Sheetfed scanners: what are they and how do they work?

Sheet-fed scanners typically include a stand that allows the document to be scanned to be fed into the scanning position along a horizontal path or an inclined path. The scanner includes a housing, a sheet feeder, a scanning module, an actuator, and a calibration sheet.
