Theory of Operation Ver2.0 Sep.2006
B. Control
(1) Small size paper (313 mm or less)
For the small size paper, the bundle arm assist motor (M26) rotates in the forward direction when the main body
start signal [1] turns ON to drive the bundle arm assist plate at the home position to the position at the bundle
arm assist upper limit sensor (PS39) [2]. After a specified period of time, M26 rotates in the reverse direction to
drive the bundle arm assist plate from the upper limit position to the standby position in accordance with the
paper size [3] and stands by for the paper.
Then, M26 rotates in the forward direction to push up the fore edge side of the paper [6] for assisting the bundle
arm to be inserted under the fold line of the paper. The operation timing [6] of M26 is different between in the
multi center folding mode and in the saddle stitching mode.
• Multi center folding mode: When the bundle arm is contacted with the guide plate of the stapler section [4]
by the bundle arm rotation motor (M22).
• Saddle stitching mode: When the clincher moves downward [5] at the end of the stapling operation.
M26 rotates in the forward direction to assist the bundle arm to convey the paper [7] after a specified period.
Then the bundle arm assist plate go back to the standby position and stands by for the subsequent set [8].
