6.4.3 Function of Each sensor
[ 1 ] Document Sensor
Fig.6-14
The document sensor is installed on the Operation panel PBA in the Operation panel unit and detects
whether any document is loaded. When the actuator of the sensor is pushed down by the document to
turn on the sensor, the loading of a document will be detected.
In case the sensor stays on even a fixed time after the transport of the document has started, a docu-
ment jam will be assumed.
[ 2 ] Document Position Sensor
Fig.6-15
The document position sensor is installed on the Operation panel PBA in the operation panel unit and
detects whether the loaded document has been transported to before the scanning position of the CIS.
When the actuator of the sensor is pushed down by the document to turn on (or off) the sensor, the start
(or end) of scanning the document will be detected. In case the sensor stays on even a fixed time after
the transport of the document has started, a document jam will be assumed.
