2 a. Test the voltage of each Sensor using ground (GRD = Chassis) to the correct
pin on each connector. See the Sensor Location and Voltages table on the
next page).
b. Block a slot Sensor with a card.
c. Cover a reflective Sensor with a card.
3 a. Troubleshoot the Ribbon Sensor by using the RibbonTraq marks on the
Ribbon and Film to cover the Ribbon and Film Sensors. (Note: The numbers
indicate the location on J16, as shown in the Sensor Location and
Voltages table on the next page).
