Canon IRC 3200 ADF isn't recognized

[samsamantha]

Right now I am trying to help my father with a 3200 ADF that he has tried to connect to the copier. He has two ADF's, and neither of them are doing a thing when connected. The only lights that are lit are the two red lights under the middle panel of the ADF. We will have the bottom one lit, he flips the dipswitch, pushes the black reset and then the top red starts to blink. There is nothing else at all that happens.
