CAUTION EN Toner cartridge storage Do not remove the toner cartridge from its package until you are ready to use it. The shelf life of a cartridge in an unopened package is approximately 2.5 years. To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes. Toner cartridge life expectancy The life of the toner cartridge depends on the amount of toner that print jobs require. When printing text at 5% coverage, an HP toner cartridge lasts an average of 10,000 or 6,000 pages, depending on which toner cartridge is installed. (A typical business letter is about 5% coverage.) This assumes that print density is set to 3 and EconoMode is off. (These are the default settings. For details on other settings, see the description of ECONOMODE and TONER DENSITY in "Print Quality Menu" on page 217.) At any time, you can verify life expectancy by checking the toner level, as described below.
