Laser notice
The printer is certified in the U.S. to conform to the requirements of DHHS 21 CFR Chapter I, 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 10 milliwatt gallium arsenide laser operating in the wavelength of 787-800 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.
