PUNCH POSITION ADJUSTMENT

2. DETAILS

The punch unit punches holes in printed sheets, one by one. The punch unit is
provided with a new punch mechanism to improve the accuracy of punching.
NOTE: The illustrations below show the unit for Europe for 2/4 hole punching. The
North American unit has five holes for 2/3 hole punching.

2.1.1 PUNCH DRIVE MECHANISM

The punch motor [A] drives the punch mechanism. At the correct time after the
trailing edge of the paper passes the finisher entrance sensor [B], the punch motor
turns on and the paper stops. The punch clutch [C] turns and drives the punch
heads [D].
The punch HP sensor [E] detects the home position for the actuator. The punch
unit switches off when the cut-out in the punch shaft disk [F] enters the punch HP
sensor.
NOTE: SP6113 (Punch Hole Adjustment) adjusts the punch hole position in the
sub scan direction for two holes (001 2-Hole) or for three holes (002 3-
Hole). Use the spacers provided with the punch unit to adjust the position
of the punch in the main scan direction. For details, refer to the installation
of the punch unit in section "1. Installation").
