They are actually architectural drawing scanners that can be used to scan newspapers that are not torn or brittle from age. Flatbed scanners can scan very delicate newspapers, but the newspapers must be placed upside down on the glass plate of the scanner. These are the most common type of scanners for newspapers. Overhead scanners are used when the pages of a newspaper are so delicate that they are stored individually and cannot even be turned upside down.
