    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION FEEDING/DRIVE SYSTEM Outline The stitcher unit aligns the sheets coming from the finisher unit and stitches the resulting stack for delivery to the delivery tray according to the commands coming from the finisher controller PCB.

  • Page 95

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Receiving Sheets The stitcher unit receives sheets from the finisher unit and outputs them inside the vertical path in vertical orientation. The vertical path, while sheets are being output, is configured by two paper deflecting plates. The position of the sheets being output is set by the paper positioning plate so that the center of the stack matches the stapling/folding position.

  • Page 96

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Aligning the Sheets The alignment plates operate to put the sheets in order each time a sheet of paper is output to the vertical path assembly. The alignment plates are mounted at the edge of the vertical path assem- bly.

  • Page 97

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Stitching When all sheets have been output, the two stitchers stitch the stack. The stitchers are positioned so that they face the center of a stack. The two stitchers are not operated simultaneously so as to prevent the paper from wrinkling between two staples and to limit the load on the power supply.

  • Page 98

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Feeding the Stack The unit folds the stitched stack of sheets, and then feeds it to the point of delivery. This point is where the center of the stack, i.e., stapling position, matches the height of the paper pushing plate and the paper folding roller nip.

  • Page 99

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Folding/Delivering the Stack The paper pushing plate pushes against the center of the stack to move it in the direction of the paper folding rollers. In response, the paper folding rollers pick the stack along its center and fold it in two.

  • Page 100: Paper Output Mechanism

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION III. PAPER OUTPUT MECHANISM Outline The paper output mechanism serves to keep a stack of sheets coming from the finisher in place for the next steps (stapling, folding). The paper inlet is equipped with the No.1 flapper and the No.2 flapper, which operate to con- figure the paper path to suit the size of paper.

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Controlling the Movement of Sheets When the leading edge of a sheet has moved past the inlet flapper, the intermediate feed roller and the crescent roller start to move the sheet forward. The intermediate feed roller is normally not in contact with the path bed. When the leading edge of a sheet reaches the intermediate feed roller contact section, the feed plate contact solenoid (SL4S) causes the roller to come into contact with the path bed so as to move the sheet.

  • Page 109: Aligning The Sheets

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Aligning the Sheets The alignment motor (M5S) drives the alignment plates each time a sheet is output, putting both left and right edges of the sheet in order. The alignment plate motor is a 4-phase stepping motor.

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Controlling the Phase of the Crescent Roller Outline If alignment was executed with the crescent roller in contact with the stack of sheets, the result- ing friction against the roller causes the stack to move inappropriately (Figure 3-317). To prevent this problem, the phase of the roller is identified and used to determine the timing of alignment.

  • Page 114: Stitching System

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION IV. STITCHING SYSTEM Outline The stitching system “stitches” the center of an output stack with staples. To enable stitching at two locations on a stack, two stitcher units (front, rear) are used. Each stitcher unit is equipped with a stitcher motor (M7S, M6S) for drive, a stitcher home position sensor (MS7S, MS5S) for detection of position and a staple sensor (MS6S, MS4S) for detection of the presence/absence of staples.

  • Page 115

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Stitcher Unit Operation The stitcher base unit consists of two stitchers and stitcher bases. The stitchers are fixed in position, and are not designed to slide or swing. Stitching is executed by driving the rotary cam by the stitcher motor (M7S, M6S). The front and rear stitcher units are operated with a time delay so as to prevent wrinkling of paper and to limit the load applied to the power supply.

  • Page 117: Folding/delivery System

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION FOLDING/DELIVERY SYSTEM Outline The paper folding mechanism consists of a guide plate, paper folding rollers, paper pushing plate, and paper positioning plate. The guide plate is used to cover the folding rollers while sheets are output so as to prevent sheets from coming into contact with the folding rollers during output.

  • Page 118

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Controlling the Movement of Stacks When a stack has been stitched (2 points), the paper positioning plate lowers so that the stack will move to where the paper folding rollers come into contact with the stack and where the paper pushing plate is located.

  • Page 119

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Folding a Stack A stack is folded by the action of the paper folding rollers and the paper pushing plate. The paper pushing plate pushes against the center of a stack toward the roller contact section. The paper pushing plate starts at its home position and waits at the leading edge position until the stack has been drawn to the paper folding roller and is gripped for a length of 10 mm.

    CHAPTER 3 SADDLE STITCHER UNIT BASIC OPERATION Double Folding a Stack To fold a stack consisting of 10 or more A4-R or LT-R sheets, folding is executed twice for the same sheet. The paper folding rollers rotate in reverse for an equivalent of 20 mm after gripping the stack for a length of 20 mm, enabling the paper folding rollers to apply an increased degree of pressure along the crease on the stack.
