Notices and Safety Information
Laser Notice
The printer is certified in the U.S. to conform to the requirements of
DHHS 21 CFR Subchapter J for Class I (1) laser products, and
elsewhere is certified as a Class I laser product conforming to the
requirements of IEC 825.
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.
