I'm having an issue with an Epson Perfection 2450 scanner that worked fine with Lion until recently. Now I cannot get the scanner to work and there are odd things going on.
I've reset my printer system in system prefs and unplugged/restarted the scanner and restarted my mac several times. The scanner either doesn't show up in Preview or shows up multiple times. Last time I cleared the printers I had 5 instances of the scanner to choose to add; none of them worked. I keep getting either "scanner not available" or "failed to open a scanning session" error messages.
