4.3.5 Paper Feed Sensor
Feed direction
The paper feed sensor is installed on the base block and detects the transport status of record-
ing paper to check for paper jams.
When the actuator of the sensor is pushed down by the recording paper to turn on the sensor,
the recording paper being transported over the sensor will be detected. Then, when the record-
ing paper passes the sensor to turn off the sensor, it will be judged that the recording paper has
been transported normally. In case the sensor stays on even a fixed time after the sensor has
been turned on, a paper jam will be assumed.
4.3.6 Paper Exit Sensor
Feed direction
The paper exit sensor is installed on the fuser and detects the transport status of recording
paper to check for paper jams.
When the actuator of the sensor is pushed down by the recording paper to turn on the sensor,
the recording paper being transported over the sensor will be detected. Then, when the record-
ing paper passes the sensor to turn off the sensor, it will be judged that the recording paper has
been transported normally. In case the sensor stays on even a fixed time after the sensor has
been turned on, a paper jam will be assumed.
