I don't think this has been posted so I thought I'd give users of these models a heads up.If you use the canned profile supplied for Epson papers, As of Nov 02 Epson has released V 6.62 drivers which finally include some of the newer papers that have not been included in the canned profiles drop down list till now.
They also have very abbreviated profile names. When doing ICC settings from the windows ICC color folder you have to scroll down the alphabetical list to find them as they start with SP7900 9900 instead of the older Pro9900_7900 names.
