Recycling print cartridges
Since 1990, the HP Printing Supplies Returns and Recycling Program has collected millions
of used LaserJet print cartridges that otherwise may have been discarded in the world's
landfills. The HP LaserJet print cartridges and supplies are collected and bulk shipped to our
resource and recovery partners who disassemble the cartridge. After a thorough quality
inspection, selected parts are reclaimed for use in new cartridges. Remaining materials are
separated and converted into raw materials for use by other industries to make a variety of
useful products.
U.S. returns
For a more environmentally responsible return of used cartridges and supplies,
HP encourages the use of bulk returns. Simply bundle two or more cartridges together and
use the single, pre-paid, pre-addressed UPS label that is supplied in the package. For more
information in the U.S., call (800) 340-2445, or visit the HP LaserJet Supplies website at
http://www.hp.com/recycle .
Saving toner
To save toner, select the EconoMode option in your device properties settings. (For more
information, see
To use EconoMode (to save toner) .) While in EconoMode (Save Toner), the
device uses less toner on each page. Selecting this option extends the life of the print
cartridge and reduces your cost per page, but it also reduces print quality. HP does not
recommend the full-time use of EconoMode.
