[ 5 ] Paper Exit Sensor
Fig.6-18
The paper exit sensor is installed on the fuser and detects the exit status of the printed recording paper.
A load is given to the actuator of the sensor by the spring. When the RX cover is open, the actuator is
pushed up to turn on the sensor forcibly. When it is closed, the spring is pushed down by the cover
plate to move the actuator freely. This turns off the sensor and the recording paper can be detected.
When the actuator of the sensor is pushed down by the recording paper to turn on the sensor, the trans-
port of the recording paper over the sensor is detected. Then, when the recording paper is further trans-
ported and the sensor returns to the OFF status, the exit of the recording paper is assumed. In case the
sensor does not return to the OFF status even a fixed time after the sensor is turned on, a recording
paper jam is assumed.
