摘要： An inkjet offset printer includes at least one printhead to eject ink on a release agent applied to an image receiving member for subsequent transfer of the ink to the surface of a recording media. The release agent is applied to the image receiving member by at least two release agent applicators. The release agent can be selectively applied to process sheets of recording media of different sizes to improve print quality. Selective application of release agent to the image receiving member prevents release agent from migrating to a transfix roll, and subsequently to the back side of the media which affects the image quality.

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.

摘要： A dynamic positional shifting, in the process direction, of the images on the second print engine of a tandem machine printing system in order to increase the time (and number of prints) between skipped pitches. Although the photoreceptor belts of each print engine may be out-of-phase, the relative positions of their individual seam zones may be derived during cycle-up. A control procedure then optimizes the position and spacing of each image within each belt revolution of the second engine, while still maintaining the minimum inter-document zone (IDZ) length required for paper path feeding and registration, xerographic process controls, and finishing. Removing the constraints of fixed-dimension IDZ's, as well as being able to adjust spacing and length of individual images on the belt, allows for optimization of system productivity by either delaying or eliminating the need for a skipped pitch.

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 method of correcting output image squareness in a laser printer system having a Raster Output Scanning (ROS) device with a pivotal mounting. The method includes printing a test pattern that includes a plurality of markers printed in a predetermined geometric arrangement and calculating a skew angle based on the measured distances, preferably using the Law of Cosines. The ROS device is then automatically rotated by an amount sufficient to correct the skew angle. The ROS rotation is performed automatically by an adjustment system connected to the ROS. The method optionally includes a scanner for scanning the test pattern image and making the measurements automatically via a program configured to analyze the scanned image.

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： 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.
