In a transporting system and method for an ink-jet printer, a paper is transported to an ejecting area without being jammed or folded by moving a print head back and forth to level-guide the transported paper with respect to the lower surface of the print head when the paper is at a designated position, while continuously transporting the paper toward the ejecting area. The system and method provide for a paper sensor which generates a sensing signal when the paper enters the paper feeding area, a position value designator which stores first and second designated position values, and an arithmetic controller which counts the number of paper feed driving steps, compares the count value to the designated position values, and determines based on the latter comparison when the paper is at a point between the feed area and the eject area at which it needs to be supported by movement of the print head back and forth.
A media discharging device for an ink-jet printer includes a rubber roller and star roller. A pair of paper guides are arranged on both sides, with respect to its rotary shaft of, the star roller, opposing each other and close to the star roller. Each paper guide has a slant which is inclined gradually upward in the paper discharge direction. This slant is positioned offset with respect to the path of movement of the projections on the star roller towards the paper discharge side, so as to prevent the rear edge of the recording paper from dropping into the recessed portions of the star roller.
In a printing apparatus a printing medium is fed such that before a paper sensor detects a trailing edge of a preceding printing medium, a paper feeding roller begins the feeding of a succeeding printing medium, and after the paper sensor detects the trailing edge of the preceding printing medium, a leading edge of the succeeding printing medium arrives at the location of the paper sensor. Thus, the feeding of printing paper is performed rapidly and consequently the printing apparatus can perform recording rapidly.

The present invention is embodied in a low-profile and narrow-width printer that has two rollers, a pick roller and a feed roller, and two roller motors. Each one of the two roller motors is used to drive one of the two rollers. As a result, a short gear train can be used to allow a longer paper path for enabling a low height printer. Also, a print media can be picked up from the input tray while another print media is being printed upon by an ink jet printhead or printhead. Thus, throughput of the printer can be enhanced when the printer is printing a multi-page document. Further, the printer straightens out print media that are skewed when picked up by the pick roller. Finally, the printer is able to locate a paper jam by using two sensors, one by the pick roller and the other by the feed roller.
A media eject system for a printer having an output tray includes an edge wing for supporting an edge of media exiting the printer, the edge wing movable between support and non-support positions. A kicker engages a trailing edge of media and moves the media into the tray. The kicker is movable between a retracted position and an extended position and operable to move the media into the tray by movement of the kicker from the retracted position to the extended position. A controller determines a print condition including at least one of a media type and a print format, and adjusts a position of the wing dependent upon the print condition.
