Abstract:
1. A method of supplying ink to ink ejection nozzles on a printhead for an inkjet printer with a print engine controller for controlling the printhead operation, the method comprising the steps of: providing a printhead integrated circuit having an array of the ink ejection nozzles formed on a substrate; providing circuitry for electrical connection to the print engine controller; providing a support member for supporting the printhead integrated circuit and the circuitry within the printer; providing a thermoplastic polymer sealing film; securing the polymer film to a mounting surface of the support member by applying heat and pressure thereto for a predetermined time; mounting the printhead integrated circuit and the circuitry to the mounting surface via the polymer film; and, electrically connecting the circuitry to the printhead integrated circuit; wherein, a plurality of ink feed channels extend over the mounting surface for establishing fluid communication with at least one ink storage compartment; and, the polymer film is attached to the support member between the ink feed channels and the printhead integrated circuits, the polymer film having an array of apertures such that the ejection nozzles are in fluid communication with the ink feed channels.
