I have installed the most recent Epson driver more than once after walking through w/Espon support all the files that needed to be deleted to trash the app.
No special processing while scanning. Just using the full auto mode and also the professional mode. Also tried saving in different formats, since starting this thread, and it still quits the moment the scan is finished.
Using Preview actually brings in the Image Capture app. Although it does not quit, I am not happy with the scan results. Things turn kind of flat. I do like the results of Epson scan.app for my purpose.
Have plugged the usb cable directly to the computer.
I think that it is an issue with OS 10.6.8 and Epson software compatibility. I believe that Epson should update the drivers, but aren't likely to do so.
So I guess I have to decide whether I want to put up with restarting each time or use Preview/Image Capture and tweek each image after the scan.
Thanks everyone for responding. I appreciate your input.
