  • Page 25: Feed Drive System

    2. Technical Explanation Feed Drive System Outline This puncher unit is installed in the feed inlet unit inside the finisher. It punches holes in paper fed from the host machine according to the puncher controller PCB instructions. Paper feeding inside the puncher unit is performed by the delivery roller of the upstream connection machine and the inlet roller of the finisher.
  • Page 26: Configuration

    2. Technical Explanation Configuration The punch operation of this puncher unit is performed by two mechanical units: punch unit and punch slide unit. They are driven by the punch motor (M301) and punch shift motor (M302), respectively. Punch Motor (M301) Punch Motor Clock Punch Sensor (PS305)
  • Page 27: Horizontal Registration Control

    2. Technical Explanation Horizontal Registration Control The horizontal registration control during punching is performed by the movement of the punch slide unit in the front and rear directions according to the paper size. The punch slide unit is driven by the punch shift motor (M302). The home position is detected by the punch slide HP sensor (PS302).
  • Page 28 2. Technical Explanation 1. When the punch inlet sensor (PS301) detects paper fed from the upstream connection machine, the punch shift motor (M302) drives, and the punch slide unit starts moving to the rear. Punch Shift Motor (M302) Punch Slide Unit Punch Inlet Sensor (PS301) Paper...
  • Page 29 2. Technical Explanation 2.

  • Page 31 2. Technical Explanation 4. In precision priority mode, the paper moves by a given amount from where the punch inlet sensor (PS301) detects the trailing edge of the paper and switches back. The paper is fed to the position where it bumps against the paper stopper guide, and the punch motor (M301) drives to punch the paper.
  • Page 32 2. Technical Explanation 5. After punching, the paper is fed to the finisher feeding unit. At the same time, the punch slide unit moves to the home position. Punch Shift Motor (M302) Punch Slide Unit Paper Punch Slide HP Sensor (PS302) 6.
  • Page 33: Punch Operation

    2. Technical Explanation Punch Operation The Punching is an operation performed by a punch to make specific number of holes in paper. The punch is driven by the punch motor (M301) via a cam. Its home position is detected by the punch HP sensor 1 (PS303) and punch HP sensor 2 (PS304). During punching, the punch motor (M301) drives to turn the cam, causing the punch to move up and down to make holes in paper.

  • Page 38: Jam Detection

    2. Technical Explanation Jam Detection Outline The puncher unit is equipped with the following sensors to detect the jam at the punch operation. • Punch HP Sensor 1 (PS303) • Punch HP Sensor 2 (PS304) PS303 PS304 Jams The conditions for detecting whether a jam has occurred are stored in the puncher controller PCB in advance. A jam is determined by detection states of the sensors at the check timing.
  • Page 39: Power Supply

    2. Technical Explanation Power Supply Power Supply Route The 24V and 5V are supplied to the puncher controller PCB through the finisher controller PCB when the host machine is turned The 5V is converted into 3.3V by the regulator IC (IC5) on the puncher controller PCB. The 24V is used to drive the motors and the 5V is used to drive the sensors and the 3.3V is used to drive the logic.
