Part 4 of Ralph Griswold's series on making digital facsimiles of documents, covering how to scan printed pages. It explains resolution (ppi) and bit depth, gives minimum, recommended and maximum scanner settings for text, line art, grayscale pictures and color pictures, and discusses descreening of halftones. It also covers physical handling on flatbed scanners (flattening bound books, supporting large books), pages with mixed print types, selecting scan areas, scanning two pages at once, and stitching oversize pages.
