c. As a double check, hold the entire Paper Guide assembly up so that you
can visually inspect the alignment between the sheet metal surface and the
metal surface of the Aligner. The green drive belt should appear to be even
or parallel, and just floating above the surface of the sheet metal.
3. To install the Paper Guide assembly into the Advanced Punch:
a. As you slide the Paper Guide assembly into place,
– Hook up the Sensor Harness to the Sensor on the back.
– Lift it up slightly to clear the lower Transition Paper Guide.
– Be sure to clear the Sensor Bracket at the top left.
– Be sure that the Flex Coupling Shaft is sticking out of the rear of the GP-501
Punch properly.
b. Visually check all around the mounting area of the Paper Guide assembly
and that the Sensor Harness is properly connected.
c. Loosely secure it in place with 3 screws on the left and 3 on the right.
d. Loosely install the 2 top screws.
e. Once all 8 mounting screws have been properly started you have good
alignment. You may now go back and tighten the screws until they are snug.
