Shock Hazard
This symbol indicates the presence of potentially
hazardous voltages.
CLASS 1 LASER PRODUCT
The Laser Printers are certified to comply with
Laser Product Performance Standards, set by the
U.S. Department of Health and Human Services,
as a Class 1 Laser Product. This means that this
is a class of laser product that does not emit
hazardous laser radiation; this is possible only
because the laser beam is totally enclosed during
all modes of customer operation.
The laser and output of the laser scanner unit
produces a beam that, if looked into, could cause
eye damage. Service procedures must be
followed exactly as written without change.
When servicing the machine or laser module,
follow the procedures specified in the manual and
there will be no hazards from the laser.
Laser (FDA): Any laser label visible to service
must be reproduced in the service manual with
location shown or indicated. Safe working
procedures and clear warnings concerning
precautions to avoid possible exposure must also
be included.
The following laser symbol will be displayed at the
start of any procedure where possible exposure to
the laser beam exists.
Each Network Laser Printer has two laser warning
labels. The first label is located on the top of the
Laser Unit. The second is located behind the
right-hand cover. These labels are visible when
the covers are removed. See the illustrations on
the next page for the location of the labels.

WARNING
Invisible laser radiation when cover open and
interlocks defeated. Avoid exposure to beam.
