Patent ID: 8613440

Claim:
An automatic document feeding device comprising: a pick motor coupled with a pick assembly, said pick motor configured for driving said pick assembly, said pick assembly configured for pulling a media sheet from a beginning media stack one by one and feeding said media sheet into a main media path, said main media path configured for guiding said media sheet from said pick assembly to a first scanning region and from said first scanning region to an output tray, wherein said first scanning region comprises a first scanner positioned for scanning an image of a first side of said media sheet as it passes through said first scanning region, and wherein said pick motor is a direct current (DC) servo motor; a deskew motor coupled with a deskew assembly, said deskew motor configured for driving said deskew assembly, said deskew assembly configured for deskewing said media sheet and moving said media sheet from said pick assembly to a feed assembly, said deskew assembly moving independently of said pick assembly and said feed assembly, and wherein said deskew motor is a DC servo motor; a feed motor coupled with said feed assembly, said feed motor configured for driving said feed assembly, said feed assembly configured for feeding said media sheet towards said output tray from said deskew assembly along said main media path, and wherein said feed is a DC servo motor; and a sensor assembly coupled with said main media path and a computer, said sensor assembly comprising a plurality of sensors, each sensor of said sensor assembly coupled with at least one of said pick assembly, said deskew assembly, said feed assembly and said first scanner, said sensor assembly configured for sensing said media sheet moving along said main media path and based on said sensing, sending at least one signal to said computer, wherein based on said at least one signal, said computer sends an activation signal to at least one of said pick motor, said deskew motor, said feed motor and said first scanner.
