摘要： An inkjet nozzle device includes a main chamber having a floor, a roof and a perimeter wall extending between the floor and the roof. The main chamber includes: a firing chamber having a nozzle aperture defined in the roof and an actuator for ejection of ink through the nozzle aperture; an antechamber for supplying ink to the firing chamber, the antechamber having a main chamber inlet defined in the floor; and a baffle structure partitioning the main chamber to define the firing chamber and the antechamber, the baffle structure extending between the floor and the roof. The firing chamber and the antechamber have a common plane of symmetry.

摘要： A method of printing from a fixed inkjet printhead having a plurality of ink planes. The method includes the steps of: feeding a print medium past the printhead in a media feed direction, the media feed direction defining relative upstream and downstream sides of the printhead; printing an image onto the print medium, the image being defined by image data; and printing a keep-wet pattern onto the print medium from each ink plane of the printhead, the keep-wet pattern being defined by a plurality of dots printed at a frequency sufficient to maintain hydration of each nozzle in the printhead. A first keep-wet pattern from a first ink plane is printed at a higher frequency than a second keep-wet pattern from a second ink plane, the first ink plane being furthest upstream in the printhead.
摘要翻译：一种从具有多个墨平面的固定喷墨打印头进行打印的方法。该方法包括以下步骤：将介质通过打印头沿介质进给方向进给，介质进给方向限定打印头的相对上游和下游侧; 将图像打印到打印介质上，图像由图像数据定义; 并且从打印头的每个墨平面将打印介质上的保湿图案印刷到打印介质上，保持湿图案由以足以维持每个喷嘴在打印头中的水合的频率打印的多个点来限定。来自第一墨平面的第一保湿图案以比来自第二墨平面的第二保湿图案更高的频率印刷，第一墨平面在打印头中最上游。

摘要： A method of generating print data for an inkjet printhead having a plurality of ink planes. The method includes the steps of: receiving image data for a print job in a printer controller; retrieving keep-wet pattern data for each ink plane of the printhead, the retrieved keep-wet pattern data being determined using one or more input parameters; generating first print data for each ink plane in the printer controller based on the received image data; merging the first print data with the keep-wet pattern data to provide second print data for each ink plane; and sending the second print data from the printer controller to the printhead, thereby causing the printhead to print an image together with a keep-wet pattern. The keep-wet pattern is defined by a plurality of dots printed at a frequency sufficient to maintain hydration of each nozzle in the printhead.
