A:Answer The Brother HLL2370DW machine comes with (1) Starter Toner Cartridge (yields approx. 700 pages). The replacement cartridges are TN730 Standard-yield Toner, Black, Yields approx. 1,200 pages, TN760 High-yield Toner, Black, Yields approx. 3,000 pages and TN770 Super High-yield Toner, Black, Yields approx. 4,500 pages.
Stated page yields for genuine Brother cartridges are based on the ISO testing standards. The number of pages that can be printed with a cartridge is affected by several factors, including paper size, number of pages per print job, amount of print on each page, font size, and print content (graphics, charts, etc.). Print jobs with large text fonts, graphics, charts, and/or large amount of solid coverage (black or any given color) will use much more toner and will shorten the life of the toner cartridge.
