Toner Cartridge Maintenance
Life Expectancy
The life of the toner cartridge depends on the amount of toner that print
jobs require. When you print text, a toner cartridge lasts an average of
4,400 pages, printed at 5% coverage. (A typical business letter is about
5% coverage.) This assumes that the print density is set to 3 (default
setting) and the EconoMode feature is turned off\highest quality (default
setting).
Storing Toner Cartridges
Do not remove the toner cartridge from its packaging until you are ready
to use it. The shelf life of a cartridge in an unopened package is
approximately 2 1/2 years. The shelf life of a cartridge in an opened
package is 6 months.
C a u t i o n To prevent damage, do not expose the toner cartridge to light for more
than a few minutes.
Recycling Toner Cartridges
Follow the instructions in the Recycling Instruction Guide included in
the HP toner cartridge box.
Using Non-HP Toner Cartridges
Hewlett-Packard Company cannot recommend use of non-HP toner
cartridges, either new or remanufactured. Because they are not HP
products, HP cannot influence or control their quality.
