Abstract

Time between recording print on one media sheet and a subsequent media sheet is substantially reduced by ejecting, picking and loading within a single transmission state. In a continuous feed mode multi-sheet job, individual media sheets are continuously picked and loaded. The leading edge of one media sheet is substantially adjacent to the trailing edge of the prior media sheet. A media support plate is maintained in a raised position during the entire continuous feed cycle. The support plate biases a paper stack into communication with a pick roller. As the trailing edge of one media sheet exits the media stack, the leading edge of the next media sheet is already in position for engagement with the pick roller. Upon completion of print recording, a media sheet is ejected into an output tray by accelerating the media sheet. Such acceleration is achieved while remaining in the single transmission state.
