Laser Notice - Lexmark Optra Optra T User Manual

Laser Notice

The printer is certified in the U.S. to conform to the requirements of DHHS 21 CFR Sub-
chapter 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 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.
