I have a scanner with the scan bar at the tail end. When I plug it in, the scan bar moves to the front, flashes when going back 1 inch, and then returns to the previous position (tail end). I don't have a warranty on this one and would appreciate any hints. Thanks.
i have tried everything and found a temporary fix, when the bar gets to the bottom I mash the auto scan button many times and it fixes the bar and the scanner goes back to normal but it goes back to be normal the next time I try to use it. now this fix has stopped working, this is planned obsolescence by canon. So we have to buy new scanners every few months. This is a firmware issue. That I am sure of. they have no way to rest its firmware.
