ABSTRACT:
Provided is an ink reservoir assembly for a pagewidth printhead. The reservoir assembly includes a core element defining discrete ink reservoirs with fluid passages leading towards a recess for receiving a molding operatively distributing said fluid to a printhead integrated circuit. The reservoir assembly also includes an outer shell comprised of a hot rolled tri-layer laminate of a first metal layer sandwiched between two second metal layers so that an effective coefficient of thermal expansion of said shell is substantially equal to that of a material comprising the integrated circuit.
