The XL marking stands for a high-yield cartridge: the manufacturer rates it at around 500 pages. That is a calculated reference figure – documents with a lot of black, such as graphics, charts or photos, use ink faster, while sparse pages use it more slowly. Each colour sits in its own cartridge, so the black one is replaced independently of the others.
Owners of a Brother DCP-J1140DW, DCP-J1800DW, MFC-J1010DW or MFC-J1012DW whose printer has run out of black ink. Only the empty cartridge needs replacing rather than the whole set, because the colours are separate. Check the model name on the printer before swapping and compare it with the manufacturer's compatibility list.
