SAFETY OF LASER BEAM
1. Safety of laser beam
This copier has been certified by the manufacturer to Class 1 level under the radiation performance
standards established by the U.S. DHHS (Department of Health and Human Services) in 1968.
This indicates that the product is safe to use during normal operation and maintenance. The laser
optical system, enclosed in a protective housing and sealed within the external covers, never
permits the laser beam to escape.
2. The CDRH Act
A laser-product-related act was implemented on Aug. 2, 1976, by the Center for Devices and
Radiological Health (CDRH) of the U.S. Food and Drug Administration (FDA). This act prohibits the
sale of laser products in the U.S. without certification, and applies to laser products manufactured
after Aug. 1, 1976.
The label shown below indicates compliance with the CDRH regulations and must be attached to
laser products marketed in the United States.
On this copier, the label is on the rear.
