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.

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 printer comprises a print engine and a print head. The print engine separates combined image/dot pattern data into image data and dot pattern data. The print engine separately processes the image data and the dot pattern data and merges the separately-processed image data and dot pattern into print data for printing. A print head prints the print data.

摘要： A method and apparatus are disclosed for calibrating a digital printer to provide a substantially aim printer response. A test target is processed through a set of potential calibration functions to form a set of processed test targets and the set of processed test targets is printed using the digital printer. Thereafter, the set of printed test targets is measured to determine the printer response. An error criterion is determined for each measured test target by comparing the measured printer response for each of the set of potential calibration functions to the aim printer response. The calibration function which has the smallest value of the error criterion is then selected.

摘要： A sweep speed is determined for sweeping a printer head of a printer across a print medium for printing a swath of an image on the print medium. A distance by which to advance the print medium is at least partially determined in accordance with the determined sweep speed and the print medium is advanced by the determined distance.
