In checking out the Head Relay PCB - I may have nicked the very small flat ribbon cable on the left of the board. Is that the cable connected to the multi-sensor? I would need to remove it to test. Is this the correct part # -QK1-2758? I had a heck of a time reconnecting it when replacing the PCB. Probably because I did not remove the carriage itself. Has anyone done that before or do you always remove the carriage entirely when replacing the Head Relay PCB?
