8-Pack Compatible Drum Unit for Brother DR820

This set contains eight black drum units built as aftermarket replacements for the Brother DR820. It fits a wide range of Brother DCP, HL and MFC laser printers used in office environments. Each unit is manufactured under ISO 9001 and ISO 14001 quality management systems. The product is supplied new and ready for installation.

30000-Page Yield at 5% Coverage

Every drum unit in the pack is rated for approximately 30000 pages when printing at 5% coverage. That capacity supports high-volume departments without frequent changeovers. The yield drops when pages carry heavier toner density or graphics. Users printing large solid areas will reach the end of life sooner than the rated figure.

Operating Range 10 to 32.5°C

The drum units are specified to operate between 10 and 32.5°C with relative humidity from 20% to 80%. Storage tolerances extend from -20°C to 40°C at the same humidity band. Staying inside these limits helps maintain print quality and mechanical reliability. Extreme conditions outside the range can degrade the photosensitive surface.

Questions about this item

Will these DR820 drum units work in my older Brother HL-L5200DW that I plan to keep?

Yes, the compatible-products list includes the HL-L5200DW so each of the eight black drum units will operate in that printer.

How can I verify the drum units are performing correctly once installed?

Print a test page and check that the printer reports normal drum life; each unit is rated for 30000 pages at 5% coverage.

What comes in the box and is anything else required?

The pack contains eight black drum units and installation notes; toner cartridges are sold separately.
