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 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. The printer has a non-serviceable printhead assembly that contains a laser
with the following specifications:
Class: IIIb (3b) AlGaAs
Nominal output power (milliwatts): 25
Wavelength (nanometers): 755–800
