Working with the Toner Cartridge
Toner Cartridge Life
The life of your toner cartridge depends on the amount of toner your print
jobs require. When you print word-processed text, average toner cartridge
yield is 7,500 pages, printed at 5% coverage (a typical full-page business
letter is about 5% coverage). This assumes that the print density setting is
in the middle range (see “Adjusting Print Density” in Chapter 5, “Special
Tasks”).
Using EconoMode can further extend average toner cartridge yield (see
“Saving Toner with EconoMode” in Chapter 5, “Special Tasks”).
Note
HP does not recommend full-time use of EconoMode. Full-time use will
result in a loss of print quality due to normal toner cartridge mechanical
wear.
Storing, Installing, and Recycling the Toner
Cartridge
Storing: Do not remove the toner cartridge from its packaging until you are
ready to use it. The shelf life of an unopened cartridge package is
approximately 2 1/2 years of storage; the shelf life of an opened cartridge
package is approximately six months. Use the cartridge before the
expiration date (the expiration date is stamped on your toner cartridge box).
Installing and Recycling: To install a new toner cartridge, follow the
instructions in the Installation Guide included in your toner cartridge box.
A separate Recycling Instruction Guide is also included.
HP’s Policy on Use of Non-HP Toner Cartridges
Hewlett-Packard 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.
