  • Systems and methods for reducing cross process direction registration errors of a printhead using a linear array sensor
    Publication number: 20080062219
    Abstract: Systems and methods are provided for determining registration errors in the cross process direction of a printer. A first straight line is obtained by detecting line centers of a first plurality of dashes in a test pattern. A second straight line is obtained by detecting a line center positions of a second plurality of dashes in the test pattern. A difference between the off-set of the first straight line and the off-set of the second straight line is used in determining registration errors.

  • Systems and methods for detecting intermittent, weak and missing jets with an inline linear array sensor
    Publication number: 20060114284
    Abstract: Systems and methods are provided for detecting intermittent, weak or missing jets of a printer. The detection is implemented using a test pattern. Detected failed jets may be confirmed using a verification target. A printhead containing nozzles corresponding to detected failed jets may be wiped or purged.

  • Systems and methods for reducing process direction registration errors of a printhead using a linear array sensor
    Publication number: 20060114283
    Abstract: Systems and methods are provided for detecting process direction registration errors in a printer. The errors are detected by analyzing a metric of a dash minimum response obtained from a test pattern. The test pattern contains dashes. At least one dash is shifted in the process direction in relation to another dash.

  • Systems and methods for sensing skew and bow of a raster optical scanner using a full width array detector
    Publication number: 20060114308
    Abstract: System and methods are provided for detecting color separation misalignment in raster optical scanners. A dash minimum response curve is obtained from a plurality of minimal responses sensed from a plurality of dashes in a test pattern. The frequency of the dash minimum response curve a is used to detect skew or bow, depending on whether the frequency is a constant or a variable.
