The cartridges work with a long list of Brother DCP, HL, MFC and IntelliFax models including the 2240D, 2270DW, 7055, 7057, 7060D, 7065DN, 7070DW, 2130, 2132, 2220, 2230, 2240, 2242, 2250, 2270, 2280, 2840, 2940, 7240, 7360, 7460, 7470 and 7860 series. Verify that your exact model appears in this list because cartridges will not fit or function in other Brother printers.

The units are designed to operate between ten and 32.5 degrees Celsius at twenty to eighty percent relative humidity and can be stored from minus twenty to forty degrees Celsius at the same humidity range. These conditions help maintain print quality and shelf life.

Questions about this item

What comes inside the 3-pack box and do I need to buy a drum unit separately?

The box contains three black toner cartridges; a drum unit is not included and must be purchased separately if your printer requires one.

How do I decide between the TN420 and TN450 versions listed for this cartridge?

This single cartridge replaces both Brother TN420 and TN450, so there is no separate version to choose — one SKU covers both.

What does the 2600-page yield mean when I print typical office documents?

Each cartridge prints roughly 2600 pages at 5 % coverage; heavier text or graphics will reduce the actual page count.
