Brother HL-L6415DWT toner
Your HL-L6415DWT takes the TN920UXXL (high yield), TN920 (standard yield), TN920XL (high yield) and TN920XXL (high yield). At our price that is about 0.3¢ a page.
The Brother HL-L6415DWT is a mono laser printer in the HL-L6400 series, which shares cartridges across 6 models.
It takes two black cartridges that differ only in capacity: the TN920 at about 3,000 pages and the TN920UXXL at about 18,000. At our prices that is 1.2¢ a page against 0.3¢, so the high-yield cartridge costs less to run unless you print very little.
Brother has stated publicly that its firmware updates do not block third-party cartridges, and the printer counts pages rather than measuring toner, which is why the Replace Toner message can appear before a cartridge is empty.
When you compare prices, compare cost per page rather than the sticker price: a cheaper cartridge with half the rated yield costs more to run. Every cartridge here ships free, is covered by our printer damage protection and can be returned within 90 days, opened or not.
