摘要： An inkjet printing device is arranged to employ a first set of multiple nozzle drop generators activated by a first address signal and a second set of multiple nozzle drop generators activated by a second address signal. The multiple nozzles of each drop generator of the first set are arranged in a predetermined geometric pattern, each of which encompasses at least one nozzle of a drop generator of the second set.

摘要： A printhead includes at least a first drop generator set and at least a second drop generator set. The first drop generator set includes a first type of drop generator, whereas the other drop generator sets include a second type of drop generator. The first and second types of drop generators are primarily different with regard to the drop weights they are capable of providing. Preferably, the first type of drop generator comprises a multi-nozzle configuration, whereas the second type comprises single nozzle configurations. In one embodiment, a first type of ink is ejected by the first type of drop generators and a second type of ink is ejected by the second type of drop generators. To prevent unwanted mixing of the black and color inks, a first orifice or nozzle layer is provided separate and apart from a second orifice layer. In this manner, a single printhead may be used for the delivery of both black and color inks.

摘要： The present invention is a printhead for ejecting fluid droplets. The printhead includes a chamber member defining a chamber. The chamber member has a chamber volume associated therewith. The chamber member defines an orifice and a fluid inlet through which fluid flows to the chamber. Also included is a heating member for heating fluid within the chamber. The chamber ejects a fluid droplet having a volume equal to the chamber volume in response to activation of the heating member.

摘要： In order to reduce particle clogging of ink firing chambers in an inkjet printer printhead, the barrier layer is configured to have a plurality of inner barrier islands, each associated with a respective one of the heater resistors, disposed between an ink firing chamber and the ink plenum, to form two ink feed channels. The two ink feed channels are designed to have a right angle turn to prevent particles from entering the ink firing chamber. A plurality of outer barrier islands, having a number equal to twice the number of inner barrier islands, are disposed between the inner barrier islands and the ink plenum, and are configured in lines parallel to the lines of heater resistors to prevent particles from reaching the ink feed channels.

摘要： A printhead for an inkjet printer employs non-circular orifices, such as oval or parallelogram, at the surface of the orifice plate to increase the restoring force of the ink meniscus. The reduced tail and diminished spray of an ink droplet expelled from the non-circular orifice results in improved edge roughness and improved quality of print.

摘要： A method and apparatus for improving ink-jet print quality uses a print head having an array using a plurality of nozzles in sets in each drop generator mechanism. Where a conventional ink-jet pen fires a single droplet of ink at a pixel per firing cycle, the present invention fires a plurality of droplets at different subdivisions of pixels. The particular array design may vary from ink-to-ink or pen-to-pen. Each drop generator of a print head array includes a plurality of nozzles wherein each of the nozzles has an exit orifice with an areal dimension, and produces an ink droplet that produces a dot on adjacent print media wherein the dot has an areal dimension, less than the areal dimension of a pixel to be printed. Dots are printed in a pattern for each pixel wherein print quality is achieved that approximates a higher resolution print made by conventional ink-jet methodologies.

摘要： A monitoring system monitors a pressure wave developed in the surrounding ambient environment during inkjet droplet formation. The monitoring system uses either acoustic, ultrasonic, or other pressure wave monitoring mechanisms, such as a laser vibrometer, an ultrasonic transducer, or an accelerometer sensor, for instance, a microphone to detect droplet formation. One sensor is incorporated in the printhead itself, while others may be located externally. The monitoring system generates information used to determine current levels of printhead performance, to which the printer may respond by adjusting print modes, servicing the printhead, adjusting droplet formation, or by providing an early warning before an inkjet cartridge is completely empty. During printhead manufacturing, an array of such sensors may be used in quality assurance to determine printhead performance. An inkjet printing mechanism is also equipped for using this monitoring system, and a monitoring method is also provided.
