Alignment / Shifting Operation

The paper stacked on the processing tray is aligned in the width direction by the front and
rear alignment plates. Then, the paper is shifted to the position where it is delivered to the
stack tray.
The front alignment plate is driven by the front alignment motor (M4) and the rear alignment
plate is driven by the rear alignment motor (M5). The home positions of the front and rear
alignment plates are detected by the Front Alignment Plate HP Sensor (S4) and Rear
Alignment Plate HP Sensor (S5).
