IMAGE FORMING APPARATUS AND AUTOMATIC COLOR ALIGNMENT METHOD THEREOF CAPABLE OF INCREASING THE ACCURACY OF ACR(AUTOMATIC COLOR REGISTRATION)

摘要

PURPOSE: An image forming apparatus and automatic color alignment method thereof are provided to minimize the interference of a jitter, slip, and a transfer belt and to increase the reliability of ACR.;CONSTITUTION: An image forming apparatus includes a transfer unit(110), an image forming unit, a sensor, and a controller. The transfer unit includes a conveyor belt. The sensor includes an OPC(Organized Photo Conductor) speed sensor, which senses a first pattern, and an OPC synchronization sensor which detects image carriers. The controller controls the image carriers according to the sensing result of the OPC synchronization sensor. The controller performs the driving rate of the image carriers based on a first pattern.;COPYRIGHT KIPO 2011
