Hole Punch Adjustment - Lexmark C920 Service Manual

Hole punch adjustment

You can adjust the hole punch alignment by approximately 4 mm (3/16 in.). This adjustment is useful when you
want to center the punched holes onto the paper or if you hole punch a printed job on different finishers.
Note: The following procedures are used for both three- and four-hole punch finishers.
1.
Verify the alignment of the printer and finisher is correct.
•
If the alignment is not correct, go to
hole punch another sheet of paper, and see if an adjustment is needed.
•
If an adjustment is needed, continue with step 2.
2.
Using a sheet of paper previously punched from the finisher, fold the paper so the bottom punched hole is
aligned with the top punched hole.
3.
Determine if the edge of the bottom of the page is below or above the top edge of the page.
4.
Loosen the guide rail thumbscrews.
Note: Do not move the adjustment knobs more than three complete turns from their starting position.
Adjustments greater than three turns may cause paper jams.
5.
Rotate both adjustment knobs the same amount to raise or lower the side of the finisher.
•
A half turn of the knob moves the position of the hole approximately one third to one half the distance
of the punched hole.
•
To move the bottom of the paper down, rotate the knobs clockwise.
•
To move the bottom of the paper up, rotate the knobs counterclockwise one quarter turn.
6.
Tighten the guide rail thumbscrews.
7.
Print and punch another piece of paper.
8.
Repeat steps 2 and 3. If the holes are not aligned, repeat steps 3 through 8.
