Power Source: This product is intended to operate from a power source that does not apply more than 127 or 240 volts AC RMS (depending on printer model) between the supply conductors or between either supply conductor and ground. A protective ground connection by way of the grounding conductor in the power cord is essential for safe operation. Class 1 Laser Product 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. Phaser 7700 Color Printer Service Manual vii
