This Brother DR-321CL Drum Unit is quoted as doing up to 25000 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 Brother DR-321CL drum unit. The drum is a rotating roller inside the printer which prints the toner powder from the cartridge onto the transfer belt in your chosen design which is then printed on to the page.
The drum roller will need to be replaced when it starts to wear out to keep all your prints at that high quality standard. The printer will give you plenty of warning so you can get a new drum ready to replace it with. The DR-321CL drum has a yield of up to 25,000 pages, so you shouldn't need to replace it too often.
The Brother DR-321CL drum is packaged in its own box so it can be stored for up to 6 months without its performance being affected which is great if you want to order your new drum in advance.
