Troubleshooting Procedure
Step Actions and Questions Yes No
1. Check the Feeder Motor operation.
Perform DC330 Component Control on
page 2-26 to check the operation of the Feeder
Motor:
• Tray 2 [071-018]
• Tray 3 [071-020]
• Tray 4 [071-022]
Is the Feeder Motor operating properly?
Replace the MCU PWB
(REP 12.4 MCU PWB
on page 4-206).
Go to step 2.
2. Check the installation of Feeder Motor.
Manually rotate the Feeder Motor.
Does the Motor rotate?
Reinstall the Feeder
Motor (REP 15.20
Option Drive Assembly
on page 4-283).
Go to step 3.
3. Check the connection between the Feeder Motor
and Feeder PWB.
Are the connectors P/J422, P/J221, and P/J222
connected securely?
Go to step 4. Connect the
connectors P/J422,
P/J221, and P/J222.
4. Check the conductivity between Feeder Motor
and Feeder PWB.
Are the connections between P/J221 <=> P/J422
and P/J222 <=> P/J422 conducting properly?
Go to step 5. Replace the Option
Left Feeder Harness
Assembly.
5. Check the voltage supply (+24VDC) to the Feeder
Motor.
Measure the voltage between the Feeder PWB
GND <=> P/J422-6.
Is there a voltage (approx. +24VDC) output?
Close the Interlock Switch and check.
Replace the Option
Drive Assembly (REP
15.20 Option Drive
Assembly on
page 4-283).
Replace the Feeder
PWB (REP 15.22
Feeder PWB on
