period of time, the toner life is shortened.

Brother strongly recommends that you do not refill the toner
cartridge provided with your MFC. We also strongly recommend
that you continue to use only Genuine Brother Brand
replacement toner cartridges (TN-540 or TN-570). Using or
attempting to use potentially incompatible toner and/or toner
cartridges in your MFC may cause damage to the machine itself
and/or it may result in unsatisfactory print quality. Our warranty
coverage does not apply to any problem that was caused by the
use of unauthorized third party toner and toner cartridges. To
protect your investment and guarantee your print quality please
continue to replace consumed toner cartridges with only Genuine
