TROUBLESHOOTING Procedure for Troubleshooting 78
Confidential
3.1.3 Precautions in Performing Troubleshooting Work
1. Be sure to unplug the power cord before starting troubleshooting work unless
instructed to plug it in.
2. If you perform work with the power turned ON, covers removed, and the interlock
and safety switches turned ON, be sure to disconnect the connector (P/J12) on the
PWBA MCU from the ROS ASSY, except when its connection is required.
3. If you perform work with the power turned ON, covers removed, and the interlock
and safety switches turned ON, be careful of a high voltage from HVPS.
4. When touching any hot surfaces, take care not to burn yourself.
5. Wear a wrist strap to discharge static electricity from your body.
Never touch any live parts unnecessarily when the power is on.
The power switch/inlet part is alive even when the power switch is
turned OFF. Take care not to touch any live parts.
If you perform work with the power turned ON, covers removed,
and the interlock and safety switches turned ON, there is a danger
of the laser beam being emitted from ROS ASSY. Be sure to
disconnect the ROS ASSY connector (P/J12), except when its
connection is required.
If you perform work with the power turned ON, covers removed,
and the interlock and safety switches turned ON, never touch the
high-voltage power supply and any other high voltage output part
as a high voltage may be output from HVPS.
