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 approximately 5%
coverage (typical for a business letter), the HP print cartridge lasts an average of 18,000
pages. The page-yield specification that HP provides is a general guideline. Actual yield can
vary according to usage conditions.

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