Brother TN-243BK toner cartridge, black, 1000 pages

Black toner goes onto almost every page, from invoices and letters to tables and notes. The manufacturer gives the cartridge a yield of 1000 pages. That is a calculated figure: dense tables, bold headings and large dark areas use toner faster, sparse text more slowly. If you print a lot, keeping a spare cartridge at hand means a swap never lands in the middle of a job.

Owners of a Brother printer at home or in a small office that takes TN-243 series toners and is running low on black. The manufacturer data has no list of compatible printers, so compare the TN-243BK code with the cartridge in the printer or with the manual before swapping. The pack holds only the black cartridge; other colours are replaced separately.
