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.

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.

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 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 of operating an ink jet printer including printing a first image having substantially solid fill regions on a transfer surface disposed on a print drum, printing a second image on the first image, wherein the second image comprises solid or dithered fill regions that correspond to portions of some of the solid fill regions of the interlaced image, and wherein the second image has a dot density that is less than a dot density of the first image.
摘要:
An inkjet printer is configured to process print media having an ink image differently to alter a gloss level of the ink image on the print media. In one mode of operation, the printer moves print media bearing an ink image on one side only through a transfix nip a second time to reduce a gloss level of the printed image.
摘要:
A method for performing duplex printing enables increased throughput in an indirect printing system. The method includes measuring a coverage parameter for image data to be printed, and transforming operation of the printer from a first printing process timing sequence to a second printing process timing sequence in response to the coverage parameter exceeding a predetermined threshold.
摘要:
A print system has a print engine, a presence detector and a controller. The controller receives the signal from the detector, accesses past usage data, and combines the signal and the usage data to adjust operations of the print engine.
