    Abstract: In a phase-change ink image producing machine, better control flow of molten solid ink may be provided by a solid ink valve system including a valve plate (600) with one or more valve ports (610), an umbilical connector (630), and a valve (620) positioned between the valve plate and the umbilical connector, Ink flow between the valve plate (600) and the umbilical connector (630) may be asynchronously regulated by actuating the valve. Such actuation may be performed by heating and cooling the valve, by applying electric current to a coil that surrounds a valve element of the valve and to a wire provided in the valve element and/or by asynchronously actuating a valve associated with the valve port.

    IPC: B41J2/175

    Abstract: A method for delivering molten ink to a printing mechanism alternates between a first and second reservoir receiving molten ink from a receiving ink reservoir while providing ink from the other of the first and second reservoirs to a printing mechanism. The alternation of the two reservoirs is achieved with coordinated operation of two actuators operatively connected to two seal members.

    Abstract: A high shear ball check valve device is provided and is suitable for use in a liquid ink image producing machine to quickly and precisely control flow of liquid ink. The high shear ball check valve device includes a valve housing defining a valve chamber. The valve chamber has a desired cross-dimension, an inlet end, and an outlet end. The high shear ball check valve device also includes an inlet member that is connected to the inlet end of the valve housing and has an inlet opening and a ball seat and seal portion surrounding the inlet opening. The ball seat and seal portion has a desired first durometer hardness value. The high shear ball check valve device next includes a valve ball having a desired diameter and being located movably within the valve chamber, and an outlet opening located at the outlet end of the valve chamber. The outlet opening has a rectangular shape, and a size that is slightly greater than the diameter of the valve ball, for creating a backward fluid flow pattern that results in relatively high shear stress on the valve ball. The relatively high shear stress thereby quickly moves the valve ball away from the outlet opening and back against the ball seat and seal portion to shut off the inlet opening.

    Abstract: PROBLEM TO BE SOLVED: To provide a continuous media web heater which permits faster temperature adjustment for heating a moving web having no necessity of changing a set temperature of the heater.
    SOLUTION: A radiation heating unit 104 comprises a housing 114 having an opening 140 for locating the radiation heating unit adjacently to a media web 20 in an image apparatus. A pair of radiation heating panels 118 can be located on any one of a plurality of positions between and including a fully open position in which the pair of radiation heating panels 118 are arranged side by side in the opening 140 of the housing 114 and face the media web 20 and a retracted position in which the pair of radiation heating panels 118 are inside the housing 114 and face each other, and emits thermal radiation in accordance with a variable thermal output signal. A panel driver locates the radiation heating panels 118 to at least one among the plurality of positions in response to a variable view factor signal.
