    Abstract: Print head jet stack heating and temperature measurement systems and methods are disclosed that both heat the jet stack and determine a temperature of the jet stack. The heating and temperature determination are performed by a flex circuit that includes multiple layers. One of the layers heats the jet stack and another one of the layers provides data that determines the temperature of the jet stack. The heating layer and the temperature sensing layer are separated by an insulative material in the flex circuit. The temperature of the jet stack can be sent to a print head controller that then determines whether to increase or decrease the temperature of the jet stack.

    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 print head has an ink reservoir to hold ink, the reservoir having protrusions, an external manifold coupled to the ink reservoir, the ink manifold having channels on a first surface that match the protrusions, and an adhesive in the channels to contact the protrusions. A method of assembling a print head includes mounting a jet stack to a flat plate of a merge fixture, dispensing adhesive on an external manifold attached to the jet stack, placing a reservoir in the merge fixture above the external manifold such that the reservoir does not contact the adhesive, attaching an upper plate to the reservoir to set a depth, pressing the reservoir into the adhesive, and curing the adhesive.
