Abstract:
1. An elongate printhead assembly for a pagewidth printer, the printhead assembly comprising: a printed circuit board (PCB) having mounted thereon various electronic components to facilitate operation of the printer; a number of printhead integrated circuits respectively angularly disposed with respect to a longitudinal axis of the PCB; tape automated bond (TAB) film in register with a number of the printhead integrated circuits, said film configured to arrange the integrated circuits in signal communication with the electronic components; an ink distribution molding for distributing ink from an ink reservoir to the integrated circuits; and a laminated stack arranged between the ink distribution molding and the integrated circuits for ducting the ink to respective integrated circuits, the integrated circuits being mounted on the stack wherein successive integrated circuits overlap at least partially with respect to each other; wherein each integrated circuit is electronically connected to an end of the tape automated bond (TAB) film, the other end of which is maintained in electrical contact with an undersurface of the printed circuit board by means of a TAB film backing pad mounted to a plastics duct cover.
