<p><P>PROBLEM TO BE SOLVED: To provide a control method for a line head, whereby exposure displacement is corrected to improve image quality. <P>SOLUTION: The image processing section 27 of a print controller 21 image-processes image data corresponding to an amount of one page and transmits the image-processed data to a page memory control section (C plane)23. In the page memory control section 23, the image-processed data are separated according to each line of light emitting elements, and stored in page memories 24 to 26 corresponding to light emitting element group lines A to C. A request signal generating section 29 receives Vsync signal, generates a video data request signal (Vreq signal) to each plane and a line data request signal (HreqA-1) for each line of light emitting elements, and transmits them to the page memory control section. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
