Abstract
A copy media registration module for positioning paper in a feed path is disclosed. More specifically, the present invention is directed to a method and apparatus for detecting pre-drilled holes in copy media. A sensor detects the presence and absence of copy media in the feed path. Once a transition from paper to no-paper, or from no-paper to paper occurs, subsequent signals from the sensor are ignored for a designated period of time. At the leading edge of the sheet, this designated time period is chosen such that any possible holes will have moved past the sensor. At the trailing edge of the sheet, the designated time period is chosen based upon the maximum size of any holes that may be present.
