Abstract
A method of compensating a sheet feeding error in an ink-jet printer includes printing a test pattern on the sheet; scanning the printed test pattern using the image sensor and measuring a distance Wbetween a starting point Xand an ending point Xof the test pattern; driving the feeding roller and moving the sheet to a set distance Hso that the set distance His shorter than a length of the test pattern in a sheet feeding direction; scanning the test pattern using the image sensor and measuring a distance Wbetween a starting point Xand an ending point Xof the test pattern; calculating a distance H, along which the sheet is actually fed, from a difference between the distances Wand W; calculating a feeding error E of the sheet from a difference between the feeding distance H and the set distance H; and compensating for the sheet feeding error E at the set distance H.
