HINWEIS: Set DVM to the appropriate range for the voltage.
VORSICHT! Be careful when working around electricity.
Moving parts can cause injury.
ACHTUNG: Do not use the frame as ground.
Test the Transparency sensor 1 (SN1)
1. Manually activate SN1.
TIPP: Click Subsystems, click Paper Path, and then click Horizontal Transport.

Verify that the sensor conditions are proper
1. Verify that the sensor is correctly located.
2. Verify that all of the idler rollers are correctly seated and that the drive roller surfaces are free of defects.
3. Clean the sensor and the surrounding area.
4. If the sensor has a flag actuator, check that the flag actuator has free movement.
5. Check the wire harness between the Transparency sensor 1 (SN1) and the Motion PCA (A2).

Test the voltage to the Transparency sensor 1 (SN1) on the Motion PCA (A2)
1. Disconnect J9 from A2.
2. Test the voltage to SN1 on A2: 1.15 Vdc unblocked and blocked at J9 pins 12A to 11A (GND) and 0.45VDC unblocked and 2.81VDC
blocked at pins 10A to 11A (GND).
