I just installed a new HP ScanJet 3200C and was scanning my first image when the power went off. When the power cam back on, I restarted my computer and tried to start scanning again. When I tried to run the scanning program I got a message: "Can not find scanner. You may have a scanner hooked up to your computer, but the program can't find it." What do I do??? I've tried everything I can think of. I've checked and rechecked the connections. From what I can tell, I have everything hooked up right. Can anyone help me?
