FOLDING/THREE-FOLDING ( Q5687A ONLY) Q5686A/Q5687A 5.2.3 Three-folding gate control The three-folding gate switches between the folding/stitch-and-fold path and the three-folding path. The three-folding gate is driven by the three-folding gate solenoid (SD706). A. Second folding operation of the three-folding The three-folding gate solenoid (SD706) drives the three-folding gate [1] to switch the paper path to the three-folding path and guide the paper [3] discharged from the folding roller [2] to the three-folding stopper [4].
A sheet of paper that runs up against the three-folding stopper is made into a loop [5] which is drawn in II UNIT EXPLANATION folding roller and the three-folding roller, is folded to make the second folding and then discharged to the between the folding roller and the three-folding roller [6]. This loop of paper, which is being pressed by the booklet tray [7]. The folding position of the second folding depends on the position of the three-folding stopper. [2] SD706 [3] [1] [5] [4] [7] [6] [6] B.
Three-folding gate control When the booklet stopper stops at the three-folding position, the three-folding gate solenoid (SD706) turns on to drive the three-folding gate and switch the paper path to the three-folding stopper. A specified period of time after the folding exit sensor (PS725) detects the trailing edge of the paper bun- dle, SD706 turns off. 2-37
