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.
