Environmental Product Stewardship
Protecting the Environment
Hewlett-Packard Company is committed to providing quality
products in an environmentally-sound manner. The printer has been
designed to minimize impacts on the environment.
The printer design eliminates:
Ozone
Production
The printer uses charging rollers in the electrophotographic process and
therefore generates no appreciable ozone gas (0
3
).
CFC Usage
Class I U.S. Clean Air Act stratospheric ozone-depleting chemicals
(chlorofluorocarbons [CFCs], for example) have been eliminated from the
manufacturing of the printer and packaging.
The printer design reduces:
Energy
Consumption
Energy usage drops from 330 watts (W) during printing to as little as 16 W
while in low-power (PowerSave) mode. This saves energy without affecting
the high performance of the printer. This product qualifies for the E
NERGY
S
TA R
Program (U.S. and Japan). E
NERGY
S
TA R
is a voluntary program
established to encourage the development of energy-efficient office
products. The E
NERGY
S
TA R
name is a registered service mark of the U.S.
Environmental Protection Agency.
As an E
NERGY
S
TA R
partner, Hewlett-Packard
Company has determined that this product meets
E
NERGY
S
TA R
Guidelines for energy efficiency.
Toner
Consumption
EconoMode uses about 50% less toner, thereby extending the life of the
toner cartridge.
Paper use
The printer’s optional duplexing feature, which provides for two-sided
printing, reduces paper usage and the resulting demands on natural
resources.
