Protecting the environment
HP is committed to providing quality products in an environmentally sound manner. This product has
been designed with several attributes to minimize impacts on our environment.
Ozone production
The airborne emissions of ozone for this product has been measured according to a standardized
protocol* and when these emissions data are applied to an anticipated high-use scenario in an office
workspace**, HP has determined there is no appreciable amount of ozone generated during printing and
the levels are well within current indoor air quality standards and guidelines.
* Test method for the determination of emissions from hardcopy devices with respect to awarding the
environmental label for office devices with printing function; DE-UZ 205 – BAM January, 2018
** Based on ozone concentration when printing 2 hours per day in 30.6 cubic meter room with a
ventilation rate of 0.68 air changes per hour with HP printing supplies
Power consumption
Power usage drops significantly while in Ready, Sleep, or Off mode, which saves natural resources
and saves money without affecting the high performance of this product. HP printing and imaging
equipment marked with the ENERGY STAR
® logo is qualified to the U.S. Environmental Protection
Agency's ENERGY STAR specifications for imaging equipment. The following mark will appear on
ENERGY STAR qualified imaging products:

Toner consumption
EconoMode uses less toner, which might extend the life of the print cartridge. HP does not recommend
the full-time use of EconoMode. If EconoMode is used full-time, the toner supply might outlast the
mechanical parts in the print cartridge. If print quality begins to degrade and is no longer acceptable,
consider replacing the print cartridge.
