Product Description
The
Brother DR-B021 Drum Unit Cartridge is a genuine mono laser imaging drum engineered to transfer toner onto paper with crisp, professional accuracy. It acts as the central mechanism for image formation and functions completely separate from the toner cartridge.
Key Technical Specifications
- Page Yield: Generates approximately 12,000 pages based on standard ISO/IEC 19752 testing.
- Print Output: Exclusively designed for monochrome (black and white) laser printing.
- Weight: Standard physical unit weighs around 350 grams.
- Function: Houses the laser toner cartridge and acts as the developer surface to map characters onto paper.
Main Printer Compatibility
The drum unit works seamlessly across Brother's TonerBenefit printer lineup, which includes both single-function and multi-function monochrome laser devices:
- HL Series (Single-Function): HL-B2000D, HL-B2050DN, HL-B2080DW, HL-B2100DB, HL-B2180DWB.
- DCP Series (Multi-Function): DCP-B7500D, DCP-B7520DW, DCP-B7530DN, DCP-B7535DW, DCP-B7620DWB, DCP-B7640DWB.
- MFC Series (Multi-Function / Fax): MFC-B7700D, MFC-B7715DW, MFC-B7720DN, MFC-B7810DWB.
Performance and Reliability
- Crisp Typography: Designed to deliver sharp text definitions and clean, smooth grayscale graphics for business documents.
- Jam-Free Mechanics: Engineered precisely to match printer feed rates, avoiding common third-party alignment errors and paper jams.
- Separate Design: Because it is detached from the actual toner container (TN-B021), you only replace the drum after exhausting its full 12,000-page lifespan. This reduces cumulative operational costs compared to unified all-in-one cartridge setups.
