Punch Unit Position Correction
These operations (skew correction before punching, and punch unit position
correction) increase the accuracy 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.
