What is the difference between the MFC-L2753DW and the L2750DW toner and drum?

The MFC-L2753DW uses the same TN-760/TN-730 toner as the L2750DW, but its DR-730 drum lasts 15,000 pages instead of 12,000. That extra 3,000 pages means you’ll swap toner four or five times before replacing the drum, making per-page equipment cost slightly lower over the machine’s life.
