CHAPTER 3 SADDLE STITCHER UNIT OUTLINE OF OPERATION 2 Feeding/Drive System 2.1 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.
CHAPTER 3 SADDLE STITCHER UNIT OUTLINE OF OPERATION 2.1.1 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.
CHAPTER 3 SADDLE STITCHER UNIT OUTLINE OF OPERATION 2.1.2 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 as- sembly.
CHAPTER 3 SADDLE STITCHER UNIT OUTLINE OF OPERATION 2.1.3 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 be- tween two staples and to limit the load on the power supply.
CHAPTER 3 SADDLE STITCHER UNIT OUTLINE OF OPERATION 2.1.4 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.
CHAPTER 3 SADDLE STITCHER UNIT OUTLINE OF OPERATION 2.1.5 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.
CHAPTER 3 SADDLE STITCHER UNIT OUTLINE OF OPERATION 3 Paper Output Mechanism 3.1 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 OUTLINE OF OPERATION 3.2 Controlling the Inlet Flappers 3.2.1 Outline The two flappers mounted at the paper inlet are operated to configure the feed path according to the size of paper. The flappers are used to enable the following: 1.

CHAPTER 3 SADDLE STITCHER UNIT OUTLINE OF OPERATION 4 Stitching System 4.1 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 (M7, M6) for drive, a stitcher home position switch (SW7, SW5) for detection of position and a staple switch (SW6, SW4) for detection of the pres- ence/absence of staples.
CHAPTER 3 SADDLE STITCHER UNIT OUTLINE OF OPERATION 4.2 Stitcher Unit Operation The stitcher base unit consists of two stitchers and stitcher bases. The stitchers are fixed in po- sition, and are not designed to slide or swing. Stitching is executed by driving the rotary cam by the stitcher motor (M7, M6). 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.
