CAUTION:
Keep the drum unit level after removing the toner cartridge to avoid possible toner spill or
scatter.
Handle the drum unit and toner cartridge carefully. If toner scatters on your hands or
clothes, wipe or wash it off with cold water immediately.
Only unpack a toner cartridge immediately before you need to install it into the printer. If a
toner cartridge is left unpacked for a long period of time, the toner life is shortened
If an unpacked drum unit is subjected to excessive direct sunlight or room light, the unit
may be damaged.
Use a Brother genuine toner cartridge which is specially formulated to ensure top print
quality.
Printing with a 3rd party toner or toner cartridge may reduce not only the printing quality but
also the quality and life of the printer itself. It may also cause serious damage to the
performance and life of a genuine Brother drum unit. Warranty cover is not applied to
problems caused by the use of 3rd party toner or toner cartridges.
Make sure that the wire cleaner on the drum unit is returned to the home position (
