摘要： A method and apparatus for analyzing images deposited on an image receiving member of a printer, and more particularly analyzing images deposited on a surface of an imaging drum in an inkjet printer. A photoelectric sensor supported by a sled in contact with the surface of the imaging drum can be used to detect missing jets in the printhead, to align the printhead, to reduce the amount of purged ink, and to determine run out of the imaging drum.

摘要： A method for forming a print head having a plurality of reentrant structures to reduce wetting of the print head surface by the ink during use, and a resulting structure. The method can include the use of a single photosensitive layer to form plurality of reentrant structures, each having a pillar and a cap which overhangs the pillar. A plurality of print head nozzles can also be formed during the formation of the reentrant structures. Embodiments can include the formation of pillars, caps, and nozzles using three different masks, two different masks, or a single mask.

摘要： An encoder home position sensing system and method is disclosed, which includes the use of an analog quadrature encoder reader and either a code wheel or a code strip. The code wheel possesses an optical track comprised of annular ring patterns, the thickness of which can be modulated by a sinusoidal function about the code wheel circumference, with one cycle of a sine wave corresponding to one encoder cycle. In one region of the optical track the amplitude of the sine function is changed to imbed an absolute reference home position. This region of the optical track can be sensed and used to determine an absolute system position. The linear code strip is similarly constructed with lines along the direction of motion, the thickness of which are modulated with a sine function, with one cycle of the sine wave corresponding to one encoder cycle, and the amplitude of the sine wave function changed to imbed an absolute reference home position in the optical track.

摘要： A method of operating a printer turns off a support structure heater when the printer enters standby mode. The print head is then moved away from an intermediate transfer surface supported by a support structure. Heat settings used to heat a print head are then varied to heat the print head and the support structure. Another method of operating a printer turns off a support structure heater when the printer enters standby mode and holds a print head adjacent to an intermediate transfer surface while the printer is in standby mode.

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： 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.
