MFC-7225N

Like the rest of its family, the Brother MFC-7225N prints from the TN350 toner cartridge working inside the DR350 drum unit, a separate component rated for up to 12,000 pages. The genuine Brother TN350 cartridge is rated at 2,500 pages, and the compatible line on this page runs from a single cartridge to a 4 pack, with the genuine Brother toner and drum listed alongside.

The 7225N is the network-minded variant in a family whose members all drink from the same supply shelf — it shares its cartridge and drum with the MFC-7220 and the two dozen other models listed below. For anyone looking after several of these machines, that commonality is the real feature: one toner number to stock, one drum number to track, and no per-machine surprises when a cartridge runs out.

Which cartridge should you buy?

Because the cartridge is shared so widely, pack buying is where the savings sit for this model. A single TN350 covers a quiet month; the 2 pack and 4 pack keep a small fleet printing without repeat orders, and the per-cartridge cost falls as the pack grows. Choose the genuine Brother TN350, rated at 2,500 pages, if you want the factory fill; check each compatible listing's product page for its stated yield. Keep the DR350 drum, rated up to 12,000 pages, on a separate mental list — it is ordered rarely, and usually alongside a pack rather than alone.

Chip, toner and everyday use

Swapping the cartridge on the MFC-7225N means handling the combined toner-and-drum assembly, and the drum half deserves a little care: support it from underneath, keep its surface away from bright light while it is out, and never touch the imaging area with bare fingers. The new cartridge seats with a click, and the machine counts pages from there. Store spare packs flat and sealed; toner keeps well, but a cartridge that has sat open in a damp room rarely prints its best.

Frequently Asked Questions

Does the MFC-7225N take the same cartridge as the MFC-7220?

Yes. Both machines use the TN350 toner cartridge in the DR350 drum unit, and the same is true across the family list below, which is why one shelf of cartridges can serve several different models.

What pack sizes are sold for this model?

The TN350 is listed as a single cartridge and in 2, 3 and 4 packs, plus a set that pairs the toner with a DR350 drum. The genuine Brother TN350 cartridge is also listed on its own.

When should the DR350 drum be replaced?

The drum is rated for up to 12,000 pages, far beyond a single cartridge. Replace it when output quality fades or marks repeat down the page even with a fresh TN350 fitted.

Are compatible TN350 cartridges covered by a warranty?

Yes. Compatible cartridges from Clever Supplies carry a 1-year warranty and 1-year returns, so a cartridge that misbehaves can be sent back rather than written off.
