ABSTRACT:
A pivotal, bi-directional decurler that changes sheet bending direction from an away from image to a toward image direction includes a decurler support structure that is mounted for bi-directional movement by a cam mechanism. A belt member is entrained around two support rollers that are supported by the decurler support structure with an unsupported span between the rollers. A pinch roll is adapted to form a nip with the unsupported span of the belt to provide away from image bending of copy sheets when the cam mechanism is rotated into a first position. An elastomer coated rotating shaft positioned downstream of the away from image nip cooperates with a bending baffle when the cam mechanism is rotated into a second position to provide toward image bending of copy sheets.
