Cap sensor
The photo inerrupter-based cap sensor detects the status of the caps on the purge unit.
The sensor determines that the cap is closed when the rotary flag, which operates in conjunction with the cap cam shaft, cuts off the sensor light. The other
states are determined by the number of pulses from the pulse motor based on the timing when the sensor light is cut off.
