2.1.4. Precautions for Handling Lasers
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 path of the
laser.
2. Before servicing the photocopier, take off any watches, rings, or other metallic objects that you may be
wearing. (This is to avoid the danger of the laser entering the eye by reflecting off the metallic objects
being worn.)
Since the laser beam cannot be seen with the naked eye, please follow the above precautions for
maximum safety.
