The Phaser

7700 Color 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 to avoid any 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.
