IntelliFax-2840 Toner | Compatible & Genuine Brother TN420 / TN450

Intellifax 2840

Some offices still run on fax, and the Brother IntelliFAX-2840 is built unapologetically for them. A 33.6Kbps Super G3 modem drives the 21 ppm print and copy engine, with a 20-page ADF and 250-sheet tray handling the day's traffic — no Ethernet, no wireless, just USB for PC printing. It runs the economical TN420 or high-yield TN450 cartridges alongside the DR420 drum, rated around 12,000 pages.

Frequently Asked Questions

Which toner does the Brother IntelliFax-2840 use?

The IntelliFax-2840 uses the Brother TN420 standard-yield black toner (~1,200 pages) or the Brother TN450 high-yield black toner (~2,600 pages), paired with the Brother DR420 drum unit (~12,000 pages).

What is the difference between the TN420 and TN450?

Both fit the same machine — the TN450 is the high-yield version. It prints about 2,600 pages per cartridge versus about 1,200 for the TN420, so it costs less per page for heavier fax and copy volumes.
