Page Yield Up To 30000 Pages

This Brother 4-Colour DR-421CL Drum Unit is quoted as doing up to 30000 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.

Product Description

This is a genuine Brother 4-Colour DR-421CL Drum Unit.

This unit replaces the entire drum in your printer, which houses all four colour toners in your printer. It is a genuine manufacturer part, designed and built by Brother specifically for your printer.

The DR-421CL drum unit is crucial to your printing performance and should be replaced as soon as your printer alerts you. The drum transfer the power from your toner cartridge to the transfer belt, and once it is worn the powder won't be transferred properly, affecting your print quality.

The drum unit is rarely replaced, with a duty cycle of up to 30,000 A4 pages. Order today to enjoy free, fast delivery.
