We have a Summa cutter repair site and I think we're the only Summa dealer that offers this service. There is a "depot assessment" that we offer where you can ship us your cutter for a full evaluation and we test everything including the various electronic boards, motors, belts, sensors, etc. and I am sure our guys can figure out what is going on with the error messages you are getting. We could probably figure everything out over the phone without having to ship us the cutter as well and that would be a less expensive option. I would give our tech team a call at 800-323-9766 and they can give you some different options. We used to own and operate Summa for over 20 years so we know what we're doing when it comes to Summa.
