LASER SAFETY

This LBP printer is certified as a Class 1 laser product under the U.S. Department of Healthand Human Services (DHHS) Radiation Performance Standard according to the Food, Drugand Cosmetic Act of 1990. This means that the LBP printer does not produce hazardous laserradiation.

Since radiation emitted inside the LBP printer is completely confined within protectivehousing and external covers, the laser beam cannot escape from the LBP printer duringany phase of user operation.

CDRH REGULATIONS

The Center for Devices and R&ological Health (CDRH) of the U.S. Food and DrugAdministration implemented regulations for laser products on August 2, 1976. These

regulations apply to laser products manufactured from August 1, 1976. Compliance ismandatory for products marketed in the United States. The label shown in the figureindicates compliance with the CDRH regulations and must be attached to laser productsmarketed in the United States-.
