HP policy on non-hp print cartridges
Hewlett-Packard Company cannot recommend the use of non-HP print cartridges, either new,
refilled, or remanufactured. Because they are not HP products, HP cannot influence their
design or control their quality. Service or repair required as a result of using a non-HP print
cartridge will not be covered under the printer warranty.
Note The warranty does not apply to defects resulting from software, interfacing, or parts not
supplied by HP.
To install a print cartridge
To install a print cartridge, see the start guide.
Storing print cartridges
Do not remove the print cartridge from its package until you are ready to use it. Some
HP LaserJet print cartridge packages are stamped with an alphanumeric date code. This code
represents a 30-month period beyond the date of production in order to facilitate efficient
inventory management processes between HP and its resellers. It does not serve as an
indication of toner life (shelf-life) or relate in any way to warranty terms and conditions.
CAUTION To prevent damage to the print cartridge, do not expose it to light.
Print cartridge life expectancy
The life of the print cartridge depends on the amount of toner that your print jobs require.
When printing text on letter/A4-size paper at 5 percent coverage, the print cartridge lasts an
average of 2,000 pages. This assumes that you set the print density to 3 and turn EconoMode
off (these are the default settings).
