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： One aspect of the invention checks mechanical misalignment of plural pens and shifts data to allow for at least part of misalignment—and automatically prints images with the shifted data. If pens are aligned within a dot row then preferably the image prints without data shift. In one other preference, the pens print respective ink types; in this regard a particular preference is that the inks include plural colors, or alternatively plural dilutions. The invention is particularly beneficial in printing on a particular printing medium that is insensitive to relative timing of deposition of ink types; in this case an ideal print medium is plain paper. In some such situations the data shift best compensates for only part of misalignment, and pen-nozzle selections for the rest. In other situations the shifting step best compensates for all the misalignment. In another aspect, the invention extends marking element life and thereby printhead life by distributing usage over a maximum number of elements. This is accomplished by a system that checks misalignment and shifts data, as above. Alternative preferences for finding alignment include data encoded on pens and a reader of the encoded data; or a system that uses the pens to print a test pattern and reads it to find alignment. A hardware aspect of the invention includes parts of a processor programmed to check alignment and print with essentially all nozzles, taking alignment into account.

摘要： A media print system includes a first print unit, a second print unit, at least one actuator configured to move the first unit and the second unit relative to one another and a controller configured to generate control signals. The at least one actuator positions the first unit and the second unit at the first and second positions, respectively, during a first longitudinal pass of a medium and positions the first unit at a third position during a second longitudinal pass of the medium in response to the control signals.

摘要： Throughput of imperfectly aligned plural multinozzle pens is optimized by determining pen-to-pen mechanical misalignment, ascertaining the maximum number of nozzles that can be used while printing with the used nozzles of all pens substantially aligned (and without shift of data), and then automatically printing with that maximum number of nozzles. Preferably if the determining step finds that the pens are aligned within a dot row, all the nozzles can be used and the print step prints with all nozzles. Also preferably the print step includes automatically using a printmode that specifically accommodates the ascertained maximum number of nozzles. It is preferred that each pen have a few hundred nozzles, all the pens be in mechanical alignment within a few nozzle spacings, and the ascertaining step include eliminating from printing use only at most a few nozzles that are outside the mechanical alignment. Preferably thus the eliminated few nozzles, of the few hundred in each pen, most typically amount to roughly one percent of all nozzles; and the maximum possible number eliminated is roughly three percent of all nozzles. In other aspects of the invention, a printer with plural multielement heads, each having multiple marking elements, is improved by reducing average wear and thus extending average useful life of each element. This is accomplished by distributing usage over a maximum number of marking elements.
