Genuine Drum Standard Yield, 16,000 pages
The MFC 4000ML uses a single toner cartridge, BRT TN100PPF (BRT TN-100PPF). BRT TN100PPF yields 3000 pages.
The CTC TN100PPF cartridge has an approximate yield of 3000 pages.
For BRT TN100PPF you can choose Genuine Brother (BRT TN100PPF (BRT TN-100PPF)) or a Remanufactured option (CTC TN100PPF) at a lower price per page, same 3000 page yield.
Yes — the MFC 4000ML uses a replaceable imaging drum: BRT DR100 (BRT DR-100).
A "Toner" notice on the MFC 4000ML usually relates to its drum unit or toner cartridge, not a hardware fault. Open the front cover, pull out the assembly, and reinsert it firmly to clear contact errors. If the printer reports the drum is spent, swap in BRT DR100 and reset the counter; for toner, use CTC TN100PPF.
