The life of the print cartridge depends on usage patterns and the amount of toner that print jobs require. For example, when printing text at 5 percent coverage, an HP print cartridge lasts an average of 4,000 or 6,000 pages, depending on the printer model. (A typical business letter is about 5 percent coverage.)
Cartridge life expectancy is reduced by frequently printing many 1- or 2-page jobs, heavy coverage, and automatic duplexing. At any time, you can verify the life expectancy by checking the print cartridge life. See Checking the print-cartridge life for more information.
