Caution
■Wait to unpack the toner cartridge until immediately before you install it in the MFC. If a toner cartridge is left unpacked for a long 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
