HP 4250/4350 manual Print-cartridge life expectancy, Checking the supply level

Print-cartridge life expectancy

The life of the print cartridge depends on the amount of toner that print jobs require and the length of life for the components inside the cartridge. When printing text at 5% coverage (typical for a business letter), the HP print cartridge lasts an average of 10,000 (Q5942A) or 20,000 (Q5942X) pages.

At any time, you can verify life expectancy by checking the supply level, as described in Checking the supply level.
