Last word on this...I decided to email Epson support instead of calling like I did last time. In my email I covered what happened with my previous tech trip. An advanced tech guy emailed me wanting to remote to my SP3 (don't know why the others didn't suggest this). He downloaded a tool called Epson Registry Cleaner and clicked on it. It took all of 5 seconds and was done. He then told me to click on the Epson scanner icon, which I did. It opened as always & I then clicked on the scan button...lo and behold, it scanned perfectly. He told me if things ever get glitched again to just run that little tool and all should be well. He also said that having an SP3 makes no difference one way or the other. That's what you all said, and what I thought, but I find it amazing how one tech person can handle something easily and the next one can't and yet they both work for the same company. I've run into this before, though, so I shouldn't be surprised. Anyway, Epson GT-1500 scanner is working beautifully again!
