HL-2135W Toner | Compatible & Genuine Brother TN420 / TN450

HL-2135W

Cutting the USB cord is the Brother HL-2135W's claim to fame, adding Wi-Fi 802.11b/g to the same 20 ppm mono engine as the HL-2130 and HL-2132. It also doubles memory to 16MB, while duplex stays manual through the driver and there is no Ethernet port. Wireless home offices can feed it Brother TN420 toner (about 1,200 pages) or the high-yield TN450 (about 2,600 pages) with the DR420 drum.

Frequently Asked Questions

Which toner does the Brother HL-2135W use?

The HL-2135W 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?

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.
