The short answer

DR730 is Brother’s US drum unit for the exact models listed on its product page. It holds the separate toner cartridge. Replacing toner leaves the drum in place.

TONER CARTRIDGEContains toner powderDRUM CARRIERToner locks into this separate assembly
Conceptual diagram: the toner cartridge locks into a separate drum carrier. Replace only the identified component. Illustration, not a test photograph; not to scale. Consult the model manual for actual handles, surfaces and paper paths.

The number on the box

Look for DR730 and “drum unit.” TN730 and TN760 are toner cartridges, even though the numbers look similar. They are not substitute products.

What the stated life means

Brother describes approximately 12,000 pages under its stated use conditions. Actual life varies with the way you print, including pages per job. This is not a guarantee that your drum has failed at a particular page count.

Already put in a new one?

Check that the toner is locked into the drum carrier and the assembly is fully seated, following the exact-model checklist. Then use the correct drum-counter reset for the control panel. The button and touchscreen sequences differ.

Confirm the full model and market

Use the linked DR730 compatibility guide for the six checked US models. The UK HL-L2350DW reference specifies DR-2400; a matching model name does not make a US supply universal.
