| 20100002032 | SCANNER, IMAGE FORMING APPARATUS, AND MOTOR CONTROL METHOD OF SCANNER AND IMAGE FORMING APPARATUS - A scanner, an image forming apparatus and a motor control method of the scanner and the image forming apparatus. The motor control method includes scanning a test image formed on a document, calculating an actual speed of a scan head moved by the motor using the scanned test image, calculating a matrix representing a relation between a driving signal to drive the motor and the calculated actual speed of the scan head, and renewing the driving signal using an inverse matrix to the calculated matrix to correct the actual speed of the scan head. | 01-07-2010 |
