Actuator return failure, or improper installation.
2. Perform the Tray Feed Sensors test in Diagnostics.
3. When 3TM is connected, check the connection between the Tray 2 Feed Out
Sensor J108-1 and the Tray Module PWB J549-A3 for short circuit.
4. When STM is connected, check the connection between the Tray 2 Feed Out
Sensor J108-1 and the STM PWB J548-3 for short circuit.
5. Check the connection between the Motor Drive PWB J509-6 and the TM Relay
PWB J801-10 for short circuit.
6. When 3TM is connected, check the connection between the TM Relay PWB
J800-A6 and the Tray Module PWB J541-6 for short circuit.
7. When STM is connected, check the connection between the TM Relay PWB
J800-A6 and the STM PWB J541-6 for short circuit.
8. If no problems are found, replace the following parts in sequence:
