Brother DR920 Drum Unit for High-Volume Monochrome Laser Printers

Overview

The Brother DR920 is a genuine drum unit engineered for workgroup and departmental laser printers running continuous, high-volume monochrome output. The DR920 delivers an approximate yield of 45,000 pages at 1 page per job — or up to 75,000 pages when jobs average 3 pages on letter/A4 simplex — meaning fewer change-out cycles and less downtime on busy print floors. Consistent toner distribution across the drum surface reduces banding and uneven density that plague off-brand drum substitutes, keeping output quality predictable throughout the drum's life.

Compatibility

The DR920 is designed exclusively for these Brother printer models:

• Single-function laser: HL-L5210DN, HL-L5210DW, HL-L5210DWT, HL-L6210DW, HL-L6210DWT, HL-L6217DW, HL-L6310DW
• Multi-function (DCP/MFC): DCP-L5510DN, MFC-L5710DN, MFC-L5710DW, MFC-L5717DW, MFC-L5915DW, MFC-L6810DW

Pair the DR920 with Brother genuine toner cartridges — TN920, TN920XL, TN920XXL, or the TN920XXL/DR920 bundle — to maintain calibrated toner flow. Using third-party toner cartridges with this drum unit may produce inconsistent density and can shorten drum service life.

Installation Notes

Drum yield will vary based on media type, media size, and job composition. The 75,000-page extended yield applies specifically to 3-page-per-job simplex runs on letter or A4 stock — real-world mixed-duplex environments will fall between the two rated figures. Plan replacement intervals accordingly if your fleet runs heavy duplexing or oversized media.
