    摘要： An ink stick for use in a phase change ink jet printer is provided wherein the ink jet printer has an ink feed channel having a feed direction leading to a melt plate. The ink stick comprises an ink stick body having an external surface and an axis of rotation. The ink stick body is adapted for insertion into the ink feed channel so that the axis of rotation is oriented substantially perpendicular to the feed direction. The external surface of the ink stick body forms a circle on a plane that is substantially perpendicular to the axis of rotation.

    摘要： An ink level sensing system and method of sensing that includes a lower probe positioned in a lower portion of an ink reservoir, an upper probe positioned above the lower probe and extending upward to an upper portion of the ink reservoir, and an electrode positioned next to the lower and upper probes. An electrical signal is driven to the electrode and current flows are detected from the electrode to the lower and upper probes. The current flows to the lower and upper probes are compared to determine a level of ink in the ink reservoir.

    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： A low cost, fully automatic, thickness detection system, readily integrated into an existing paper path sheet transport, in which a regular and known small displacement signal is generated, compared, combined and/or superimposed on the signals from the small displacement of a sheet transport element with differences in sheet thickness. Even sub-millimeter sheet thicknesses can be measured of sheets moving through a regular sheet feeding nip with nip idler roller displacement using a low-cost sensor, where that sensor is additionally repetitively actuated by known small movements to provide calibration signals, such as those provided by plural small radius differences of a rotating idler roller shaft area which will enable existing idler and idler shaft run-out movement error noise signals to be overcome.
