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 IDO Duplex Media sensor (SN16)
1. Manually activate SN16.
TIPP: Click Subsystems, click Paper Path, and then click IDO Sensors, Solenoids, LEDs.
Does the sensor state change?
No Yes

Check the following
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 IDO Duplex Media sensor (SN16) and the Motion PCA (A2).

Test the voltage to the IDO Duplex Media sensor (SN16) on the Motion PCA (A2)
1. Disconnect J4 from A2.
2. Test the voltage to SN16 on A2: 3.25 Vdc unblocked, 0.08 Vdc blocked at J4 pins 9B to 10B and 1.18 Vdc unblocked and blocked at
pins 8B to 10B.
