Error Troubleshooting
Step Check
4 Check the power to the Feed Clutch (+24 VDC)
Close the interlock switch(es), and check if the voltage
between the MCU Board ground and the P/J39-3 pin is about
+24 VDC.
Regi Clutch (PL15.1.8)
Step Check
Possible causative parts:
• Regi Clutch (PL15.1.8)
• Regi Harness Assembly (PL15.2.8)
• MCU Board (PL18.1.13)
1 Check the Regi Clutch operation
Execute Digital Output diagnostic test 071-010, and check
the Regi Clutch operation.
Does the Regi Clutch function normally?
2 Check the Regi Clutch connection
Check the connection between the Regi Clutch and the MCU
Board.
Are P/J234 and P/J23 connected securely?
3 Check the Regi Clutch resistance value
Turn off the power, take off the Regi Clutch, and check the
wire wound resistance between both terminals.
Is the wire wound resistance value 240 ohm (20 degrees C)?
4 Check the power to the Regi Clutch (+24 VDC)
Close the interlock switch(es), and check if the voltage
between the MCU Board ground and the P/J23-1 pin is about
+24 VDC.
