CLASS 1 LASER PRODUCT
The Phaser 5400 Laser Printer is 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.
