FRU Action
1 Pickup arm assembly Check to make sure the pickup arm is correctly installed. If not
installed correctly, reinstall properly.
If installed correctly, check the pickup arm assembly for any signs of
damage or broken parts. If a problem is found, replace the pickup
arm assembly.

Pickup arm solenoid Turn the power off, disconnect CN5 on the motor driver card.
Measure the resistance between C5-1 and CN5-2. The resistance
should measure approximately 41.0 ohms. If correct, go to step 5.
If incorrect, disconnect the solenoid from the solenoid cable on the
front side of the ADF near the solenoid, and measure the resistance
between pins 1 and 2 on the cable attached to the solenoid. The
resistance should measure approximately 41.0 ohms. If incorrect,
replace the solenoid assembly. If correct, replace the ADF assembly.
