Transfer Belt Sensor

The transfer belt sensor [A] works as the detection sensor during machine
initialization, and works as the position sensor during machine operations.
Before machine initialization, the lower end of the transfer belt is in the home
position. When initialization starts, the transfer belt contact motor lifts the lower end
until the actuator has passed the sensor, and lowers it to its home position. This
action actuates the sensor in a certain pattern.
The table lists the sensor actuation patterns.
Initialization
Operation
