FAX-2845 Toner | Compatible & Genuine Brother TN420 / TN450

FAX-2845

This listing covers the bundle version of the Brother FAX-2845, the same 21 ppm laser fax as the standard 2845 packaged with OEM toner. Like its sibling it sends Super G3 33.6k faxes with 400 pages of fax memory, feeds originals through a 20-sheet ADF, and prints or copies at 21 ppm over USB. Duplex is manual via the driver, and ongoing replacements are the Brother TN420 or high-yield TN450 with the DR420 drum.

Frequently Asked Questions

Which toner does the Brother FAX-2845 use?

The FAX-2845 uses the Brother TN420 standard-yield toner (~1,200 pages) or the Brother TN450 high-yield toner (~2,600 pages), plus the Brother DR420 drum unit (~12,000 pages).

What is the difference between the TN420 and the TN450?

Both fit the same machines. The TN450 is the high-yield version — it prints about 2,600 pages versus about 1,200 for the TN420 — so it costs less per page if you fax and print a lot.

Are the cartridges on this page original or compatible?

Both — this page carries compatible TN420/TN450 and DR420 replacements as well as genuine Brother OEM TN420 and TN450 toner and DR420 drum.

How often does the DR420 drum need replacing?

The DR420 drum unit is rated for approximately 12,000 pages — roughly four to ten toner changes, depending on whether you use TN420 or TN450 cartridges.
