Flatbed Scanners
— Facedown scanning places stress on bindings
— Books must be lifted to change pages
— Images are distorted near the page binding

Overhead Scanners
— Books must be fully opened to 180 degrees
— Center of book creeps as pages are turned creating margin crawl
— Images suffer from curved text lines

Copystand with Cradle
— Books are partially opened on a v-shaped cradle and gently sandwiched under platen
— Cradle and platen keep pages flat and eliminate margin crawl
—Two cameras simultaneously capture sharp, curvature-free images
