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 60825-1.
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.

Energy Star
The EPA ENERGY STAR Office Equipment program is a partnership effort with office equipment manufacturers
to promote the introduction of energy-efficient products and to reduce air pollution caused by power
generation.
