How-To Steps
1. Remove the rear panel of the console.
2. Examine the wire inputs to connector J13 on the
control board. If any wires are loose, tighten the
screw terminals.
3. Using a continuity tester, measure the resistance
between terminals 1 and 2 when Feed Hold is
pressed and 3 and 4 when Cycle Start is pressed.
If there's continuity at the terminals on the
l
control board and the buttons still don't
work, examine the USB cable to the
control board.
If there's not continuity at the terminals
l
when the buttons are pressed, remove the
lower rear panel of the console and
examine the screw terminals on the rear
of the buttons themselves.
1. Remove the rear panel of the console.
2. Examine the USB cable going from the header
on the computer motherboard to connector J12
on the control board.
Shipping can sometime cause wire terminals to become
loose. Re-seating the wires will usually fix non-responsive
buttons.
If you have tested all terminals and the buttons still don't
have continuity when pressed, replace the buttons:
Feed Hold Button (PN 37363)
l
Cycle Start Button (PN 37362)
l
Verify that the power LED on the console control board
lights up when the console is turned on. If it doesn't light
up and you have confirmed the USB connection, replace
the control board (PN 39146).
