    摘要： A method for locating a cutter in a web fed photo imaging system including the steps of measuring an actual fiducial distance between consecutive fiducials, comparing a measured actual fiducial distance between consecutive fiducials to an imaging engine feed distance, calculating a feed distance scaling factor equal to a difference between an average actual fiducial distance and the imaging engine feed distance divided by a total number of discrete incremental moves between fiducials and adjusting the imaging engine feed distance in an amount equal to the scaling factor.

    摘要： A method for calibrating one or more printheads includes printing a reference image using a first portion of image forming points of a first printhead, printing a diagnostic image using a second portion of image forming points of either the first printhead or a second printhead, detecting an optical density of the combined reference image and the diagnostic image and determining a compensation value based upon the optical density.

    摘要： A method of compensating for thermally induced misalignments in a printing system includes measuring two or more temperatures of a structure within the printing system, mathematically differencing the two or more temperatures to produce a differenced value, inputting the differenced value into a correlation equation, the correlation equation predicting a misalignment of a target printing system component, and compensating for the predicted misalignment of the target printing system component.

    摘要： Exemplary embodiments of the invention include systems and methods of reducing visible print defects in drum printers having multi-die printheads oriented substantially perpendicular to the print media path. The exemplary embodiments include printing very small amounts of additional ink via empirically determined printing masks in addition to the normal image content, such that the print defects become less visible. Further exemplary embodiments include printing the additional ink during times typically utilized for print drying.

    摘要： A system is provided that includes an encoder strip having encoder markings and at least a first index marking along a length of the encoder strip, an encoder configured to generate a first signal that indicates detection of the encoder markings in response to being moved along the length of the encoder strip, an index sensor configured to generate a second signal that indicates detection of the first index marking in response to being moved along the length of the encoder strip in unison with the encoder, and processing circuitry configured to determine a first encoder index value that corresponds to a center of the first index marking using the first and the second signals.
