    Abstract: A method for aligning multiple nozzle members in a solid free form build unit is disclosed. A geometric test shape having at least one investigational topographic region projecting outward from a central base is formed and analyzed for at least one physical characteristic correlative with nozzle member targeting accuracy. The physical characteristic is at least one of color hue shift, surface pattern irregularity, and dimensional accuracy.

    Abstract: A swath printer and printing method using multiple printmodes per swath to improve printing time for print data that contains a mix of monochrome regions such as text, and color regions such as photographic images. Monochrome regions typically can be printed with a given print quality level using a fewer number of scans or passes over the area than can color regions. Throughput can be improved by identifying color and monochrome regions of each swath, and switching printmodes when printing these different areas of the swath. Because reversing direction at region boundaries in the middle of a swath can adversely affect printing throughput, the ratio of the size of monochrome regions to color regions is analyzed to ensure that throughput will be improved before enabling multiple printmode per swath mode. A number of different combinations of monochrome printmodes and color printmodes can be advantageously implemented.

    Abstract translation: 每个条带使用多个打印模式的条带打印机和打印方法，以提高包含单色区域（如文本）和彩色区域（如摄影图像）混合的打印数据的打印时间。 单色区域通常可以以给定的打印质量水平打印，使用比颜色区域少的扫描或通过区域。 可以通过识别每个条带的颜色和单色区域以及打印这些不同区域的条带来切换打印模式来改善吞吐量。 由于在一个条纹中间的区域边界处的反转方向可能不利地影响打印吞吐量，因此分析单色区域与颜色区域的大小的比率，以确保在每个条带模式启用多个打印模式之前提高吞吐量。 可以有利地实现许多不同的单色打印模式和彩色打印模式的组合。

    Abstract: The gauging method generally follows a drop count approach to ink level gauging while making more precise the relationship between the expelled-drop count and the weight of ink actually expelled, thereby to provide more accurate ink level gauging. The printhead temperature is monitored as each swath of an image is printed. Moreover, temperature variations that occur within each swath are noted so that the corresponding intra-swath variations in drop weight are factored into the calculation of a net ink drop weight that more closely approximates the drop weight actually ejected. The method also factors in the effect that printing frequency has on drop weight.

    Abstract: An inkjet printer uses a printhead that passes repeatedly across a print medium in individual swaths. The printhead has individual nozzles that are fired repeatedly during each printhead swath to apply an ink pattern to the print medium. Before any given swath, the printer analyzes factors that might require a reduction in print density. Anticipated printhead temperature is one factor that might require a reduction in print density. The printer monitors the print density and peak printhead temperature during each printhead swath. It then uses these values to calculate, prior to each new swath, a maximum permissible print density. If a reduction in print density is required, the printer temporarily disables selected nozzles to produce a reduced-height swath rather than pausing between swaths or reducing the printhead velocity relative to the page.

    Abstract: A method and apparatus for determining an optimum print density for an ink jet printer uses characteristics of a printer and its peripheral components such as an ink jet printhead, and an ink supply unit to reach an optimum print density. The ink jet printer receives a print command from a computer. The printer reads an ink drop volume parameter from a printhead memory device on the ink jet printhead and stores this parameter in a printer memory device on the ink jet printer. The processor in the printer determines an ink density compensation value for the ink jet printhead based on the ink drop volume parameter. The processor on the ink jet printer applies the ink density compensation value to the print command, thereby creating a depleted print command. Finally, the depleted print command is printed.
