You have what is called a CIS (contact image sensor). Similar to a CCD. If you do a search for "line scan ccd arduino" you will find someone who found a datasheet to the controler chip and then figured out what pin does what. They figured out how to connect it to an overclocked arduino and use it as a shadow based touchscreen controler. If you still have the orignal driver boards you may be able to do the same thing. I am trying to do a simalar project but just want to remove the throw a error disable the entire device multifunction canon printer scanner combo controller out of the equation.

Sam T Nice, I will have to dig that up that information. Would be fun to build my own handheld scanner rather than buy one.
