PRINTER GPIO BOARD

TM
SX 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.
