摘要： A method of printing with an ink jet printer compensates for skewed printing on a print medium. An image area is defined on the print medium which has a plurality of rows of pixel locations and a plurality of columns of pixel locations. A printhead includes a plurality of vertically adjacent ink emitting orifices arranged in an array having a height. The printhead is scanned during first and second scans across the print medium in directions transverse to the advance direction. The ink is jetted onto the print medium from the ink emitting orifices during the first and second scans at selected ink dot placement locations generally corresponding to one of the columns of pixel locations. An offset is determined in a transverse direction between a bottom ink dot placement location associated with the first scan and a top ink dot placement location associated with the second scan. The array of ink emitting orifices is segmented into at least two vertically adjacent segments of ink emitting orifices. The ink dot placement locations associated with at least one of the segments is shifted in a direction transverse to the advance direction a distance which is dependent upon the determined offset. The ink dot placement locations associated with at least one other of the segments remains unchanged. Printing on the print medium is carried out using the shifted ink dot placement locations.

摘要： The invention provides a flow feature structure for an ink jet printer. The structure includes a polymeric nozzle plate having a nozzle plate thickness, the nozzle plate containing a plurality of ink chambers, each ink chamber containing a nozzle hole in fluid communication therewith, a plurality of ink channels each having a channel width and an ink channel inlet for providing ink flow from an ink supply region to one each of the ink chambers and an air bubble interrupter device having a width dimension perpendicular to a flow axis through the ink channel. The width dimension of the air bubble interrupter is from about 0.5 to about 1.2 times the ink channel width and the interrupter device is disposed adjacent each of the ink channels and spaced from the ink channel inlet a distance of from about 0.5 to about 1.2 times the ink channel width. Such a structure provides improvement in ink flow by reducing the size of air bubbles which may form or accumulate in the flow areas of the nozzle plate so that the air bubbles do not block or inhibit the flow of ink to the ink chambers or affect the ejection of ink from the nozzle holes.

摘要： The invention provides a method for forming ink jet nozzle structures in an ablatable material. More particularly, the invention provides uniform nozzle structure by ablating an ablatable material with a laser beam while setting a field lens unit to various locations relative to a projection lens. The resulting ink jet nozzle structures have substantially orthogonal ink delivery trajectory paths relative to a plane defined by the length and width of the ablatable material regardless of the nozzles hole position relative to the edges of the ablatable material.

摘要： A method of determining the state of a printhead/cartridge in a thermal inkjet printer. An inkjet printhead undergoes a jetting operation in which a jetting frequency is selected and a corresponding steady state printhead temperature is known. The printhead is heated to the steady state temperature. Then the printhead is jetted with all nozzles for a predetermined period of time. Temperature samples from the printhead are obtained and the change in the printhead temperature for a short period of time is used to determine a slope in the temperature change. From the slope of printhead temperature changes, the ink flow rate through the printhead can be determined. The flow rate of ink through the printhead can be used to determine the various states of the printhead, including out of ink, clogged, deprimed, a taped printhead, etc.

摘要： A thermal ink jet printing apparatus maintains stable printing output as certain characteristics of the apparatus change over its operational lifetime. The apparatus includes an ink jet print head with resistive heating elements for receiving electrical energy pulses having a voltage level and for transferring heat energy pulses having a desired energy level into adjacent ink based on the electrical energy pulses. The print head includes nozzles associated with the resistive heating elements through which droplets of the ink are ejected when the heat energy pulses are transferred into the ink. The apparatus further includes a printer controller in electrical communication with the print head. The printer controller determines a pulse count indicative of a number of electrical energy pulses, applies the electrical energy pulses having a first pulse width to the resistive heating elements when the pulse count is less than a threshold value, and applies the electrical energy pulses having an adjusted pulse width to the resistive heating elements when the pulse count exceeds the threshold value. The difference in the first and the adjusted pulse widths compensates for changes in the electrical resistance of the resistive heating elements over time.
