My Epson Perfection 1650 is giving weird results when I scan B&W photos from a book (printed on plain paper, not glossy coated). No matter what the settings, shadow lines appear when I zoom in on the resulting image. The effect is somewhat as if light is passing through a venetian blind onto the subject.
My ancient HP ScanJet IIcx produces great results on the same photos. I worry only that someday the software will no longer work.
The Epson is highly rated by some reviewers. What am I doing wrong?
