What toner and drum unit does the Brother HL-L2350DW use?

The Brother HL-L2350DW uses standard TN-730 toner cartridges — standard yield gets about 1,200 pages, high-yield TN-730XL gets about 3,000 pages — and a separate DR-730 drum unit that lasts about 15,000 pages. That separation keeps running costs lower than all-in-one cartridge designs.
