Document scanners
Scanners are relatively simple devices, these days often incorporated with a printer in an "all-in-one". In this page we examine how thy work and the hardware or software problems that can occur.
Summary
Unlike a camera, a flat bed document scanner records a single row of pixels at a time using an illumination source and a row of sensors mounted on a bar which is drawn across the document by mechanical means. Problems can arise with the mechanics, the electronics or the software.
