ELECTRICAL COMPONENTS
WARNING
This procedure deals with handling parts
susceptible to damage from electrostatic
discharge (ESD). Use static control precautions
while servicing this equipment.
PRINTER GPIO BOARD
The Printer GPIO Board is only present in Sharp
SX
TM
Baggers that are equipped with a printer. It is
used for communications between the PLC and the
Datamax Printer. A defective GPIO board will
typically result in the printer running continuously
without the bagger running. A non-functioning
printer is usually caused by faulty relays. Refer to
the Grey and Red Relay sections to troubleshoot a
non responsive printer.
There are no testing procedures for the Printer
GPIO Board.
There are no adjustments necessary on the GPIO
Board.
1. Unplug the GPIO cable from the GPIO Board
(Figure 3-115).
2. Remove the two screws holding the GPIO
Board to the Card Carriage.
3. Pull the board straight out towards you and set
aside.
4. Line up new board with the card track inside
the Card Carriage (Figure 3-116).
5. Slide new board all the way into Carriage.
Resistance will increase in the last inch as the
board slides into the connector.
6. Screw new GPIO Board to Card Carriage.
7. Reattach GPIO cable.
