German acoustics statement The following measurements were made in accordance with ISO 7779 and reported in conformance with ISO 9296. Acoustics 1-Meter average sound pressure, dBA Printing 51 dBA Idling 45 dBA Energy Star The EPA ENERGY STAR Computers program is a partnership effort with computer manufacturers to promote the introduction of energy-efficient products and to reduce air pollution caused by power generation. Companies participating in this program introduce personal computers, printers, monitors, or fax machines that power down when they are not being used. This feature cuts the energy used by up to 50 percent. Lexmark is proud to be a participant in this program. As an Energy Star Partner, Lexmark International, Inc., has determined that this product meets the Energy Star guidelines for energy efficiency. Laser notices 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 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. 292
