Thanks so much for the tips. Resetting the printing system is the only thing that worked, but only for a few scans. When I turned off the scanner after I was done and then tried to use it again a few days later, my computer did not recognize that the scanner was plugged in. Tried restarting, using a different USB plug, a different USB port and nothing works. I tried using Image Capture, Preview and even Photoshop, none seem to recognize that the scanner is plugged in. Tried upgrading to Mavericks v.10.9.3 to see if that would work, but nothing.
Is it time to throw this scanner away and get another one? I use it to scan negatives, transparencies and art but don't have a huge budget so I was hoping to get this to work.
