    • An image forming device capable of controlling an auto color registration (ACR) and a method of controlling an ACR. In the image forming device, a sensor detects preliminary test patterns by colors on a conveying belt; a color registration correction unit determines a present alignment state of the respective colors using data detected using colors by the sensor, and judges whether to perform a correction work of relative registration positions of the respective colors on the basis of the result of the determination; and a control unit forms actual test patterns on the conveying belt if it is judged that the correction work should be performed, and controls the sensor and the color registration correction unit to re-detect the data using colors and to perform the correction work.
    • 能够控制自动颜色配准(ACR)的图像形成装置和控制ACR的方法。 在图像形成装置中,传感器通过输送带上的颜色检测初步测试图案; 颜色对准校正​​单元使用由传感器使用颜色检测的数据来确定各种颜色的当前对准状态,并且基于确定结果判断是否执行各种颜色的相对登记位置的校正工作; 如果判断要进行校正工作,则控制单元在传送带上形成实际的测试图案,并且控制传感器和颜色对准校正​​单元使用颜色重新检测数据并执行校正工作。
