CAUTION Note Print-cartridge storage Do not remove the print cartridge from its package until you are ready to use it. Print cartridges should be stored in an environment ranging from minus-20 degrees Celsius to 40 degrees Celsius (minus-4 degrees Fahrenheit to 104 degrees Fahrenheit). Store the supply in a horizontal position in a dark, dry location away from heat and magnetic sources. To prevent damage to the print cartridge, do not expose it to light for more than a few minutes. 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 percent coverage (typical for a business letter), an HP print cartridge lasts an average of 6,000 pages. This assumes that toner density is set to 3 and EconoMode is off. (These are the default settings. For details about these settings, see the description of ECONOMODE and TONER DENSITY in "Print-quality submenu" on page 61.) At any time, you can verify life expectancy by checking the supply level, as described in "Checking the supply level" on page 79. Hewlett-Packard recommends that a print cartridge be completely used within six months of opening the cartridge's packaging. 78 Printer maintenance ENWW
