摘要： A printer includes an image drum temperature regulation system that helps reduce thermal gradients on the image drum surface. The image drum temperature regulation system includes a feedback controller and a feed-forward controller. The image drum temperature regulation system operates the heaters and fan of the image drum with reference to a temperature difference between actual temperature of the image drum and a temperature setpoint and to the thermal effect of ejecting an ink image onto the image drum.

摘要： An ink jet imaging system comprises a heated imaging drum that rotates in at least one direction, a print head for ejecting ink onto the heated imaging drum as it rotates past the print head to form an image, a media sheet transport for synchronizing movement of a media sheet with rotation of the heated imaging drum, a transfixing roller that forms a transfixing nip with the heated imaging drum to transfix the image on the rotating heated image drum onto the media sheet synchronized by the media sheet transport, and a media director located between the media sheet transport and the heated imaging drum to direct the media sheet into close proximity with the heated imaging drum at a position sufficiently prior to the transfixing nip that the heated imaging drum heats the media sheet before the media sheet enters the transfixing nip.

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.
