ABSTRACT:
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.
