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.
