FINDINGS: The deeds settings worked with me at first under Windows 7 is not. But with the help of EPSON support was soon clear that the so-called services settings in Windows 7 the evil were. After correction (Windows Image Acquisition WIA and all dependencies !!) everything was fine! Recommendation: highly recommended Price: Goods & Returns = top position in November 2010 in comparison
