摘要： An apparatus and method are provided for reducing a printing position error, in which the method includes the steps of (a) driving an encoder wheel as many times as a predetermined number of forward counts at a predetermined initial acceleration, thereby making the edge of a printing paper become separated from a sensing unit and conveyed in a forward direction, (b) driving the encoder wheel at the predetermined initial acceleration and conveying the printing paper in a backward direction, (c) calculating a difference value between the number of backward counts of the encoder wheel from a start time of the backward driving to a point when the sensing unit detects the edge of the printing paper and the number of forward counts, and (d) repeating the steps (a) through (c) for a designated number of times while varying the predetermined initial acceleration, and setting an initial acceleration corresponding to a smallest value among the difference values as the initial acceleration for driving the encoder wheel. Therefore, in the case of separately printing data on one printing paper several times, the resolution of a printed image can be improved by reducing the printing position error.

摘要： A method and apparatus are provided for measuring the optical density of an image printed on a medium in an image forming apparatus. The method includes the steps of reading reference information from a memory, measuring the amount of light reflected from a medium on which a target image is printed by applying light to the medium, and calculating the optical density of the target image using the reference information and the measured amount of light reflected from the medium. Accordingly, it is possible to precisely measure the optical density of an image printed on the medium without the aid of an additional optical density measurement device and easily reduce differences or variations in the quality of printing between image forming apparatuses.
