We have for sale a scan gear motor for a Roland XC540. Does fit other models. Good working order. We replaced ours with a new one only to find this wasn’t causing the error we had ! £50 post included.
Also have a Correx tensioner gauge. 1000 gramm. Bought hen we installed a new belt on our Roland to set the correct belt tension. Again in great condition and perfect working order. Ideal if you do your own repairs. Again £50 post included
