Paper surface detection at paper's lead edge
The surface of the paper's lead edge is detected by the paper surface sensor 1, the paper
surface sensor 2 and the intermediate paper surface sensor.
The up/down movement of the paper surface link rotates the paper surface sensor flag (which
is engaged with the paper surface link) to turn ON/OFF each sensor.
There is gap toward the rotation direction in the positioning of each paper surface sensor and
paper sensor flag. The height of the paper surface at the lead edge is identified by this gap.

The paper surface sensor 2 is also used for control to detect the presence of paper.

Paper detection in the paper's trail edge
In the paper's trail edge side is detected by the trailing edge sensor 1 and trailing edge sensor
2 located in the trail edge guide plate.
The paper surface sensor flag, is engaged with the retaining plate, which is in contact with the
paper, to turn ON/OFF each sensor.
There is gap in the height of the front and rear side of the trailing edge sensors and paper
surface sensor flag. The height of the paper surface at the trail edge is identified by this gap.
