摘要： An ink-jet printer cartridge having a center reservoir chamber and two side reservoir chambers for holding inks of three different colors is provided with ink flow pathways of special configuration for connecting the reservoir chambers to exit ports at the print element. The ink flow pathways are provided with ridges extending along substantially their entire lengths so that air bubbles cannot completely block ink flow through the pathways. The ink flow pathways are disposed such that they have a vertical component of direction over their entire length and the pathways connecting the side reservoir chambers to exit ports include duct portions disposed at compound angles relative to the axes of the cartridge so that air bubbles, because of their buoyancy, will naturally tend to drift upwardly through the inclined ducts toward the reservoir chambers during normal usage, or drift toward the exit openings when the cartridge is inverted for priming. The duct portions of the ink flow pathways are generally trapezoidal in cross-section, the side walls intersecting the top wall at acute angles so that air bubbles cannot completely block the duct portions. The duct portions have end surfaces for directing air bubbles toward the reservoir chambers during priming, the end surfaces being end faces of plugs.

摘要： A printhead for an inkjet printer includes an ink reservoir and a plurality of nozzles for ejecting ink from the ink reservoir onto print media, the nozzles being formed in the ink jet printer printhead in a predetermined fashion with bores purposefully shaped and directed to determine the formation and placement of main drops and/or satellite droplets when ink is ejected from the ink reservoir when the printhead is part of an inkjet printer.

摘要： In an electrophotographic printer, a moving laser beam scans a photoconductor as the beam is selectively modulated by the operation of a beam modulator. Binary print data is gated to the modulator by the operation of a picture element (PEL) clock. At the beginning of each photoconductor scan, the beam traverses an optical grating that is constructed and arranged to produce a grating clock signal whose frequency and phase are accurately related to the later position of the beam during each photoconductor scan. A controllable delay means is controlled by the grating clock signal. For the scanning of each photoconductor row, the delay means operates to bring the phase of the PEL clock into synchronism with the grating clock signal, prior to the time that the beam scans the photoconductor.

摘要： This is an electronic scheme for correcting for mechanical misalignment and chromatic aberrations from laser beam to laser beam in the scan direction of a multiple beam laser scanning system for use in an electrophotographic machine. Each beam is first corrected for mechanical misalignment and thereafter for chromatic aberrations. A reference laser beam produces two pulses near the start of scan (SOS) and two pulses near the end of scan (EOS). A non-reference laser beam then produces SOS and EOS pulses from which the mechanical misalignment is calculated. A gated clock is energized by the reference pulse and a tapped delay line is used for nanosecond resolution. After accomplishing correction for mechanical misalignment, chromatic aberrations are corrected by measuring the amount of total pel displacement of the non-reference scan line relative to the reference scan line and inserting appropriate delays at selected intervals throughout the non-reference scan in order to maintain pel placement accuracy to a desired tolerance.
