    摘要： In one embodiment of the invention, a structure for preventing ink shorting of conductors connected to a printhead is provided. The structure includes a layer of insulating material shaped to at least partially encapsulate the conductors on the printhead. The insulating material includes a first surface and a second surface, with each of the surfaces having an adhesive coated thereon. The adhesive includes a polymer of ethylene and glycidyl methacrylate. The adhesive may also further include an acrylic ester. Alternatively, a first adhesive may be coated onto a first surface of the insulating material or coverlayer and a second adhesive (distinct in composition from the first adhesive) may be coated onto a second surface of the insulating material or coverlayer. In another embodiment of the invention, a print cartridge for an inkjet printer, including the structure for preventing ink shorting of conductors connected to the printhead is provided.

    摘要： An ink jet printer with a reciprocating carriage having a circuit element with a number of electrical contacts and a fluid aperture. A print head is connected to the circuit element and has a body defining an ink inlet aperture adjacent the fluid aperture. The print head includes a number of conductive leads at least partially encapsulated by a portion of the print head body and connected to an electrical contact on the circuit element. The print head includes a die electrically connected to the leads, and connected to the body in communication with the ink inlet aperture. The leads may be formed from a leadframe, and the die may be at least partially encapsulated by the body.
