Claims8
A printhead assembly for a pagewidth drop on demand ink jet printer, comprising:
- an array of printhead modules extending substantially across said pagewidth,
- a flexible printed circuit board carrying data and power to said modules, the flexible printed circuit board also extending substantially across said pagewidth,
- a pair of busbars electrically connected to the flexible printed circuit board and carrying power thereto, the busbars also extending substantially across said pagewidth, wherein said printhead modules are fixed to an elongate channel and wherein an elastomeric ink delivery extrusion is situated between the modules and the channel and wherein the flexible printed circuit board is sandwiched between the elastomeric ink delivery extrusion and the channel and extends around one edge of the extrusion to carry power and data to the printhead modules.
