Chapter 2 Humidity sensor The humidity sensor detects the temperature and relative humidity around the printer to implement head height adjustment, maintenance jet control, waste ink evaporation calculation and suction fan control on the basis of the temperature and relative humidity thus measured. 2.5.6 Media take-up Unit 0013-8115 Media take-up on/off sensor OFF ON Media take-up paper detection sensor F-2-34 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 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.
