In addition to Alternaut's recommendations, double check the sharing settings on the Mac the scanner is attached to.

I just remembered something I ran into with a scanner after upgrading to OS X 10.8. After the upgrade the app I had been using to access the scanner apparently switched into 64 bit mode. Unfortunately the TWAIN drivers for my scanner are 32 bit only and I had to force the app to run in 32 bit mode in order to access the scanner. You should be able to in the Get Info pane for the app.
