The Front/Rear alignment motors (FNM3/FNM4) operate to move the front and rear alignment plates, thus aligning the paper in the width direc-
tion.(In the illustration below, paper is aligned with reference to the central reference position.) Operations described in steps (1) to (3) are
repeated for each sheet.

Outline
The paper stacked on the processing tray is aligned in the width direction by the front and rear alignment plates.
Then, the paper is delivered to the delivery tray.
When shift sort is specified, the paper stacked on the processing tray is aligned to the front or rear and shifted to sort the paper stack.
The front alignment plate is driven by the Front alignment motor (FNM3) and the rear alignment plate by the Rear alignment motor (FNM4). The home
positions of the alignment plates are detected by the Front alignment plate home position sensor (FNPS4) and Rear alignment plate home position
sensor (FNPS5).
positions of the alignment plates are detected by the Front alignment plate home position sensor (FNPS4) and Rear alignment plate home position
sensor (FNPS5).
The relationship between operation modes and alignment positions is summarized in the following table.

alignment plate does not reach the end of the
paper. Therefore, alignment is made at +8 mm
from the end of the paper for the front and rear.
