HP and 8150 MFP manual Toner Cartridge Life Expectancy, Checking the Toner Level

Chapter 4 Printer Maintenance 192

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 20,000 pages. (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.)

Checking the Toner Level

The user can find out how much toner is left in the printer cartridge by printing a configuration page (see page 314). The Toner Level section on the configuration page provides a graphical representation of how much toner is left in the cartridge.

Note	This value might become inaccurate if a user fails to select YES when the
	NEW TONER CARTRIDGE=NO message is displayed on the control panel after
	replacing a low toner cartridge.
