Sensor Voltage Measurement
Sensors play an important role in monitoring and tracking the flow of the media inside of machine. A majority
of stall conditions could be sensor related. Therefore, a digital multi-meter (DMM) is used for measuring the
voltage reading of the sensors, and assuring proper alignment.
1. Set DMM to 20 at the DVC section.
2. Using the two probes of the DMM to get voltage, one probe placed at the chassis ground of the system,
while the other one probe pin 1 of the sensor connector on the interface board.
3. Covering the sensor, the reading of DMM should be less than 0.2V.
4. Uncovering the sensor, the reading of DMM should be more than 4.5V.
5. Mark Reading Sensors

The range of sensor’s voltage reading is greater than 4.5V or less than 0.2V has the best state for the sensor to
monitoring the media movement. The sensor connector on the sensor board has three pins. The first pin is for
signal of sensor voltage reading measurement. The second pin is for VCC (5V). The third pin is for ground.
Some sensors connector is 4-pin, the 3
rd
pin is empty; the 4
th
pin will be common ground.
