Abstract
A sheet feeder is provided comprising at least two drives that drive a sheet of material along a paper path and at least two sensors that detect a lateral side of the sheet of material. A controller is connected to the two sensors and at least one of the drives. The controller varies the drive velocity of at least one of the drives to shift the lateral position of the sheet of material in a predetermined direction until one of the sensors detects the lateral side and then varies the velocity difference of the two drives to eliminate the skew of the sheet.
