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.

[ What is claimed is:] [1.] A paper transporting system for an ink-jet printer having a print head, said system comprising:paper feeder means for feeding paper into said printer and for transporting said paper through said printer;paper sensor means for sensing a presence of said paper as fed by said paper feeder means, and for generating a sensing signal;position value designator means for storing at least one designated position value in accordance with a paper transporting distance;arithmetic controller means responsive to said sensing signal for counting steps of said paper feeder means and for comparing a count value of said paper feeder means to said at least one designated position value; andcontroller means connected to said print head and responsive to said arithmetic controller means for controlling said print head to move back and forth so as to level-guide said paper with respect to a surface of said print head that faces said paper, thereby preventing said paper from becoming jammed and folded;wherein said at least one designated position value comprises a first designated position value indicating a position at which said print head needs to move back and forth without printing to level-guide said paper.
