Nothing obviously wrong in the photo, but remember, the signal from the keyboard encoder you photographed to the distributor segments is a parallel bundle of wires.  If one of those wires is broken or not connected to the distributor segment, that also could be a source of trouble.

One thing to test, does the paper-tape reader transmit correctly?  If it does, then it's more likely you have a problem in your keyboard encoder.
