Bundle arm assist control

A. Mechanism
The bundle arm assist mechanism is the mechanism to assist the paper conveyance of the bundle arm rotation
drive to be conducted without fault. It pushes up the fore edge side of the paper [6] with the bundle arm assist
plate [4] to tilt it to the front.
The bundle arm assist motor (M26) [2] drives the bundle arm plate [4] via the belt.
The bundle arm assist upper limit sensor (PS39) [1] detects the upper home position and the bundle arm assist
home sensor (PS38) [3] detects the lower home position.
The bundle arm assist plate [4] waits at the position 5 mm below the fore edge side of the paper during standby.
To keep the error to a minimum, the small size paper (313 mm or less) and the large size paper (314 mm or
more) are moved to the standby position from the position of PS39 and PS38 respectively since the standby
position for the paper is positioned by the driving time of M26 (DC brush motor).
In the bundle arm assist operation, the fore edge side of the paper is pushed up 35 mm (or until PS39 turns ON).
