I tried to scan a picture, and got a message that there was an error in communicating with the scanning device, and that I should make sure that it is connected properly and try again. The power is on, because the little light on the cover is on. I checked both ends of the USB cable, and they appear to be firmly attached, but I still get the warning. I even tried restarting the computer. Can anyone help me? Thanks.
