The DR‑820 compatible imaging drum is a high‑yield replacement drum unit built for certain monochrome laser printers from Brother.
This drum unit supports a page yield of up to ≈ 30,000 pages (at 5% page coverage).
When installed correctly (and used with compatible toner such as TN-820 Toner Cartridge / TN-850 Toner Cartridge), the DR‑820 ensures consistent print density, sharp text, and clean monochrome output — ideal for office reports, business documents, invoices, manuals, and heavy printing tasks.
As a high-yield drum, it’s especially suited for home offices, small-to-medium businesses, and high-volume printing environments where cost‑effectiveness and long-lasting performance matter.
