Using HP toner cartridges
HP policy on non-HP toner cartridges
Hewlett-Packard Company cannot recommend the use of
non-HP toner cartridges, either new, refilled, or remanufactured.
Since they are not HP products, HP cannot influence their design
or control their quality.
Note The warranty does not apply to defects resulting from software,
interfacing, or parts not supplied by HP.
Storing toner cartridges
Do not remove the toner cartridge from its package until you are
ready to use it. The shelf life of a toner cartridge in an unopened
package is approximately 2.5 years. The shelf life of a toner
cartridge in an opened package is approximately 6 months.
CAUTION To prevent damage to the toner cartridge, do not expose it to light.
Toner cartridge life expectancy
The life of the toner cartridge depends on the amount of toner
that your print jobs require. When printing text at 5% coverage,
the standard toner cartridge (C7115A) lasts an average of
2,500 pages. The extended life toner cartridge (C7115X) lasts an
average of 3,500 pages. This assumes that you set the print
density to 3 and turn EconoMode off. (These are the default
settings.)
