Ninestar Technology DR730 toner cartridge

Compatible Drum Unit for Brother Printers

The Ninestar Technology DR730 is a new aftermarket drum unit built to replace the Brother DR730 in models such as the DCP-L2550DW, MFC-L2710DW, MFC-L2717DW, MFC-L2730DW, HL-L2350DW, HL-L2370DW and HL-L2370DWXL. It ships as a single black cartridge with a two-year shelf life and is manufactured to meet or exceed OEM requirements without affecting the printer warranty. Buyers needing colour drums or toner cartridges rather than a drum unit should look elsewhere.

Standard Yield Capacity and Page Coverage

Rated as a standard yield unit, the DR730 handles everyday monochrome printing in home offices and small workgroups. It provides reliable output for typical document volumes but will reach end of life sooner under heavy graphics or continuous high-coverage jobs. Environments that demand high-capacity drums or separate toner bottles are not served by this cartridge.

Operating Conditions and Power Profile

The drum operates between 10 °C and 30 °C with humidity from 20 % to 80 %, and can be stored from -20 °C to 40 °C at the same humidity range. Within these limits it runs quietly with no additional power draw beyond the printer’s normal consumption. Installations in uncontrolled warehouses or non-climate-controlled spaces outside the stated temperature window may see reduced print quality or shortened drum life.
