摘要： A method for determining the skew of a printhead of a printer. At least three images are printed which are at least partially aligned substantially along the printhead scan direction with the middle image printed from one of the upper and lower portions of the printhead and with the adjacent images printed from the other of the upper and lower portions of the printhead. A sensor is moved in the printhead scan direction over the images. A function is calculated from the sensor output, wherein the calculated function indicates the skew of the printhead.

摘要： A method for determining vertical misalignment between first and second print heads involves printing a test pattern of first and second alternating slanted blocks extending horizontally. The first slanted blocks are printed by the first print head and the second slanted blocks are printed by the second print head. A known edge angle of the first and second slanted blocks is substantially the same. A sensor is moved across the test pattern for evaluating misalignment.

摘要： A printhead alignment test pattern has spaced-apart images at least partially aligned along an axis. Each image includes leading and trailing edge portions having respective image-outermost leading and trailing edges spaced apart along the axis and includes an intervening portion located between the leading and trailing edge portions. The leading and trailing edge portions have a higher print density than the intervening portion. A method for determining a printhead misalignment of a printer prints the test pattern, moves a sensor along the axis over the images, obtains data from the sensor, determines the locations along the printhead scan axis of the leading and/or trailing edges of the images using the data, and calculates the printhead misalignment from the determined locations of the leading and/or trailing edges of the images. The test pattern reduces cockling of the print media which improves the accuracy of the method.

摘要： A method for determining a printhead misalignment of a printer. One step includes printing a printhead alignment test pattern including spaced-apart images at least partially aligned substantially along a printhead scan axis. A sensor is moved along the printhead scan axis at a known speed over the plurality of images. Sampled data points are obtained from the sensor at a known sampling rate. Another step includes determining the locations along the printhead scan axis of the edges of the images using the sampled data points, the known speed of the sensor, and the known sampling rate. An additional step includes calculating the printhead misalignment from the determined locations of the edges of the images.
