Laser safety statement
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. This 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. Since radiation emitted inside this 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 manual may result in exposure to hazardous
radiation.
