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) AlGaAs
laser that is nominally 25 milliwatts operating in the wavelength region of 770–800 or 775–800 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.
