    摘要： In color printing with a color registration system for the registration of plural color images on an image bearing surface, such as a photoreceptor belt of a color printer, registration marks are imaged on the image bearing surface, which registration marks correspond to the color images and are sensed by a registration marks sensor. In an initial gross registration mode the system first automatically images first registration marks, in the form of expanded chevron targets, which are greatly expanded in the process direction so as to avoid overlapping marks even if there is initial gross misregistration, to thus provide wider initial misregistration latitude for the sensor. When an acceptable initial registration is achieved, the system automatically switches to imaging more closely spaced and more frequent second registration marks, preferably regular chevron targets, providing higher registration accuracy. These registration targets may be generated along opposite sides of the image areas, on opposite sides of the photoreceptor or other image bearing surface in the process direction.

    摘要： Initial setup of image to sheet (IOS) or image to paper (IOP) registration in a printing device such as, for example, an electrographic printer, is accomplished in a single step that uses an initial set of measurements to determine and correct each of the independent registration errors, including image squareness/ROS skew, image skew/paper skew, lateral magnification, process magnification, lateral direction IOS or IOP position, and process direction IOS or IOP position simultaneously. A set of algorithms is used to perform a series of geometrical transformations to determine each of the six errors affecting IOS or IOP registration.

    摘要： The relationship between first and second side images is evaluated to determine how the position of the paper and/or the size and arrangement of an image can be manipulated to compensate for paper shrinkage caused by fusing. Show through is reduced by performing setup to adjust a pixel clock frequency and/or a photoreceptor speed, determining a residual magnification error, determining margin shifts to compensate for the residual magnification error, and applying the margin shifts. Paper shrink effects on registration can be compensated for using determinations made during a typical printer setup. Show through errors can be reduced without using a paper conditioner to pre-shrink or re-wet the paper. In simplex and duplex printing, the show through errors worsen as the image moves away from the registration edge. Using information obtained during setup, a margin shift is determined that results in a significant reduction in the maximum show through for each image.

    摘要： A color registration method, system, and computer program product generally includes a plurality of imaging stations and one or more MOB (Marks-On Belt) sensors. An indication is initially provided to each imaging station among the imaging stations, which colors among a plurality of colors associated with said color registration system are active. Next, an arbitrary imaging station among the imaging stations can be assigned as a reference color. Thereafter, the arbitrary imaging station can be instructed to write an appropriate color pattern to replace marks associated with any imaging among imaging stations not enabled with the marks with respect to said reference color in order to thereby produce a resulting color ensemble that is detectable by one or more MOB sensors.

    摘要： Systems and methods are described that facilitate correcting for paper process direction arrival errors during a print job in a marker module of a print engine. Paper sheet arrival time is determined at a first registration point in a print engine or marker module thereof, and an average arrival time is compared to an expected arrival time to determine whether the pages are arriving on time, early, or late. The arrival time error is used to generate or look up a correction factor, which is added to an expected arrival time at a second registration point in the marker module or print engine to generate an updated expected arrival time. Print engine control parameters (e.g., sheet feeder timing, toner application, paper path speed, etc.) are adjusted according to the updated expected arrival time at the second registration point.

    摘要： A calibration procedure for the synchronization of photoreceptor belt seams of tandem marking devices at system cycle-up. The procedure allows for images projected upon equivalent image panels relative to the belt seams of the tandem engines to be printed on the same sheet. The successive image panels on each belt are of relatively equal distance from the respective belt seams. Thus there is less frequency of the need to skip pitches in the printing operation to avoid either imaging on a belt seam or having the sheet arrive outside the input timing window for second engine sheet registration.
