    摘要: An image printing system configured to minimize two-dimensional image quality non-uniformities on printed documents is provided. The image printing system includes a marking engine, a linear array sensor, an image analyzer, and a controller. The marking engine is constructed to print toner images on an image bearing surface moving in a process direction. The marking engine comprising of a toner development system. The linear array sensor is adjacent the image bearing surface and is extending in a cross-process direction. The linear array sensor is configured to scan the toner image on the image bearing surface. The image analyzer is configured to detect a two-dimensional non-uniformity in the toner image. The controller is configured to control at least one control parameter of the toner development system based on the two-dimensional image quality non-uniformity in the toner image that is detected by the linear array sensor.

    摘要: A method of cleaning a heated drum within a continuous web printer includes operating an actuator to rotate a drum that is heated to a first temperature. The drum rotates in a process direction of a media web contacting the drum and heats the media web as the media web moves over a portion of the drum. The method also includes stopping movement of the media web, heating the drum to a second temperature that is greater than the first temperature, and operating the actuator to rotate the drum against a portion of the stopped media web to transfer ink from the drum to the portion of the stopped media web.

    摘要: A method enables an operator to detect misalignment of printheads that eject clear ink in an inkjet printer. The method prints a first test pattern with a first color of ink and then prints a second test pattern of clear ink on top of the first test pattern. The ink of the first and the second test patterns is then spread to enable the clear ink to be dispersed in interstitial spaces in the ink of the first color. An operator is then able to detect the spatial relationship of predetermined marks in the second test pattern to predetermined marks in the first test pattern. The predetermined marks of the first and the second test patterns are arranged to enable an operator to detect a misalignment distance and the inkjet printer uses the misalignment distance entered by the operator to adjust the alignment of the printheads that eject clear ink.

    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.
