    GR 3750 T3 call service

    Got a call for a Risograph GR 3750 T3 call for service in display. Anybody know what this problem is? 20 plus year old machine. Also does anyone know of a source for refurbished duplicators.

    Does it make a popping sound 4 or 5 times before it gives the T-3? If so there is a crack in the clamp plate motor assembly. With it out of the machine you can bend it back down into position and put a bead of solder weld in the angled corner and it will be better than new.

    Or look at http://www.copytechnet.com/forums/di...-t3-error.html
