CAUTION

Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold 
water at once.

To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.

Note

• Be sure to seal up the drum unit tightly in a suitable bag so that toner powder does not spill out of the unit.
• Go to http://www.brother-usa.com/environment/ for instructions on how to return the used toner cartridge 

to the brother collection program. If you choose not to return your used toner cartridge, please discard the 
used toner cartridge according to local regulations, keeping it separate from domestic waste. If you have 
questions, call your local waste disposal office.

CAUTION

Wait to unpack a drum unit until immediately before you put it in the printer. Exposure to direct sunlight or 
room light may damage the drum unit.

Put the toner cartridge firmly into the new drum unit until you hear it lock into place. If you put the cartridge 
in properly, the green lock lever will lift automatically.
