I just got a new scanner for Xmas. I installed the software and unplugged the printer to the back of my computer to attach the scanner. The scanner has a port for the printer cable which I connected. I tried to scan a pic and it says to check my cables there is a problem with them. I checked them. I unplugged them, reattached them. I don't know what else to do. Am I doing something wrong here? Can you help me get this thing working?? I have my printer on when I am trying to scan a pic, I thought maybe that was the problem. Still it is telling me to check my cables??
