Laser Notice
The printer is certified in the U.S. to conform to the requirements of 21CFR, Chapter 1, 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.
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.
Energy Star
ENERGY STAR ® Compliance
Certain configurations of Dell printers comply with the requirements set forth by the Environmental
Protection Agency (EPA) for energy-efficient printers. If the front panel of your printer bears the ENERGY
STAR
® Emblem, your original configuration complies with these requirements and all ENERGY STAR ® power
management features of the printer are enabled.
Any Dell printer bearing the ENERGY STAR ® Emblem is certified to comply with EPA ENERGY STAR ®
requirements as configured when shipped by Dell. Any changes you make to this configuration (such as
installing additional expansion cards or drives) may increase the printer's power consumption beyond the
limits set by the EPA's ENERGY STAR
® Computers program.
