I switched it to EPP, removed the printer, and voila! I have a scan.

However, I only got a small scan (not full size of page), and the 
background is red. I'm trying to scan text to do OCR.

I tried a full page of text and the background isn't red, but the text 
is not high enough resolution at all.

I'll look into getting the it work with Xsane (have to get user to 
access scanner yet).

Any tips?
