Abstract

A modular pagewidth printhead assembly includes a plurality of printhead modules, a fluid delivery structure and a flexible printed circuit board. Each printhead module includes a printhead integrated circuit with a plurality of micro-electromechanical nozzle arrangements, and a fluid distribution assembly of liquid crystal polymer micromoldings defining a plurality of discrete fluid paths when joined for supplying discrete fluids to the nozzle arrangements. The fluid delivery structure is configured to receive the printhead modules and to supply said modules with discrete fluids. The flexible printed circuit board is sandwiched between the supply structure and the printhead modules, and is bonded to the supply structure to keep it in place. The circuit board extends around one edge of the supply structure for carrying data and power to said modules. The fluid distribution assembly includes at least one elastomeric pad to take up tolerance when the relevant module is located on the supply structure.
