Bypass Tray Feed Solenoid

Troubleshooting Reference
Applicable Parts
• Front Harness Assembly, PL 4.2.11
• Bypass Tray Feed Solenoid, PL 4.3.10
• MCU PWB, PL 12.1.15
• Main Harness Assembly, PL 12.3.1
Troubleshooting Procedure
Step Actions and Questions
1. Check the Bypass Tray Solenoid operation.
Perform DC330 Component Control
page 2-26 [071-014] to check the operation of
the Bypass Tray Feed Solenoid.
Is the Bypass Tray Feed Solenoid operating
properly?
2. Check the connection between the Bypass Tray
Feed Solenoid and MCU PWB.
Are the connectors P/J4753, P/J4751, and P/J475
connected securely?
3. Check the conductivity between the Bypass Tray
Feed Solenoid and MCU PWB.
Is the connection between P/J4753 <=> P/J4751
conducting properly?
4. Check the conductivity between the Relay
Connector and MCU PWB.
Is the connection between P/J4751 <=> P/J475
conducting properly?
5. Check the voltage supply (+24VDC) to the Bypass
Tray Feed Solenoid.
Measure the voltage between the MCU PWB
GND <=> P/J475-4.
Is there a voltage (approx. +24VDC) output?
Close the Interlock Switch and check.
