The Scanner Tests screen shows the sensor name, sensor state (active or inactive), and the number of times
the sensor has been toggled (activated).
1. From the Home screen on the product control panel, scroll to and touch the Administration button.
2. Open the following menus:
●
Troubleshooting

3. Touch the sensor name on the Scanner Tests screen to display a sensor location graphic on the control-
panel display.
4. Activate the desired sensor, and then check the control-panel display to verify the sensor state (active
or inactive).
●
The State virtual LED next to the sensor number and sensor name illuminates green when the
sensor is active.
●
The Toggle virtual LED next to the sensor number and sensor name illuminates green after the
sensor is activated and increments by one each time the sensor is interrupted (activated or
deactivated).
For example, opening the flatbed cover increments the Flatbed cover Toggle item count two times
—once when the door is opened, and once when the door is closed.
5. Touch the Reset Sensors button to reset the Toggle count item.
