GREENCYCLE DR221 Compatible Drum Unit Black 4 Pack

Compatible Drum Unit for Brother Printers

The GREENCYCLE DR221 drum unit replaces the Brother original in HL-3140CW, HL-3150CW, HL-3170CDW, HL-3180CDW, MFC-9130CW, MFC-9330CDW, MFC-9340CDW and DCP-9020CDN laser printers. It is sold as a four-pack of black units, each manufactured new and ready to install. The product targets offices and home users who need a direct replacement without changing their existing hardware. Buyers using non-listed Brother models or colour-only workflows should verify compatibility before ordering.

15,000-Page Yield per Drum

Each drum unit is rated for up to 15,000 pages at .05 coverage on A4 or Letter paper. That headroom suits regular document printing and moderate graphics work across a small workgroup. Heavy-coverage jobs such as full-page photos or dense marketing materials will reach the limit sooner than the rated figure. The four-pack extends the replacement interval but does not increase the per-unit yield.

User Manual and Multi-Pack Convenience

The box includes a user manual plus the four black drum units, giving immediate spares for staggered replacements. Installation follows the standard Brother sequence: unpack, shake the companion toner cartridge, remove the orange cover, insert the toner into the drum, then seat the assembly in the printer. No software, chips or firmware tools are bundled. Users who prefer automated supply tracking or cloud-based fleet management must rely on the printer’s own features.
