Managing the Toner Cartridge
HP Policy on 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 their design or control their quality.
To install a new HP toner cartridge and recycle the used cartridge, 
follow the instructions included in the toner cartridge box.
Toner Cartridge Storage
Do not remove the toner cartridge from its package until you are 
ready to use it. (The shelf life of a cartridge in an unopened package 
is approximately 2.5 years.)
Caution
To prevent damage to the toner cartridge, do not expose it to light 
for more than a few minutes.
Toner Cartridge Life Expectancy
The life of the toner cartridge depends on the amount of toner that 
print jobs require. When printing text at 5% coverage, an HP toner 
cartridge lasts an average of 10,000 pages. (A typical business 
letter is about 5% coverage.) This assumes that print density is set 
to 3 and EconoMode is off. (These are the default settings.)
