Top Sensor
The Top Sensor includes the photo-interrupter, and detects the leading edge of the sheet of paper fed by the Pick-up Roller.
When the paper is detected, the rotation direction of the Printer Motor is reversed, and the Platen Roller rotates.
The Actuator blocks the sensor as the paper passes the Top Sensor.

End Sensor (for the Thermal Transfer Film)
The End Sensor includes the photo-interrupter and the Encoder, and detects whether there is a remaining Thermal Transfer Film
that can be printed.
By monitoring the rotation angle rate of the Thermal Transfer Film, the sensor also checks the remaining amount of film.
When the sensor value is "Hight" or "Low" constantly, the Panaboard will judge the Thermal Transfer Film as empty.
