Black is the most used colour in a colour printer: it prints text, tables and black-and-white pages. The manufacturer rates the TN-249BK at around 4500 pages, more than the colour cartridges of the same series. That is a reference figure; densely filled pages and dark images use toner faster.
Offices running one of the four listed Brother printers and printing a lot of text. Black has its own cartridge, so only it is replaced while the colour cartridges stay in the printer. The printer model name is shown on the front panel or housing.
