Important
• Wait to unpack the new toner cartridge until immediately before you put it in the machine. If a toner
cartridge is left unpacked for a long time, the toner life will be shortened.
• If an unpacked drum unit is put in direct sunlight or room light, the unit may be damaged.
• Brother strongly recommends that you DO NOT refill the toner cartridge provided with your machine. We
also strongly recommend that you continue to use only Genuine Brother Brand replacement toner
cartridges. Use or attempted use of third party toner and/or cartridges in the Brother machine may cause
damage to the machine and/or may result in unsatisfactory print quality. In addition, use of third party toner
and/or cartridges may trigger incorrect status messages, cause the printer to stop prematurely or
otherwise malfunction. Our limited warranty coverage does not apply to any problem that is caused by the
use of third party toner and/or cartridges. To protect your investment and obtain premium performance
from the Brother machine, we strongly recommend the use of Genuine Brother Supplies.

Important
Put the toner cartridge in the drum unit immediately after you have removed the protective cover. To
