摘要： A printer having precision ink drying capability and method of assembling the printer. The printer comprises a print head that is adapted to eject a plurality of ink drops through outlet orifices defined by the print head. The ink drops form a plurality of ink marks at a plurality of locations on a recording medium positioned opposite the outlet orifices. A plurality of heaters is disposed near the print head for heating the ink marks on the recording media in order to dry the ink marks. Drying the ink marks fixes the ink to the recording media. A plurality of sensors, that are disposed near the print head are also coupled to respective ones of the heaters for sensing the locations of the ink marks on the recording media. In addition, a controller interconnects each of the heaters to respective ones of the sensors for selectively energizing the heaters according to the locations of the ink marks sensed on the recording media by the sensors. Thus, the controller selectively informs the heaters of the locations of the ink marks on the recording media as the sensors sense the ink marks. In this manner, the heaters dry only the locations having ink marks with optimized energy output.
摘要翻译：具有精密油墨干燥能力的打印机和组装打印机的方法。打印机包括打印头，其适于通过由打印头限定的出口孔喷射多个墨滴。墨滴在与出口孔相对定位的记录介质上的多个位置处形成多个墨迹。多个加热器设置在打印头附近，用于加热记录介质上的墨迹以便干燥墨迹。干燥墨迹将墨水固定到记录介质上。设置在打印头附近的多个传感器也耦合到相应的加热器，用于感测记录介质上墨标记的位置。此外，控制器将每个加热器互连到相应的传感器，以根据由传感器感测在记录介质上的墨迹的位置来选择性地激励加热器。因此，当传感器感测到墨水标记时，控制器选择性地通知加热器墨水记录在记录介质上的位置。以这种方式，加热器仅干燥具有最佳能量输出的墨迹的位置。

摘要： A printing method that includes supplying ink from an ink reservoir through an ink channel that connects the ink reservoir with ink ejection chambers formed on a first surface of a substrate. The ink channel is connected at a first end to the ink reservoir and at a second end to a separate inlet passage for refilling each of the ink ejection chambers with ink. A group of the ink ejection chambers in adjacent relationship forms one of a plurality of primitives on the first surface of the substrate in which only a maximum of one of the ink ejection chambers is energized at a time. An ejection element within one of the ink ejection chambers is energized to cause the plurality of ink drops to be ejected onto a media surface at a single pixel location in a single pass of the substrate over the media surface.

摘要： Data input received by a printer is printed. Dot data, which indicates location of dots on a print medium, is generated from the data input. Dot shift data is used in order to make sub-pixel shifts in locations of a subset of the dots on the print medium. Pulses are provided to a printhead which result in ink being emitted through nozzles located on the printhead. When placing the dots on the print medium, sub-pixel shifts in locations of the subset of the dots is achieved by time shifting the occurrence of pulses used to generate the dots.

摘要： An inkjet print cartridge includes an ink supply and a substrate having a plurality of individual ink ejection chambers defined by a barrier layer formed on a first surface of the substrate and having an ink ejection element in each of the ink ejection chambers to eject ink drops. A nozzle having a plurality of ink orifices formed therein overlies the barrier layer with the orifices aligned and associated with the ink ejection chambers. An ink channel connects an ink supply. A group of the ink ejection chambers in adjacent relationship forms a primitive in which a maximum of only one ejection chamber in the primitive is energized at a time and the primitive is one of a plurality of primitives on the substrate. A first circuit on the substrate is connected to the ink ejection elements and a second circuit on the print cartridge is connected to the first circuit to transmit ejection signals to the ink ejection elements at high frequency. The first circuit applies primitive select signals to select one or more of the primitives and applies address line select signals to enable devices associated with the ink ejection elements in one or more of the selected primitives such that a maximum of one ink ejection chamber in a selected primitive is activated at a time.
