  • Page 23: Basic Construction

    Chapter 2 2.1 Basic Construction 2.1.1 Functional Construction 0003-8735 The puncher unit is optionally installed in the delivery path between the host machine and the finisher. When the paper delivered from the host machine reaches the puncher unit, it is fed by the punch feed roller. Then when the trailing edge of the paper is detected, the paper is tempo-rarily stopped and the punch axis rotates to punch holes in the trailing edge of the paper.
  • Page 24: Feed Drive System

    Chapter 2   2.2 Feed Drive System 2.2.1 Overview 0003-9479 The puncher unit is located on the feed path between the host machine and the finisher, and successively punches holes when the paper stops temporarily. The paper delivered from the host machine is fed by the punch feed roller. The punch feed roller is driven by the punch feed motor.
  • Page 25 (PI63). To stop the DC punch motor accurately at its home po-sition, the punch motor clock sensor (PI62) counts a predetermined number of clock pulses to stop the punch motor. A single punch operation is performed by rotating the punch shaft 180° from its home position. Five light sensors (photosensor PCB) are located at the upper side of the inlet paper feed path of the puncher unit and a set of five LEDs (LED PCB) are located at the lower side.

    Chapter 2   Punch controller PCB (1/2) PTR1 LED1 Punch controller PCB (2/2) F-2-2 2.2.3 Punch Operation 0003-4699 The hole puncher is driven by the punch motor (M61), and its position is monitored by the punch home position sensor (PI63). The hole puncher makes a single round-trip movement (punching) as the punch shaft rotates 180° from home position.
  • Page 27 Chapter 2 At the home position, the punch home position sensor is ON. Punching of the first sheet ends when the punch shaft has rotated in the forward direction 180°, and the state of the punch home position sensor has changed from OFF to ON.

To punch three holes, the 2-hole puncher is moved reciprocally in the escape direction (hole puncher rise direction). The following illustrates punching when two sheets are punched with two holes.

    Chapter 2 [punch shaft stopped/ [punch shaft is rotated 90˚ [punch shaft is rotated 180˚ home position] in the reverse direction/ in the reverse direction/ hole punched] punch operation completed] F-2-7 When two holes are punched, the 3-hole puncher is fed reciprocally in the escape direction (hole puncher rise direction) as shown below.

  • Page 31 Chapter 2 Punch F-2-11 4) When punching ends, drive of the punch feed motor (M63) is started, the horizontal registration motor (M62) is operated in the reverse direction, and the punch slide unit is returned to its home position where it comes to a stop. 5) Even if paper to be punched continues to arrive, the punch slide unit returns to its home position for each arriving sheet, and steps 1 to 4 are repeated.
