Just guessing here.
Try uninstalling the printer completely then shutting down the system and disconnecting the printer.
Restart the computer, and re-install all of the Epson setup files. When done, close down, re-connect the printer, and see if that works.
My laptop crashed & have gotten most everything restored, but I recently moved & haven't been able to locate the CD for my Epson printer/scanner to reload the driver. I can use the printer & copier functions, but not the scanner! Have tried unsuccessfully to download the driver (even getting instructions from Epson which told me to do what I'd already done).
I keep getting a message that says it can't copy all the files. Epson said I didn't have enough memory. I emptied my TEMP files & recycle bin. Still no good. My husband tried it on his computer - same thing. (Mozilla, IE - same results)
