Newspaper scanners come in three flavors: 1) feedthrough scanners; 2) flatbed scanners; and 3: overhead scanners. Feedthrough scanners have a wide throat that the paper is fed through. 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. The most common assumption/misconception about scanners of any kind is that they always 'read' the text and convert it into editable form. This function is in fact a software add-on. The scanners themselves simply convert objects into digital images that can be viewed and read as is or further processed by Optical Character Recognition (OCR) software and text or PDF files output.
Newspaper scanners are used to digitize physical copies of newspapers into electronic formats. This process involves scanning each page of the newspaper to create digital images that can be stored, archived, and accessed electronically. Once scanned, the digital copies can be easily searched, shared, and preserved for future reference.
