    摘要： An improved method of measuring relative positions of adjacent printheads in a printhead array has been developed. A pair of ink dashes is made with different colors of ink from adjacent printheads and an offset distance between the dashes is determined from color density measurements of the two dashes. The offset distance may then be used to adjust the stitch alignment of the two printheads.

    摘要： A process for preparing an imaging surface of an imaging transfer member in a printing machine, the process comprises providing a surface roughness to the imaging surface to produce a plurality of pits having sharp features on the surface, and then exposing the pitted imaging surface to an acid dip for a time period sufficient to substantially reduce the sharp features on the imaging surface. This process may be followed by anodization. The process produces an imaging surface having a pit structure providing reduced oil consumption and wear of components of the printing machine that contact the imaging surface.

    摘要： A method of operating a printhead of an imaging device includes actuating a plurality of ink jets of the printhead to emit drops of ink onto an image receiving surface in accordance with a test pattern. The test pattern includes full pixel density areas and half pixel density areas that alternate in a process direction. Distances in a process direction between drops of the full pixel density areas and drops of the half pixel density areas in transition regions of the test pattern are then measured. The measured process direction distances are then correlated to a graininess level for the printhead.

    摘要： A banding adjustment method for an ink jet imaging device having a plurality of printheads comprises printing a plurality of test bands, each test band being printed by a plurality of printheads such that each printhead of the plurality prints a section of each test band. The drop mass generated by each printhead of the plurality is selectively adjusted between a default drop mass and an adjusted drop mass to print each test band of the plurality such that the plurality of printed test bands have various combinations of sections having the default drop mass and the adjusted drop mass. The user is then prompted to select a test band from the plurality of printed test bands.

    摘要： A method enables an ink jet imaging device to normalize the driving signals for the ink jets within a print head of the device. The method includes generating an ink jet driving signal at an initial voltage and a particular resolution, coupling the ink jet driving signal to an ink jet for selective emission of ink from the ink jet onto an ink receiver in accordance with the driving signal, scanning the ink receiver and generating a line discontinuity signal indicative of a number of discontinuities detected in a line formed on the ink receiver by the ink ejected from the ink jet, and adjusting one of a voltage and a resolution for the ink jet driving signal in response to the line discontinuity signal received from the scanner.

    摘要： A method of reducing intermittent weak or missing (IWM) jet failures in a phase change ink imaging device comprises fluidly connecting a positive pressure source to a print head assembly of a phase change ink imaging device. The print head assembly includes a plurality of ink jets for emitting ink drops onto an ink receiver. The method includes activating the pressure source to deliver a positive pressure pulse to the print head assembly. The pressure pulse is delivered at substantially a purge pressure. The pressure pulse has a pulse duration such that the pressure pulse bulges ink from the plurality of ink jets without emitting ink from the plurality of ink jets.
