Safety Information

Product and Laser Safety

HP printers are UL 1950 listed, CSA 22.2 950 certified, and
manufactured in accordance with DIN IEC 950. The printers are
certified as "Class 1" laser products 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. The printers do not produce hazardous laser
radiation.
Since radiation emitted inside the printer is completely confined
within protective housings and external covers, the laser beam
cannot escape during any phase of normal user operation.
The Center for Devices and Radiological Health (CDRH) of the
U.S. 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.
In accordance with West German standard
N o t e
VDE0836 (VDE-Bestimmung fur die Elektrische
Sicherheit von Lasergeraten und Anlagen), two
servicemen are required to service each unit.
Since the laser beam is invisible, the label on the following page
is attached to the Laser Scanner Cover inside the printer where
there is danger of exposure to laser radiation.
Never service or operate the printer with the
C a u t i o n
protective cover removed from the laser scanner
assembly. The reflected beam, although invisible,
can damage your eyes.
