canon scanners and readiris

[Tim Grady]

I have a problem getting the scangear driver to pass on the info to  
the recognition part of readiris.  If I open up a .pdf file the  
recognition works, but if I scan a document with my 5600f nothing is  
recognized.  Does anyone know what options need to be set in the  
driver so that output from the scanner driver gets passed as input to  
readiris?
