         2. MECHANISM

   
   

   Transport mechanism

   Paper from the main machine passes through the horizontal registration sensor unit, and is transported to the punch unit and the entrance of the finisher.

   2	Punch unit

   
   

   Horizontal registration transport unit mechanism

   When the entrance sensor of the finisher detects the leading edge of the paper, the horizontal registration transport unit motor rotates to measure the horizontal registration of the paper. The horizontal registration sensor unit home position sensor detects the home position.

   PUNCH UNIT PU3040 (D716)

   Horizontal registration sensor unit mechanism

   

   The horizontal registration sensor unit has a horizontal registration sensor, which detects the horizontal registration (offset) of the paper relative to the punch unit position.

   2	Horizontal registration sensor unit motor

   Punch unit mechanism

   The punch unit moves according to information from the horizontal registration sensor, so that punch holes can be made in the correct positions. The punch unit is moved by the horizontal registration transport unit motor. The horizontal registration transport unit home position sensor detects the home position.

   Punch mechanism

   The punch unit motor rotates to move the links via gears. This moves the punch pin up and down. After punching, punch waste is collected in the punch hopper under the unit. The hopper has a punch hopper full sensor so that punch waste does not overflow. Because the punch motor is a DC motor, the motor shaft has an encoder, and there is a punch unit motor pulse sensor. The punch unit also has a mechanism for changing the punch positions according to the country/region of installation.

   PUNCH UNIT PU3040 (D716)

   Punching position changing mechanism

   The punch unit also has a mechanism for changing the punch positions according to the country/region of installation.

   • Japan: 2 holes

   • North America: 2/3 holes

   • Europe: 2/4 holes

   • Northern Europe: 4 holes

   The punching position sensor detects a change in the punching position.

1. holes

   The position where the 1st drive gear has not moved is the 2-hole home position. The 1st drive gear rotates clockwise/anti-clockwise, and only one link is moved, and this moves the necessary punch pins.

2. or 4 holes

The position where the 1st drive gear has rotated forward by 180° is the 3 or 4-hole home position. The 1st drive gear rotates clockwise/anti-clockwise, and the two links are moved, and these move the necessary punch pins.

      2. MECHANISM

Drive Mechanism

The paper exit roller and transport rollers 1-3 are driven by the side tray motor through gears and a timing belt.

Paper Transport Mechanism

The paper junction gate solenoid drives the paper junction gate. The paper junction gate changes the path of the paper transported from the main machine’s paper exit section to the upper or side paper exit tray.

Paper delivered to the upper paper exit tray is ejected by the paper exit roller, which is provided in the paper exit transport path. On the other hand, paper delivered to the side paper exit tray is transported by the transport roller, which is provided in the transport path. Two sensors detect paper jams.
