Laser safety statement (U.S.)
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug
Administration has implemented regulations for laser products manufactured since
August 1, 1976. Compliance is mandatory for products marketed in the United States. The
printer is certified as a “Class 1” laser product under the U.S. Department of Health and Human
Services (DHHS) Radiation Performance Standard according to the Radiation Control for Health
and Safety Act of 1968. Because radiation emitted inside the printer is completely confined within
protective housings and external covers, the laser beam cannot escape during any phase of
normal user operation.
WARNING! Using controls, making adjustments, or performing procedures other than those specified in this
user guide can result in exposure to hazardous radiation.
