I got a TSP6000 with a similar problem but either pivot not home, no pivot function, i replace pot 5, calibrate but no sense in both sides, i checked arnes and solenoids but the problem persist, both pivot cyliners goes in the same direction, when press traverse and pivot buttons at the same time traverse run fast but no pivot function, what can I do ? Sometimes when i press those buttons at the same time appears 765 and 769 codes
