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 with one or more valve ports, an umbilical connector, and a valve positioned between the valve plate and the umbilical connector. Ink flow between the valve plate and the umbilical connector 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.
