Page Yield Up To 2500 Pages

This Brother TN321 Black Toner Cartridge is quoted as doing up to 2500 pages before needing to be replaced.

The page yield is calculated by manufacturers using ISO/IEC 24711 standards, where they print set documents of 5% page coverage until the cartridge is empty. The standard means you can compare yields between cartridges and manufacturers.
