Managing supplies Using, storing, and monitoring print cartridges can help ensure quality printer output. Supplies life 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.
