge from a sealed Brother carton can be used to reset "Toner Life
If "Toner Life End" is still
on the LCD (display) after installing a new TN670 toner cartridge:
1. Verify 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 work 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 toner cartridge
is installed correctly.
a. Press the cover release
button on the top of the printer and open the front cover.
b. Remove the drum unit and
toner cartridge assembly.
NOTE: We recommend you place the toner and drum assembly on a
piece of paper in case you accidentally spill or scatter toner.
c. Remove the toner cartridge
from the drum by holding down the blue lock lever on the right side of the
drum 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
d. Gently rock the toner
cartridge from side to side five or six times to distribute the toner evenly
inside the cartridge.
e. Place the toner cartridge
into the drum (be sure it clicks into place).
f. Clean the primary corona
wire inside the drum by gently sliding the blue tab on the top of the cartridge
from left to right several times. Return the blue tab to the home position
before reinstalling the drum assembly.
g. Reseat the
drum into the printer pressing it in securely.
h. Close the front cover
making sure it latches on both sides.
3. If the LCD message
is cleared, no further troubleshooting is needed.
