CDRH regulations
The Center of Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration imple-
mented regulations for laser products on August 2, 1976. These regulations apply to laser products manu-
factured after August 1, 1976. Compliance is mandatory for products marketed in the United States. A label
indicating compliance with the CDRH regulations must be attached to laser products marketed in the
United States.
Ozone concentration
The printers generate ozone gas (O
3
) which may concentrate in the place of installation and cause an
unpleasant smell. To minimize concentration of ozone gas to less than 0.1 ppm, we recommend you not to
install the printer in a confined area where ventilation is blocked.
