Can you see the sensor or know where it is? If it's optical, I wonder if there could be lint or something like that on it. It must be something that picks up either the position of the little rectangular needle hole piece in the plate, some aspect of the mechanism on the back of the plate, or the position of the lever that operates the plate.
I can't look at my 7700 and see what it used (and based on experience, I don't believe the 7700 has the same sensor).
