Paper Exit Sensor
Reverse Unit Open/Closed Sensor
Chassis Cover Open/Closed Sensor
<2> Paper Exit Sensor (HI_SEN)
HI_SEN uses the photointerrupter integrated with an LED and a pho- totransistor.
The sensor detects a sheet with the lever actuator interrupting the light path of the photointerrupter.
The signal is transmitted to the CPU
The signal input to the CPU follow the logic: "L" when a sheet is detected, "H" when not detected.
R39 is a current limiting resistor for the LED. R34 is a load resistor for the sensor.
<3> Reverse Unit Open/Closed Sensor (HYK_SEN)
HYK_SEN uses the photointerrupter integrated with an LED and a phototransistor.
The sensor detects state of the reverse unit with the lever actuator interrupting the light path of the photointerrupter.
