    Shift Tray SHIFT TRAY 2.4.1 UP/DOWN MOTION The shift tray motor [A] moves the tray up and down. The upper limit switch [B] detects when the tray moves up too far, and cuts power to the shift tray motor. The shift tray position sensor [C] checks when the tray (or the top of the stack) is at the correct height to receive paper.

    Shift Tray 2.4.2 SIDE-TO-SIDE MOTION The shift motor [A] moves the shift roller [B] from side to side. The shift motor HP sensor [C] detects when the mechanism is at home position. The upper transport motor rotates the shift roller. When shift mode is used, the shift motor turns on after each page is fed out.

  • Page 785: Booklet Tray

    Booklet Tray BOOKLET TRAY The sensor actuator arm [A] rests on the top of the stack of stapled booklets as they are output to the lower tray. A flap depressor [B] keeps the open ends of the booklets down. The front booklet tray full sensor [C] and rear booklet tray full sensor [D] detect when the tray is full of booklets.

  • Page 788: Jogger Unit

    Jogger Unit JOGGER UNIT The jogger is used in corner-staple mode and in booklet mode. For each sheet of paper when it arrives in the staple tray, the following is done. The jogger motor [A] drives the jogger fences [B]. The positioning roller solenoid moves the positioning roller [C] onto the top of the sheet.

  • Page 789: Exit Guide Plate, Paper Feed Out

    Exit Guide Plate, Paper Feed Out EXIT GUIDE PLATE, PAPER FEED OUT The exit guide plate [A] opens when a stapled stack is fed out. Also it opens every time a sheet is fed to the staple tray, to prevent the paper running into the exit roller during stacking.

  • Page 790: Stapler Unit Movement

    Stapler Unit Movement STAPLER UNIT MOVEMENT The machine has only one stapler [A]. It does stapling for booklets and for corner stapling. The stapler unit motor [B] moves the stapler from side to side. The stapler unit HP sensor [C] detects when the stapler unit is at home position. In corner staple mode, at the start of the job, the stapler moves to the position where the stapler will be inserted.

  • Page 791: Stacking For Booklet Stapling

    Stacking for Booklet Stapling STACKING FOR BOOKLET STAPLING 2.9.1 OVERVIEW There are two stoppers near the stapler unit. These stoppers hold the stack of paper in the correct position during stacking. The stoppers are called ‘stopper S’ and ‘stopper L’. Stopper S is used for legal size paper, or shorter than 8.5 x 14 inches.

  • Page 792: Longer Than 8.5 X 14 Inches

    Stacking for Booklet Stapling When the stack is complete, stopper S moves away [D], and the machine feeds the stack to the correct position for stapling. To do this, the upper clamp roller motor [E] rotates the upper clamp roller. 2.9.3 LONGER THAN 8.5 X 14 INCHES At the start of the set, the stapler moves to the center position.

  • Page 794: Moving The Stack To The Folding Position

    Moving the Stack to the Folding Position 2.10 MOVING THE STACK TO THE FOLDING POSITION First, the upper clamp roller feeds the stack down after the stack has been stapled. When the lower clamp roller [A] catches the stack, the upper clamp roller stops, and the lower clamp roller feeds the stack down.

  • Page 795: Folder

    Folder 2.11 FOLDER 2.11.1 OVERVIEW The fold plate pushes the stack into the nip between the fold rollers. The fold rollers feed out the stack, then reverse to feed it back in again. Then, the fold rollers feed the stack out of the folder, to the booklet tray.

  • Page 797: Punch Unit

    Punch Unit 2.12 PUNCH UNIT 2.12.1 OVERVIEW OF OPERATION Skew Correction Before Punching The finisher entrance roller corrects for paper skew and then the punch unit moves across to punch the holes at the correct position. Each sheet is punched one at a time. Paper feeds out of the copier.
  • Page 798 Punch Unit Punch Unit Position Correction These operations (skew correction before punching, and punch unit position correction) increase the accuracy of the punch alignment. The trailing edge of the sheet passes the finisher entrance sensor [A]. The paper position slide unit moves the paper position sensor [B] forward to the edge of the paper.

  • Page 799: Paper Position Detection

    Punch Unit These SP codes adjust the punch hole alignment: SP6128 Adjusts the punch positions in the direction of paper feed. SP6129 Adjusts the punch position perpendicular to the direction of feed. For more, see Section "5. Service Tables". 2.12.2 PAPER POSITION DETECTION The paper position sensor slide motor [A] extends and retracts the paper position slide that holds the paper position sensor [B].

  • Page 800: Punch Unit Movement

    Punch Unit 2.12.3 PUNCH UNIT MOVEMENT The punch movement motor [A] extends and retracts the punch unit to put it at the correct position for punching. The punch movement HP sensor [B] detects the position when it retracts, switches off the punch movement motor, and stops the punch unit at its home position.

  • Page 801: Punch Hopper Mechanism

    Punch Unit The timing for 2-hole punching [E] is different from 3-hole punching [F]. When the punch unit is at the punching position, the punch motor turns until the encoder detects the starting position for 2-hole or 3-hole punching. This is the ‘1’ position in the diagrams (the first diagram is for 2-hole punching, and the second diagram is for 3-hole punching).
