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
