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.
