It is like Epson saying the V600 scanner has a max resolution of 12,800 dpi but the optical resolution is only 9,600. Both numbers are totally bogus in the real world, I would speculate by somewhere around a factor of 8 from experience.
Well, I would have to say your Noritsu was misfocused or otherwise out of alignment because mine delivers spectacular results that are very close to my Imacon. I have to say that mine was focused and aligned by an expert before he sold it to me and I do have the hard to find focusing tools to keep it in perfect order. I suspect some of these machines have not been so well attended to.
