Safety information
Laser safety
This printer is certified as a Class 1 laser product under the U.S. Department of Health and Human
Services (DHHS) Radiation Performance Standard according to Radiation Control for Health and
Safety Act of 1968. This means that the printer does not produce hazardous laser radiation. Since
radiation emitted inside the printer is completely confined within protective housings and external
covers, the laser beam cannot escape from the printer during any phase of user operation.
