Compatible Black Drum Unit 4-Pack

This four-pack of Laser Tek Services DR350 compatible black drum units is built for owners of Brother HL-2030, HL-2040, HL-2070N, IntelliFax 2820, 2910, 2920, MFC-7220, MFC-7225N, MFC-7420, MFC-7820N, DCP-7010, DCP-7020 and DCP-7025 printers. Each unit replaces OEM# DR350 and is rated for 12000 pages. Buyers who need colour drums or units for non-listed Brother models cannot use this pack.

Drop-in replacement for OEM DR350

Installation follows the standard Brother drum procedure: open the front cover, remove the toner-and-drum assembly, push the green lock lever and slide the old drum out, then insert the new unit until it clicks. The most common issue is forgetting to reset the drum counter on the printer control panel, which leaves the 'Replace Drum' warning active despite a fresh unit.

12000-page rated yield per drum

The single specification that decides fit is the 12000-page yield at 5% coverage, matching the OEM DR350 rating. If your printing volume regularly exceeds this figure per drum, you will replace units more often than the rating suggests; if you print far less, the drums may age out before the page count is reached.

Questions about this item

How do I know the DR350 drum unit is working correctly after installation?

The drum should produce consistently crisp black prints from the first page through the rated 12000 pages without quality degradation.

What is included in the box and what must I buy separately?

The pack contains four black DR350 drum units; Brother TN350 toner cartridges are sold separately.

Which pack size should I choose for a Brother HL2040 used in a small office?

The four-pack yielding 12000 pages per drum suits higher-volume use and reduces reorder frequency.
