I have just installed the Epson CX3650 all in one device on my new Windows 7 laptop. During the install process it said that the device was not compatible. It allowed me to install it anyway and the printer part of the device works. When I try to scan a document, however, it doesn't work and I get the error message that the scanner is not ready or another applcation is using it. Any help would be greatly appreciated. Many thanks
