This Canon C-EXV21 Black Drum Unit is quoted as doing up to 77000 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.
