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: 2014.
Class I laser products are not considered to be hazardous. The printer contains internally a Class IIIb (3b) AlGaInP
laser that is nominally 15 milliwatts operating in the wavelength region of 650–670 nanometers and enclosed
in a non-serviceable printhead assembly. 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
conditions.
