SAFETY INFORMATION
This printer is a page printer which operates by means of a laser. There is no possibility of danger from
the laser, provided the printer is operated according to the instructions in this manual provided.
Since radiation emitted by the laser is completely
coti-ined
within protective housings, the laser beam
camot escape from the machine during any phase of user operation.
For United States Users:
[Laser Safety]
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. This means that the printer does not
produce hazardous laser radiation.
[CDRH
The Center for Devices and Radiological Health
Regulations]
(CDRH)
Administration implemented regulations for laser products on August 2,1976. Compliance is mandatory for products marketed in the United States. The label shown below
indicates compliance with the
CDRH
regulations and must be attached to
marketed in the United States.
‘WARNING: Use of controls, adjustments or performance of procedures other
than those specified in this manual may result in hazardous radiation exposure.
