摘要： An apparatus for controlling ink pressure in a printhead, the apparatus comprising: an integrally formed structure having: at least one control reservoir separated into first and second chambers by a weir; at least one inlet passageway, extending from the first chamber to an inlet port on an edge of the structure, for supplying ink from a remote source into the first chamber of the reservoir; at least one fluid outlet passageway, extending from the second chamber to an outlet port on an edge of the structure, for recirculating fluid from the reservoir to the remote source of ink; and at least one ink supply port, in communication with the first chamber, for supplying ink to, or receiving ink from, a printhead.

摘要： A method of reducing and/or preventing the accumulation of concentrated ink at an ejection point of a printhead of an electrostatic inkjet printer when ink is not being ejected at the ejection point, the method comprising reversing the electric field at the ejection point of the printhead during a non-printing phase of operation to reduce the concentration of ink at the ejection point.

摘要： A method of cleaning an electrostatic printhead which has one or more ejection tips from which, in use, ink is ejected, the method comprising: stopping a prior flow of ink to a region around the ejection tip(s) for, in use, printing; causing a pressure differential to occur at the tip region thereby causing the ink meniscus to retreat from the tip; and passing a rinse into the tip region to clean the tip.

摘要： The invention relates to a method of printing a two-dimensional bit-mapped image having a number of pixels per row, the printhead having a row of ejection channels and each ejection channel having associated ejection electrodes to which voltages are applied in use. During printing, in order to cause volumes of fluid to be ejected from selected ejection channels of the printhead for printing, voltage pulses having values of predetermined amplitude and duration as determined by respective image pixel bit values generated by a raster image processor are applied, at a given pulse period, to the electrodes of the selected ejection channels. The part of the raster image corresponding to an ejection channel is scanned to determine the number of adjacent non-printing pixel periods prior to a pixel to be printed and, immediately prior to the printing of said pixel, a voltage pulse, having a value predetermined in accordance with the time, measured in units of the given pixel period, between the last pixel to be printed and said pixel to be printed, is applied to the ejection electrode.
