• At the end of the operation of trying to turn Off the Rear Tamper Home Sensor that was
On, the Rear Tamper Home Sensor was not detected being Off.
• The Rear Tamper Home Sensor should have turned Off and then the Rear Tamper Motor
stopped, but the Rear Tamper Home Sensor was On.
Initial Actions
• Check the Rear Tamper Home Sensor is properly installed and has no foreign object and
that the actuator is not broken.
• Power Off/ON.
Procedure
