Caution
• Wait to unpack the Toner cartridge until immediately before you install it
in the printer. If Toner cartridges are left unpacked for a long period of
time the toner life will be shortened.
• If an unpacked Drum unit is subjected to excessive direct sunlight or
room light, the unit may be damaged.
• Use a genuine Brother Toner cartridge that is specially formulated to
ensure optimum print quality.
• Printing with a 3rd party toner or 3rd party Toner cartridge may reduce
not only the print quality but also the quality and life of the printer itself. It
may also cause serious damage to the performance and life of a Drum
unit. Warranty coverage does not apply to problems caused by the use
of 3rd party toner, 3rd party Toner cartridges or 3rd party Drum units.
