The only movement is through the movement of the rotary cam located on the stapler unit itself, during the actual stapling of the booklet. The stitch-home-position switch (SW5) is part of the rear stitch stapler unit and senses the stapler opening and closing during stapling by the motion of the rotary drive cam. Like SW5, the stitch motor (M6) is also part of the overall stitch-stapler unit and replacement requires the replacement of saddle-stapler assembly. Error occurs when the front booklet-makerstapler stitching-home-position sensor (SW5) does not turn on when the stitch motor (rear) (M6) has been driven forward for 0.5 seconds. Also occurs when the front booklet-makerstapler stitching-home-position sensor (SW5) does not turn off when the stitch motor (rear) (M6) has been driven forward for 0.5 seconds.
