    摘要： A temperature control system for an inkjet printhead assembly includes a printhead assembly having ink ejection elements energizable by an electrical pulse having an amplitude and pulse width, a sensor coupled to the printhead assembly for generating a signal representative of a printhead temperature. A controller reads a nominal operating pulse width, pulse width calibration data and the signal from the sensor. The controller calculates an adjusted pulse width using the nominal operating pulse width, the pulse width calibration data and the signal from the sensor. The controller uses the adjusted pulse width to control the printhead temperature.

    摘要： A printhead for an inkjet printer having geometric features which reduce drop placement error of main and satellite drops ejected from the nozzles of the printhead. Nozzles that are tilted along an axis corresponding to the direction of scanning of the printhead while printing have reduced drop placement error in the orthogonal direction to the scanning, and create a breakoff velocity for the satellite drop that can cause the main and satellite drops to be placed in a coincident location on the medium in one of the directions of scanning, thus forming desireable round printed spots and reducing drop placement error in the scan direction. These improvements can be repeatably achieved for all nozzles. Nozzles with non-circular and asymmetric bores also reduce drop placement errors, particularly when these types of nozzles are also tilted.

    摘要： Described is a method for incremental printing with an inkjet swath printer by depositing multiple drops of an ink from a printhead in each column of an image, in each scanning pass of the printhead over a print medium by obtaining the image, analyzing the image to determine which drops of ink will define leading and trailing edges in each row of the image element with respect to a scanning direction, removing at least one drop of ink preceding the drop defining the trailing edges in each of the rows, removing at least one drop of ink after the drop defining the leading edges in each of the rows and depositing the remaining drops of the ink on the medium while passing the printhead over the media in the scanning direction. Also described is a method of printing with an inkjet printing system scanning over a print medium by providing a printhead having a supply of ink and a plurality of ink ejection chambers for ejecting ink onto the print medium, each of the ink ejection chambers depositing the ink onto a corresponding row, the ink ejection chambers ejecting ink drops in a range of frequencies between a base firing frequency and a maximum firing frequency, obtaining an image, analyzing the image to determine which drops of ink will define leading and trailing edges in each row of the image element with respect to a scanning direction, ejecting the drops of ink defining the leading trailing edges in each of the rows at an ejection frequency less than the maximum frequency and depositing the remaining drops of the ink on the medium while passing the printhead over the media in the scanning direction.
