Abstract:
A sheet registration and deskewing steering system with independent drives and steering comprising;a paper path for a sheet; a steerable drive mechanism for transporting the sheet along the paper path while imparting a lateral motion to the sheet as it is transported along the paper path; a sensing system for detecting the skew and lateral position of the sheet including a sensor located along the paper path; a first edge sensor, located along an edge of the paper path; and a second edge sensor located along the edge of the paper path in substantially the same lateral position as the first edge sensor; a pair of independently, separately driven first and second nips located subsequent to the steerable drive mechanism along the paper path; and a controller connected to the pair of independent and separately driven first and second nips and responsive to a signal from the second sensor for generating first and second drive signals for registering a sheet in the paper path.
