Frequently Asked Questions


How are “High-Yield” and “Ultra High-Yield” capacity cartridges different?


Both “High-Yield” and “Ultra High-Yield” cartridges contain more ink than the standard cartridges of the same size. This means that the Brother TN850 / TN820 Black High-Yield Compatible Toner Cartridge can print up to 8,000 pages, the Brother TN880 Black Super High-Yield Compatible Toner Cartridge can print up to 12,000 pages, and the Brother TN890 Black Ultra High-Yield Compatible Toner Cartridge can print up to 20,000 pages. Note that these numbers may change depending on how often you print and your printer's settings.


How are the drum unit and toner cartridge different?


Your printer uses both the drum unit and toner cartridge to print your documents. While the toner cartridge stores the ink used for printing, the drum unit transfers this ink from the toner cartridge onto the paper you're using for printing.
