Position measurement for photoreceptor belt |
摘要 |
<p>A system is provided that improves the registration between color separation images in a color imaging process. The image data for one or more of the color separation images and the velocity of an image-carrying member (350) are controlled to remove or reduce registration offsets based on determined position and velocity of the image-carrying member. A position-determining sensor (352) is used to determine the process-direction position of the image-carrying member to provide real time motion information. A position-determining controller (248) determines the process-direction position of the image-carrying member by detecting a pattern of position-determining marks using the position-determining sensor and processing the detected data through averaging or correlation to eliminate detection errors to thereby improve the accuracy of the positional determination. <IMAGE></p> |
