Before I put this in the recycle bin I thought maybe someone might think it worthwhile to attempt a fix. The problem I wont try to describe and is of unknown origin. See example attached at 400% crop. This problem was progressive, starting occasionally and now pervasive. At first I thought it was software related and would update Vuescan to latest version and that seemed to work. Now, even when going back to vuescan versions when it was fine doesn't help. Others have sworn that this is fixed with Minolta scanning software, while others say it is a hardware issue and the unit requires all the gear lubricant to be removed and cleaned. I have moved on from all this. $50 + shipping USA. Free if anyone wants to pick up in NYC/Brooklyn.
