ABSTRACT:
A method and apparatus for controlling registration sensors are provided, in which a transfer unit transfers an electrostatic latent image onto a printing medium, at least one registration sensor senses image alignment errors by irradiating light to the transfer unit to sense reflected light, a sensor data storage unit stores characteristics data of the respective registration sensors, and a sensor control unit controls the registration sensors based on the characteristics data of the respective registration sensors, wherein the registration sensors are placed into the transfer unit. Accordingly, time for performing an algorithm of color registration can be reduced, and registration can be achieved correctly in a short time, irrespective of a set frame of the image forming apparatus.
