Abstract: An image forming apparatus for generating a stable horizontal sync signal and a horizontal sync signal generating method are provided. The image forming apparatus includes a switching unit to switch on an electric current according to a video signal, a light output unit to output an optical power corresponding to the electric current, which is switched on by the switching unit, an optical power controller to control an intensity of the electric current switched on by the switching unit, and a printer engine unit to output an optical power control voltage to amplify the intensity of the switched-on electric current during a horizontal sync signal generation period included in the video signal. Accordingly, a stable horizontal sync signal is generated, and the deterioration of the quality of a print job is prevented.

Abstract: Disclosed are a scanner and an image forming apparatus employing the same. The scanner may produce bidirectional scanning of light by oscillating a deflecting mirror about a first axis substantially parallel to the mirror surface, and may compensate for skewing of the scan lines by rotating the mirror about a second axis that is substantially perpendicular to the first axis so as to allow the light to be scanned at an angle.

Abstract: A method of controlling a revolution speed of a spindle motor in an optical disk drive. Target RPMs and actual PWM signal values for maintaining the target RPMs are calculated according to recording linear velocities of an optical disk, and stored in a memory. The spindle motor is controlled by a PWM signal value greater than an actual PWM signal value for maintaining a desired target RPM, until an RPM of the spindle motor reaches the target RPM. Further, the spindle motor is controlled by the actual PWM signal value for maintaining the target RPM, when the RPM of the spindle motor reaches the target RPM.
