Laser Handling Precautions The optical laser system employed by this photocopier is completely sealed by a protective housing, and an external cover. Therefore, the laser beam will not stray or leak during photocopying operation. However, when servicing the photocopier, take the following precautions: 1. Do not insert any screwdrivers, or other tools that have high reflective properties into the laser's path. 2. . Before servicing the machine, remove watches, rings, or other metallic objects that you may be wearing. (This is to avoid the danger of the laser striking the eye by reflecting off the metallic objects being worn.) Since the laser beam cannot be seen with the naked eye, for maximum safety, please follow the above precautions.
