Brother MFC-9340CDW toner and drum
Your MFC-9340CDW takes the TN221Y (standard yield), TN221BK (standard yield), TN221C (standard yield), TN221M (standard yield), TN225C (high yield), TN225Y (high yield) and TN225M (high yield), plus the DR221CL drum. At our price that is about 0.8¢ a page.
The Brother MFC-9340CDW is a mono laser printer in the MFC-9300 series, which shares cartridges across 4 models.
It takes two black cartridges that differ only in capacity: the TN221Y at about 1,400 pages and the TN225C at about 2,200. At our prices that is 1.4¢ a page against 1.0¢, so the high-yield cartridge costs less to run unless you print very little.
The drum is a separate part on this printer. The DR221CL is rated for about 15,000 pages, so it outlasts several toner cartridges and only needs replacing when the printer reports drum life, not every time you change toner.
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.

Questions about the MFC-9340CDW
What toner does the Brother MFC-9340CDW use?
The TN221Y, TN221BK, TN221C, TN221M, TN225C, TN225Y and TN225M. Brother lists these cartridges as compatible with this model, and the yields on this page are Brother's published figures.
Does the MFC-9340CDW have a separate drum?
Yes. The DR221CL drum unit is a separate part rated for about 15,000 pages. Replace it when the printer reports drum life, not when you change toner.
Does using a compatible cartridge void the MFC-9340CDW warranty?
No. Under the Magnuson-Moss Warranty Act a manufacturer cannot void your warranty because you used a third-party cartridge. If one of ours damages the printer, our printer damage protection covers the repair.
