Theory of Operation.
Possibly with C-4521 and/or C-4522 error codes.
CAUSE: ICP17 isOPEN on the Printer Control Board. The wiring between the printer control board and the hardware counters may be pinched. If the wire is
shorted to ground, ICP17 on the printer control board will open, resulting in the error code. If the wire is broken internally without shorting, the machine will
function but the counter will not increment.
SOLUTION:Check the wiring between the PRCB and the Total Counter. There might be a short to ground close to the Total Counter. After the short is found
and repaired, replace the PRCB (p/n A03U R759 00).
If the wiring is not damaged, reposition it so that it is secured in the plastic hooks behind the counters. This will keep the wiring from being pinched when the
cover is removed and reinstalled.
It is recommended that all machines be inspected at setup or the next service call to prevent future incidents.
