Unpack the new toner cartridge. Place the used toner cartridge into
the aluminum bag and discard it accoring to local regulations.

■ 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-200 series),

which is specially formulated to ensure top print quality. Using
another brand of toner cartridge may void your machine’s warranty.

Gently rock the toner cartridge from side to side five or six times.
