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-8000 series), which is specially formulated to ensure top print quality. Using another brand of toner cartridge may void the machine’s warranty.

5 Gently rock the toner cartridge from side to side five or six times, and then remove the protective seal.
