    摘要: A heat sink, provides a heat transfer pathway to remove heat from the rear face of a printhead substrate. The heat sink is located between the printhead substrate and the printer carriage. The heat sink may, in one embodiment, be biased to float substantially normal to the rear face of a printhead substrate using a biasing device, such as one or more springs, or a one or more spring clips. The springs, which are compressed, tend to urge the face of the heat sink against the back face of the printhead, forming an interface between the two faces. Additional force can be provided by a carriage arm, as its radius acts as a moment arm to assist in pressing the two faces together. A low thermal heat conductivity contact resistance and an improved thermal resistance to heat dissipation between the printhead substrate and the heat sink are provided by the high pressure interface resulting from the use of the springs and the radius of the carriage arm. An additional layer of heat conductive material can be provided at the interface of the heat sink and the printhead substrate. This can reduce the ability of air pockets to form between the heat sink and the printhead substrate. The additional layer is a fabric or thermal grease material which is effective to fill rough areas of surface on either the printhead substrate or the heat sink contact areas.

    摘要: A method for assembling a printhead such as an ink jet printhead can include the use of an ultrasonic bonding process to bond two or more printhead layers together. In an embodiment, an ultrasonic frequency is directed to an interface between a first layer and a second layer to generate heat at the interface. In an embodiment, the heat melts at least one of the first layer and the second layer, and the layers are cooled to cure the melted layer. In another embodiment, the heat generated using the ultrasonic frequency cures an adhesive layer between the first layer and the second layer. The ultrasonic lamination process described can result in a fluid-tight seal which requires less processing time and materials over an adhesive-based process.

    摘要: A system and method to provide pressure to de-prime a printhead. An image forming device comprises an ink reservoir that contains ink and provides the ink to a printhead. When a fault condition is detected that indicates a likelihood of a solidifying of the ink, the printhead is de-primed by applying pressure to the printhead to purge the ink from the printhead. The fault condition comprises any of a loss of power, a power-down process, or a printhead temperature being less than or equal to a threshold temperature.
