This Brother TN-421BK Black Toner Cartridge is quoted as doing up to 3000 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.
This is a genuine standard capacity Brother TN-421BK Black Toner Cartridge.
This toner is manufactured by Brother specifically for your printer, and is designed for normal volume users that want to keep their print ticking over smoothly. The standard capacity black gives a yield of up to 3,000 pages, perfect for small-to-medium office use.
This TN-421BK is the same size as the higher capacity toner and will install into your printer as usual, the only difference is how much toner it contains. That means you get the same reliability and high print quality you're used to.
