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 12 milliwatt gallium arsenide laser operating in the wavelength of 650-670
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.
