Media take-up on/off sensor

The photointerrupter-based media take-up on/off sensor detects the switch status of the media take-up unit.

When the media take-up switch is set to ON, the sensor arm transmits the sensor light, power-on the media take-up unit. When the media take-up switch is set to OFF, the sensor arm shields the sensor light, shutting down the media take-up unit.

Media take-up paper detection sensor

When the sensor light is shielded by a loop of printed paper, the media take-up motor rotates to take up the paper.
