摘要： Methods and apparatus for extending the reliability and usefulness of a fullwidth printhead by providing a redundant temporary replacement printhead module that can be positioned to compensate for missing or faulty jet nozzles. In order to take advantage of a single extra printhead module and to be able to compensate for more than a single failed nozzle, the replacement module is mounted on a separate translating x-axis and preferably provided with roll adjustment along another axis so that an effective spacing of nozzles in the replacement module can be adjusted to align with detected defective nozzles. The fullwidth printhead is formed from at least one array of smaller printhead modules. The arrays may be offset by a non-integer spacing interval of the individual nozzles. For example, if the nozzle spacing is S, the offset may be S/2. By virtue of the x-translation and roll capabilities, a single replacement module can accommodate replacement of one or several defective nozzles spaced closer together than the total length L of the replacement module, even if the defective nozzle(s) are located on different printhead modules and have a non-integer spacing.

摘要： A method for aligning printheads, some of which are arranged in an overlapped configuration, in a printer has been developed. The method includes identifying a stitch error for each color station in a plurality of color stations in the printer. The stitch error is identified with reference to shrinkage of a print medium as the print medium passes the plurality of color stations. A portion of the stitch error is used to move at least one printhead in the color station corresponding to the stitch error to compensate for a banding issue caused by the overlapped printhead configuration. All or part of the stitch error may also be applied to other printheads in the color station to compensate for possible color to color registration issues.

摘要： A method for operating an inkjet printer to form images that include both high density and low density segments has been developed. The method includes operating one printhead to eject ink drops with a large size to form high density segments of the image, and operating a second printhead to eject ink drops with a small size to form low density segments of the image. The large ink drops provide high coverage in the high density segments, and the small ink drops provide improved image quality in the low density segments of the image.
