Abstract:
A method for reducing artifacts in an electrophotographic printing system includes receiving a print job including image data for a set of pages. The electrophotographic printing system is used to print a block of pages from the print job to provide corresponding printed pages. Image data for the block of pages is analyzed to determine a cross-track image profile for each page in the block of pages. Image data for a compensation image and a number of compensation images are determined, wherein the compensation image has a cross-track image profile which has an inverted shape relative to an average of the cross-track image profiles for the block of pages. The printing of the compensation images reduces image burn-in artifacts which result from the printing of the block of pages.
