ABSTRACT:
The present invention comprises an apparatus and method for transporting print media with wet ink out of a printer without smearing the ink or requiring the user to adjust the margins of the document to avoid the smearing of the ink. The apparatus comprises a platen for holding the print media prior to ejection from the printer, an ejection bar having flexible, resilient fingers for catching the bottom of the print media when flexed and then kicking the paper out of the printer. The ejection bar is actuated by an eccentric cam drive to move it away from the print media when the fingers are traveling toward the bottom edge of the print media, then moving it toward the paper bottom edge to flex the fingers and then upward to eject the paper out of the printer. The upward movement also causes the fingers to spring to an unflexed configuration, thereby kicking the paper out of the printer.
