C. Bundle arm control
The bundle arm motor (M10) rotates in the reverse direction when the main body start signal [1] turns ON and
moves the bundle arm to the appropriate position in accordance with the paper size.
The bundle arm rotation motor (M22) rotates in the forward direction to rotate the bundle arm to the stapling
section [3] after a specified period of time since the folding sensor /2 (PS44) detects the trailing edge of paper of
the last set. It stops the bundle arm in an upright position [4] when the bundle arm rotation home sensor (PS31)
turns OFF.
Then, M22 rotates again [5] to drive the bundle arm until it is contacted with the guide plate on the stapling sec-
tion [6]. The timing for M22 to restart the rotation [5] is different between in the multi center folding mode and in
the saddle stitching mode.
• Multi center folding mode: When the saddle stitching press home sensor (PS27) detects the saddle stitch-
ing hold /Up has been moved to the its upper position.
• Saddle stitching mode: After a specified period of time since the clincher up down home sensor (PS26)
detects that the clinchers are contacted with the staplers.
M10 inserts the tip of the bundle arm under the fold line of the paper [7] when the bundle arm assist motor (M26)
starts the assisting operation by pushing up the trailing edge of paper at the back side and M10 stops after a
specified period of time [8].
M22 rotates in the reverse direction to convey the paper to the bundle clip section when M10 stops [8]. It stops
after a specified period of time since PS31 turns ON.
M10 rotates in the forward direction to pull out the bundle arm from the paper and take shelter it from the con-
veyance path [11] after a specified period of time since the bundle clip starts to catch the paper [10]. M10 stops
when the bundle arm home sensor (PS32) turns ON [12].
M10 rotates in the reverse direction to go back the bundle arm to its standby position [13] for the subsequent
set after a specified period of time since it stops.
