    摘要: An image processing apparatus includes a corona device with a charging grid for charging a photoreceptor to voltage levels, an exposure device for projecting an image onto the photoreceptor, a developer for applying toner to the photoreceptor, and a sensor for providing a signal in relation to current flow between the photoreceptor and the developer. An exposure device control adjusts the exposure device by setting the exposure device to an intensity level of approximately 50%. A photodetector sensor provides signals to the exposure device control in relation to the 50% intensity level in response to developing the predetermined test patches on the photoreceptor and the exposure device control adjusts the exposure device in response to the photodetector sensor signals without the use of test patches to an intensity level of approximately 100%.
