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 photocopier, 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.
