How often should one replace the toner in a Brother TN570 printer?

Answer 1

The toner cartridge in a C3903A printer is capable of printing up to 4,000 pages. How often you have to change your toner cartridge depends on how often you use your printer and what kinds of documents you are printing.

Answer 2

The Brother TN570 is not a printer but a toner cartridge. You should replace it about every 5,000 pages. If you get the high yield toner cartridge it will last longer and be more cost effective.
