1. After taking the unit apart, do not attempt to operate the machine.
2. When operating the machine with covers removed, be careful and avoid clothing from being caught by
moving components.
3. While the electricity is applied to the unit, do not connect nor disconnect the connectors on any PC
Board.
4. When handling the drum, follow the precautions listed in section 3.3..
5. Ensure to use correct screws.
6. Use toothed lock washers for the installation of ground wires to ensure electrical continuity.
7. To reassemble, reverse the sequence of disassembly, unless otherwise specified.
8. Blown fuses should only be replaced with fuses of the same specified rating.
3.1.4.
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.
