摘要： Processes are presented for creating electronic banding compensation profiles for raster output scanner (ROS) devices by printing and scanning a test pattern having a series of strips extending along a process direction and spaced from one another along a cross process (fast scan) direction, analyzing the scanned data to determine facet-specific banding errors corresponding to individual strips, and selectively adjusting banding correction profiles to counteract the banding errors.

摘要： Xerographic machines can print documents that have unintentional streaking parallel to the process direction. There are many possible source of the streaking. Currently, the streaking is minimized by using a cross process direction dependent modulation, called a profile, to modulate a modulated light beam being scanned across the photoreceptor. The profile is purely a function of cross process direction position. The profile can minimize, and often eliminate, streaking for any one area coverage, but only for that one area coverage. Different profiles can be produced that work best for different area coverages. Choosing a profile from a group of profiles for use with each scan line can minimize parallel streaking for a wider range of area coverages.

摘要： A method and system for monitoring a print drum maintenance system of an image producing machine is disclosed herein in various embodiments. A test pattern is printed on the print drum, and imaged with an image-on-drum detector to determine a printed pattern response. The print drum is then cleaned again imaged with the image-on-drum detector to determine a cleaned print drum response. A cleaning efficiency is computed by comparing the imaged test pattern response to the imaged cleaned print drum response and determining if a failure condition exists by comparing the computed cleaning efficiency to predetermined limits. A corrective process is performed if the failure condition does exist, the corrective process including changing parameters of the drum maintenance system according to the computed cleaning efficiency. The changed parameters are compared to predetermined thresholds and, if not exceeding the thresholds, the cleaning is repeated after the parameters are changed.

摘要： Defects in an image forming system may give rise to visible streaks, or one-dimenisional defects in an image that run parallel to the process direction. One known method for compensating for streaks introduces a separate tone reproduction curve for each pixel column in the process direction. A compensation pattern according to this invention has alignment marks before and after a halftone compensation region. The alignment marks provide alignment between the printer pixel grid and a scanning pixel grid. The line width of each alignment mark and the gray level in each pixel column of each gray level portion is measured and analyzed to produce a local tone reproduction curve for each pixel column and associated line width. The line widths of the alignment marks can be remeasured to adjust the local tone reproduction curves to compensate for the streak defect when printing.
