Abstract: A decurler method and apparatus that compensates for ink contamination buildup on an indent roll of a decurler in aqueous ink jet products that can lead to paper wrinkle. A gap between the centers of the indent roll and a soft roll is increased to prevent sheet wrinkle by employing an algorithm that determines when the rolls are in contact and are first matching speed with each other and then treats this position as a home position.
