Abstract:
1. An image printing apparatus, comprising: at least one pair of feeding rollers disposed in pairs in a vertical direction at a predetermined interval to feed a sheet of recording paper picked up by a pickup roller along a sheet feeding path; a document position sensor to detect whether the sheet picked up by the pickup roller reaches a set reference position; a storage unit to store information about the position of the sheet at which a white line would be produced, wherein the storage unit stores the information regarding sheet size; a printing part to print an image as the sheet is fed into a printing area; and a control unit to control a feeding rate of the feeding rollers using the information stored in the storage unit about the white line producing position of the sheet, wherein the sheet is fed at an initially set feeding rate starting when the sheet is detected to have reached the set reference position by the document position sensor until the white line would be produced, and the sheet is fed at a different feeding rate less than the initially set feeding rate starting from the time when the white line would be produced on the sheet.
