摘要： A leveling and spreading system has been developed that enables the speed and position of the web to be determined from a sensor on a first roller. In a duplex print process, the first roller also reduces a temperature of the media web and an ink image printed in the first side print operation to within a first predetermined temperature range. A second roller modulates the temperature of the media web and ink ejected onto the media web immediately before the web enters the leveling and spreading system to within a second predetermined temperature range to enable uniformity of the ink and web temperatures for spreading the ink in a nip formed with a third roller.

摘要： A system and method for adjusting a transport path length of a continuous web of recording media in a printing system printing duplex images. The method includes detecting alignment marks, for instance top of form (TOF) marks, on the continuous web of print media and adjusting the path length to provide substantially accurate registration of first and second images on opposite sides of the web for duplex imaging. The system to adjust path length includes idler rollers movable with respect to turnbar rollers.

摘要： An inkjet offset printer includes a heated drum assembly having a hollow drum with an internal surface defining an internal cavity and a heater and a cooler located in the internal cavity. The heater includes at least one ceramic heater element. The cooler includes a slot to direct an air stream to the internal surface of the drum and aids in quenching the heating element for faster control responses.

摘要： A heater panel is configured to heat a print medium in a printer. The heater panel includes electrical conductors that form a plurality of heating zones to emit radiant energy toward the print medium. Heating zones that correspond to edges of the print medium emit radiant energy with a greater power density than heating zones that correspond to central portions of the print medium. The heater panel has a plurality of angled positions to vary the view factor for high gain control.

摘要： An inkjet printing system controls an ink droplet mass by regulating a pressure in an ink reservoir. The printing system includes an ink reservoir, an air pressure device, an ink ejection device, and a controller. The ink reservoir is configured to contain a supply of ink and an air space above the supply of ink. The air pressure device is fluidly coupled to the air space above the supply of ink. The ink ejection device is fluidly coupled to the ink reservoir to receive ink from the supply of ink and to eject ink droplets onto an image receiving surface. The controller is coupled to the air pressure device and is configured to activate the air pressure device selectively to change a mass of the ink droplets ejected by the ink ejection device.
