It seems like I have only two choices, either repair my scanner myself or
buy a new one. With repairing it myself I am not much confident. It seems
like the problem is kind of mechanical. Maybe dust somewhere on some
position sensors or anywhere else. With buying a new one (I would love to
buy Minolta DiMAGE Scan Elite 5400) it is difficult as it is little over my
budget in this moment. So if I can't repair it I need to make some extra
money. Maybe that is a good push for me to start selling some prints again.
