Brother LC-223BK ink cartridge, black, 600 pages

The black cartridge prints text, tables and invoices, so in an office it is often the one used up fastest. The manufacturer rates it at around 600 pages to ISO/IEC 24711, an international method for measuring inkjet cartridge yield that makes figures for different cartridges comparable. Dense text and dark images use more ink.

Owners of a Brother DCP or MFC series inkjet printer whose model is on the manufacturer compatibility list, which names eight models in total. The colours sit in separate cartridges, so the black one can be replaced on its own when text starts to fade or the printer warns that black ink is running low.
