MAINTENANCE
1
Open the front cover and pull out the drum unit.
Place the drum unit on a drop cloth or large piece of disposable paper to avoid spilling and
scattering the toner.
2
Hold down the lock lever on the right and pull the toner cartridge out of the drum unit assembly.
3
Remove the old toner cartridge from the drum unit by gently pulling it out.
4
Unpack the new toner cartridge. Place the used toner cartridge into the aluminium bag and
discard it according to local regulations.
Handle the toner cartridge carefully. If toner scatters on your hands or
clothes, immediately wipe it off or wash them with cold water.
• Wait to unpack the toner cartridge until immediately before you install it
into the machine. If a toner cartridge is left unpacked for a long period of
time, the toner life is shortened.
• You can use only a genuine Brother toner cartridge (TN-6300 or TN-6600),
which is specially formulated to ensure top print quality. Using another
brand of toner cartridge may void your machine’s warranty.
