We carry many replacement parts for the SAM4s SPS-340 cash register. Even a very durable cash register from time to time may require a replacement part, if it does we have you covered.
Make certain you unplug your cash register before making any repairs and as always back up your program before starting. If you are not sure about making your own repairs contact us to discuss your options for repair. We also can also help you with programming and reporting issues via the phone.
