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% 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% coverage.)
Cartridge life expectancy is reduced by frequently printing many one- or two-page jobs,
heavy coverage, and automatic duplexing. At any time, you can verify the life expectancy by
checking the print cartridge life. For more information on how to check the life of the print
cartridge, see the user guide.
