Print cartridge life expectancy
The life of the print cartridge depends on usage patterns and the amount of toner that print jobs require.
HP print cartridges last an average of 12,000 pages when printing on letter or A4-size paper at 5%
coverage for each print cartridge. Usage conditions and print patterns may cause actual results to vary.
At any time, you can verify the life expectancy by checking the toner level, as described below.
