Win7 (64) image scanning question

I have an old Epson CX6600, an all-in-one inkjet printer, and I use it regularly for scanning in paperwork.

Epson Scan isn't supplied for this OS and printer, so at the moment I'm using the Windows Fax and Scan app that comes with Win7. It works reasonably well, but I'm trying to cut down the amount of interaction required to get a scan done. One of the steps involved is for me to tell it what area of the page I want to scan, but the odd thing is that Picasa uses the WIA system to auto-detect what's on the page and does it pretty well, as did the scanning wizard on XP (Picasa however requires more interactivity overall I think).

Is there a way that I can either get the Windows Fax and Scan app to auto-detect the area to scan, or perhaps another app I could use instead?

To do a single scan, I do the following:

Start 'Windows Fax and Scan'.
Click on 'New Scan' (I've already customised the app to do B&W 300dpi by default).
'Preview'.
Select area to scan.
'Scan'.
Right-click on file to rename it according to my preferences.
(start on a new scan)

I'm on a tight budget so I would prefer not to replace the printer with say something that has a sheet feeder (which I'm not sure would work that well because the paperwork has sometimes been folded or is dog-eared).

Any suggestions?

I am using a command line tool called CLScan (CLScan | Command Line Scanning | Downloads) and am perfectly happy about it.

It has a GUI also, but i prefer the command line mode.
