supply while performing tasks that do not need electricity. Electricity can cause death or
injury. Moving parts can cause injury.
NOTE: The main PWB has 4 test points, GND, +3.3V, +5V and +24V. The location of the test
points is shown on the Main PWB PJ location illustration.
NOTE: Trays 2, 3 and 4 are identical. Check the relevant tray module.
Refer to Wiring Diagram 7, Wiring Diagram 12 and Wiring Diagram 13. Perform the following:
1. Make sure that the tray is fully home.
2. Pull out the tray. Check for obstructions behind the tray.
3. Check that the tray home position sensor actuator on the back of the tray is not missing or
damaged.
