DCP-2240D Toner | Compatible Brother TN420 / TN450 & DR420

DCP-2240D

Retailer listings group the Brother DCP-2240D with the TN420/TN450 toner family, and its hardware appears to track the HL-2240D printer at 24 pages per minute. Automatic duplexing and a 250-sheet tray make it a capable print/copy/scan all-in-one for a USB-connected desk, pairing the ~1,200-page TN420 or high-yield TN450 with the DR420 drum. Factory documentation for this DCP variant is thin, so the specs below follow its closest documented sibling.

Frequently Asked Questions

Which toner does the Brother DCP-2240D use?

The DCP-2240D 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 printers. 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 print a lot.

Are the cartridges on this page original or compatible?

The cartridges on this page are compatible replacements for the Brother TN420, TN450 and DR420, built to match the originals' fit and page yield.

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.
