Abstract: The disclosed print head has a two-chamber main reservoir that decouples wasted ink and purge volume in print heads. The two-chamber structure of the print head allows for varying flow of ink through the print head's internal manifolds without varying the wasted ink out of the jet stack. The main reservoir of the print head includes a recirculation chamber and an incoming ink chamber. A vacuum is applied to a vent in the recirculation chamber and a pressure can also be applied to a vent in the incoming ink chamber to cause bubbles in the jet stack to move into the recirculation chamber and be removed through the recirculation chamber vent.

Abstract: A method of mounting a substrate having an array of actuators to another substrate in a way that reduces mechanical linkage between the actuators has been developed. The method includes cutting a first plurality of channels and a second plurality of channels in a substrate on which a plurality of actuators have been formed, each actuator having two sides that are parallel to one another and longer than two other shorter parallel sides of each actuator. The first plurality of channels is cut between the longer sides of adjacent actuators and the second plurality of channels is cut between the shorter sides of adjacent actuators. The channels in the second plurality of channels have a width that is less than a width of the channels in the first plurality of channels.

Abstract: A method binds a substrate having an array of actuators to a diaphragm array in a way that reduces secondary banding in an ink jet printhead that ejects a different color ink from each row of ink jets in the printhead. The method includes cutting a plurality of horizontal channels in a substrate on which a plurality of actuators have been formed, the horizontal channels being cut between rows of actuators on the substrate, and cutting a plurality of vertical channels in the substrate on which the plurality of actuators have been formed, the vertical channels being cut between columns of actuators on the substrate, the vertical channels having a width that is less than a width of the horizontal channels.
