摘要： A method for minimizing cross-process non-uniformities in solid and heavy shadow regions of printed documents is provided. The method includes marking with a marking engine an image on an image bearing surface moving in a process direction; generating profile data of the image by sensing an optical characteristic of the image in a cross-process direction; adjusting at least one control actuator of the marking engine so as to shift the characteristic of a subsequent marked image in the cross-process direction to at least a target value; and generating a spatially varying tone reproduction curve to smooth the characteristic of the subsequent marked image towards the target value.

摘要： A method and system for controlling an image printing system in the presence of reload defects are provided. The method comprises placing toner images on an image bearing surface moving in a process direction, determining the density of the toner image or a portion thereof being printed on the image bearing surface, and printing a scheduled control patch at a location in the cross-process direction on the image bearing surface, wherein the location where each control patch is printed is dynamically changed based on the density of the toner image adjacent the control patch or a portion thereof.

摘要： The life of the photoconductor in an image forming apparatus is typically limited by the eventual occurrence of some form of print quality defect related to the photoconductor. One of the typical failure mechanisms is the slow wearing away of the surface layer of the photoconductor. Photoconductor run life is improved by operating a charging station in a low wear mode during certain circumstances, including: during printing of a low stress page as detected based on the image data; during at least one of cycle up and cycle down operations to control charging of the at least one photoconductor over at least one print zone for at least one cycle of rotation of the at least one photoconductor; during printing of at least one test patch in a process control cycle; and upon determination from the image data that at least one photoconductor will not contribute to the printing during a next print cycle.

摘要： A xerographic marking engine adjusts a charging actuator, such as an AC peak-to-peak voltage or an AC peak-to-peak AC current, based upon toner patch density measurements made using, e.g., a toner patch density sensor. The sensor is used to detect a knee in a toner mass density curve obtained by sweeping an AC peak-to-peak voltage or an AC peak-to-peak current. Once the knee is located, an AC charging actuator peak-to-peak voltage or AC peak-to-peak current is determined that reduces the amount of positive charge that is deposited onto the surface of the photoconductor, thereby extending its life while maintaining acceptable print quality. The described approach may improve photoconductor life without significantly increasing production costs or complexity.
