Punch Unit Position Correction
These operations (skew correction before punching, and punch unit position correction) increase the ac-
curacy of the punch alignment.

:
The trailing edge of the sheet passes the finisher entrance sensor [A].
The paper position slide unit [B] moves the paper position sensor [C] forward to the edge of the paper.
The paper position sensor detects the position of the paper edge and sends this information to the punch
unit board. The machine uses the detected position of the paper edge to calculate the correct position for
punching.
The upper transport motor switches on and rotates the feed rollers [D] the prescribed distance to position
the paper under the punch unit.
·
:
Using the result of the position calculation, the punch unit control board moves the punch unit [E] to the
adjusted punch position.
The paper position slide unit and its paper sensor, move back to the paper position slide home position
sensor [F], and the punch unit fires the punches to make the holes.

:
The feed rollers [G] feed the punched paper out of the punch unit and into the paper path.
