The service life of the toner cartridge depends on the amount of toner required for print jobs. A
new toner cartridge can print an average of 3,000 pages, with 5% coverage, on A4 paper. The
actual number of pages may vary according to print density, and is affected by the operating
environment and print interval, as well as the type and size of media to be printed. The toner
cartridge may need to be changed frequently if printing numerous graphs.
