Printer Notices

Laser Notice

The printer is certified in the U.S. to conform to the requirements of DHHS 21 CFR Sub-

chapter 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.
