eSquareOne S1-BR-DR820-01 Drum Unit

The eSquareOne S1-BR-DR820-01 is a compatible replacement drum unit for the Brother DR820. It is designed for offices using Brother DCP, HL or MFC laser printers listed in the compatibility data. The unit ships new in a single black cartridge pack. It targets buyers who need a direct OEM alternative for high-volume mono printing.

30000-page yield at 5% coverage

Rated yield reaches 30000 pages when measured at the industry standard 5% page coverage. Actual output drops significantly with graphics, dense text or frequent duplex jobs. The drum operates reliably between 10 and 32.5°C and 20 to 80% relative humidity. Storage outside the -20 to 40°C range risks premature wear.

Straightforward swap with included notes

Installation follows the standard Brother drum replacement procedure and the box includes printed guidance notes. Common issues arise when the printer fails to reset the drum counter, requiring a manual menu reset. The unit is not for colour printers, for models outside the listed series or for users expecting integrated toner supply.

Questions about this item

This drum unit replaces the Brother DR820 — is it the only version available for these printers?

This pack contains one black drum unit that replaces the Brother DR820 and fits the listed DCP, HL and MFC models.

The spec says 30,000 pages at 5% coverage — what does that look like in daily printing?

At 5% coverage the drum is rated for 30,000 pages; actual yield varies with page content, print density and environmental conditions.

Does the drum connect via a standard interface or does it need a proprietary slot?

The drum unit installs directly into the printer's dedicated drum cavity — no separate cable or interface is required.
