  • Publication number: 20190240977
    Abstract: The present teachings describe a printhead assembly. The printhead assembly includes a first plate and a second plate stacked together. The printhead assembly includes a first adhesive between the first plate and the second plate for bonding the plates together. The printhead assembly includes a second adhesive surrounding an outer edge of the first adhesive wherein the second adhesive has an oxygen migration rate lower than an oxygen migration rate of the first adhesive. An oxygen sensitive component is contained within the outer edge of the first adhesive.

  • Patent number: 10328691
    Abstract: A print head has a jet stack, a jet stack heating and temperature measuring element thermally connected to the jet stack, the jet stack heating and temperature measuring element including: a first, etched copper layer having heat spreading characteristics and including a resistive heat source electrically connected in series to a voltage source and a switch; an electrically insulative on a back side of the first copper layer; and a second, etched copper layer on a side of the electrically insulative layer opposite the first copper layer, the second copper layer having a temperature sensing element to sense a temperature of the print head without a thermistor, the temperature sensing element connected in series with a voltage source and a transistor. A print head may use a thermistor but the heat spreading layer eliminates the need for a heat sink to attach to the print head.

  • Patent number: 9931840
    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.

  • Publication number: 20160136951
    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.

  • Patent number: 9039141
    Abstract: A fluidic structure has a first chamber having a connection to a fluid reservoir and a connection to an array of apertures, the chamber forming a flow path between the fluid reservoir and the array of apertures, a second chamber having a connection to at least one vent connected to an atmosphere external to the fluidic structure, and at least one path between the first chamber and the second chamber.

  • Patent number: 9004661
    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.
