it says OCR is done by software. this means it is likely able to take a 
traditional 'picture' of the document. this part could perhaps work under 
sane, if you have enough programming docs, or the ability to reverse 
engineer the windows driver.

all the other things it does (reading micr, etc) and the actual OCR 
process cannot be done via sane, but perhaps by an external program (which 
you would likely have to write yourself)

first step is likely to get programming docs from manufacturer, or a dump 
of windows driver activity using benoit's usb sniffer, and try to write an 
external program using libUsb which mimics the windows driver.
