  The Snapscan backend currently treats the 1236S as if it is a 30bit
  scanner. The Afga site says its a 36bit scanner. In that case the error may
  be a simple one. In snapscan.c look for the section that sets the colour
  depth for the scanner (look for pd->depths = depths12). In that sections
  add the line "case SNAPSCAN1236S:" above the existing line "case
  PRISA620S:" and see what happens.

  Remember - this is just a guess!
