    摘要： A dual-drop mode for a printer uses at least two full length waveforms and switches between the waveforms according to one or more patterning methodologies to print a page length document having a dual drop size print pattern across the printed portion of the page. This achieves printing from individual jet nozzles of either a large drop or a small drop. The page size patterning methodology is performed globally on at least a sub-page basis, rather than on a pixel-by-pixel basis and may be performed based on or independent of specific image data.

    摘要翻译： 用于打印机的双插入模式使用根据一种或多种图案化方法的波形之间的至少两个全长波形和开关，以在页面的打印部分上打印具有双墨滴尺寸打印图案的页长度文档。 这实现了从大滴或小滴的各个喷嘴喷嘴。 页面尺寸图案化方法在至少以子页为基础而不是逐个像素的基础上全局执行，并且可以基于特定图像数据或独立于特定图像数据来执行。

    摘要： A dual-drop mode for a printer uses at least two full length waveforms and switches between the waveforms according to one or more patterning methodologies to print a page length document having a dual drop size print pattern across the printed portion of the page. This achieves printing from individual jet nozzles of either a large drop or a small drop. The page size patterning methodology is performed globally on at least a sub-page basis, rather than on a pixel-by-pixel basis and may be performed based on or independent of specific image data. In exemplary embodiments, printing is achieved using multiple print passes, with at least two print passes using different sized ink droplets.

    摘要： A solid ink printer includes a solid ink measurement system that helps ensure an adequate supply of solid ink is in the feed channels delivering solid ink to a melting device within a printer. The solid ink measurement system includes a driving electrode mounted along a substantial length of a first structure of a first solid ink feed channel, a sensing electrode mounted along a substantial length of a second structure of the first solid ink feed channel, the sensing electrode being opposite and generally parallel to the driving electrode, an AC voltage source coupled to the driving electrode to generate an electrical field emitted from the driving electrode, and a capacitance measurement circuit coupled to the sensing electrode to receive an electrical signal induced in the sensing electrode by the electrical field generated by the driving electrode, the capacitance measurement circuit being configured to identify an amount of solid ink in the first feed channel that corresponds to the electrical signal received from the sensing electrode.
