1. In an imaging apparatus having a media input tray having a pick mechanism and a tray media sensor positioned downstream of a pick point in the media input tray, a media path for transporting a media sheet from the media input tray through an image transfer nip to receive a toned image from a print engine, and at least one pair of opposed feed rolls and a path media sensor positioned on the media path between the transfer nip and the media input tray, a method for feeding a plurality of media sheets comprising:
picking a media sheet N from the media input tray using the pick mechanism; waiting for a predetermined pick delay time period to elapse in which a trailing edge of media sheet N clears the pick point but has not cleared the tray media sensor then picking a media sheet N+1; and determining whether the trailing edge of the media sheet N is detected by the tray media sensor, and, when the trailing edge of the media sheet N is detected, then continuing feeding the media sheet N to the transfer nip using the at least one pair of opposed feed rolls and waiting for the predetermined pick delay time for media sheet N+1 to elapse before beginning picking a media sheet N+2, and, when the trailing edge of the media sheet N is not detected by the tray media sensor, then:
determining whether or not the trailing edge of media sheet N is detected at the path media sensor within a predetermined transit time period, and, when it is determined that the trailing edge of media sheet N has been detected by the path media sensor within the predetermined transit time period, continuing feeding of media sheet N and media sheet N+1 to the transfer nip and the picking of media sheet N+2, and, when it is determined that the trailing edge of media sheet N has not been detected by the path media sensor within the predetermined transit time period, declaring a misfeed of media sheet N. |
