Abstract:
A sensor system includes an LED configured to emit light to a recording medium and a light-receiving sensor configured to receive a transmitted light that has passed through the recording medium after having been emitted from the LED to the recording medium. An emitting optical axis of the LED is away from a perpendicular receiving optical axis of the light-receiving sensor.
