Energy Star; Laser Notice - Lexmark E320/E322 User Reference Manual

Energy Star

The EPA ENERGY STAR Computers program is a partnership effort with computer manufacturers to
promote the introduction of energy-efficient products and to reduce air pollution caused by power
generation.
Companies participating in this program introduce personal computers, printers, monitors, or fax
machines that power down when they are not being used. This feature will cut the energy used by up to
50 percent. Lexmark is proud to be a participant in this program.
As an Energy Star Partner, Lexmark International, Inc. has determined that this product meets the
Energy Star guidelines for energy efficiency.

Laser notice

The printer is certified in the U.S. to conform to the requirements of DHHS 21 CFR Subchapter J for
Class I (1) laser products, and elsewhere is certified as a Class I laser product conforming to the
requirements of IEC 825.
Class I laser products are not considered to be hazardous. The printer contains internally a Class IIIb
(3b) laser that is nominally a 5 milliwatt gallium arsenide laser operating in the wavelength region of
770-795 nanometers. The laser system and printer are designed so there is never any human access
to laser radiation above a Class I level during normal operation, user maintenance, or prescribed
service condition.
