Eric - First, thank you for such a quick response!
Yes I've tried your suggestions already. When I open Image Capture it reads "No Camera or Scanner Selected". There is no way to load a scanner. :\
When I open System Preferences/Print&Scan, click on the Epson, click on Scan, click on Open Scanner... the little scan "icon" in the upper right hand corner isn't lit up.
In Preview, when I click on "Import from Epson XP-800 Series", the screen is blank. Eventually an error reads "An error occurred while communication with scanner.
Nor can I scan from the Epson into my Mac.
I'm not the only one. I found one other person online with the same problem. My sister and I also have the same printer and she's the one who alerted me of the problem. When I tried to fix her printer... I couldn't do. So I checked mine... same problem as her's.
This problem started after one of the last 2 upgrades, because we were scanning not that long ago.
As for the link you provided... been there, done that. I already uploaded their most recent driver... and nothing changed.
Please help we are dead in the water on some work projects!!!
With sincere appreciation,
