The Brother MFC-L2750DW's DR-730 drum unit outlasts its toner by 4x

The MFC-L2750DW uses the TN-760 (roughly 3,000 pages) or the starter TN-730 (just 1,200 pages), and what’s worth noting is the separate DR-730 drum unit good for about 12,000 pages. That means you’ll go through three or four toner swaps before the drum needs attention, which is a nice rhythm — the drum cost is amortized across several toner cycles rather than hitting you every time.
