SAFETY INFORMATION
Laser Safety (110-120V Model only)
This printer is certified as a Class 1 laser product under the US Department of Health and Human
Services (DHHS) Radiation Performance Standard according to the Radiation Control for Health
and Safety Act of 1968. This means that the printer does not produce hazardous laser radiation.
Since radiation emitted inside the printer is completely confined within the protective housings and
external covers, the laser beam cannot escape from the machine during any phase of user
operation.

The Center for Device and Radiological Health (CDRH) of the US Food and Drug Administration
implemented regulations for laser products on August 2, 1976. These regulations apply to laser
products manufactured from August 1, 1976. Compliance is mandatory for products marketed in
the United States. The label shown below indicates compliance with the CDRH regulations and
