摘要： An image forming apparatus and a method to control the same. The image forming apparatus variably outputs the PWM signal until the printing medium reaches the target position, accelerates the printing medium-feeding motor, and decelerates the printing medium-feeding motor in multi-stages. If the printing medium reaches the target position, the image forming apparatus decreases the PWM signal value to a predetermined value, maintains a current level, and stops the printing medium-feeding motor without rotating the printing medium-feeding motor in the reverse direction, such that the printing medium-feeding motor may instantaneously rotate in a reverse direction. As a result, the image forming apparatus can prevent the printing medium from stopping the feeding operation without reaching the printing medium to the target position due to the instantaneous reverse rotation of the printing medium-feeding motor, such that the printing medium can be maximally/correctly transferred to the target position.
