Brother MFC-9970CDW toner
Your MFC-9970CDW takes the TN315BK (high yield), TN315C (high yield), TN315M (high yield) and TN315Y (high yield). At our price that is about 0.4¢ a page.
The Brother MFC-9970CDW is a mono laser printer.
It takes 4 cartridges: the TN315BK, TN315C, TN315M and TN315Y.
Brother has stated publicly that its firmware updates do not block third-party cartridges, and the printer counts pages rather than measuring toner, which is why the Replace Toner message can appear before a cartridge is empty.
When you compare prices, compare cost per page rather than the sticker price: a cheaper cartridge with half the rated yield costs more to run. Every cartridge here ships free, is covered by our printer damage protection and can be returned within 90 days, opened or not.
