Abstract:
A sheet processing apparatus and methods of utilizing the same. The sheet processing apparatus includes a punch mechanism disposed along a media path at a punch point at which a hole is to be punched through a punch location on a media sheet advancing along the media path. The punch mechanism includes a rotatable punch arm having a punch head, and a punch motor for rotating the punch arm. As the punch location on the advancing media sheet approaches the punch point, speed of the punch motor is controlled to adjust a rotational speed of the punch arm based on feedback signals associated with each of the punch motor and a media path motor used to advance the media sheet such that the punch head arrives at the punch point at substantially the same time as when the punch location on the media sheet arrives at the punch point.
