Abstract
A print assembly for a wide format pagewidth inkjet printer includes an elongate carrier that is mountable on a support structure of the printer and is positioned an operative distance from a platen of the printer. A number of printhead chips are mounted on the carrier. The printhead chips are provided in a number and configuration such that the printhead chips define a printing zone between the carrier and the platen, the printing zone having a length of at least 36 inches (914 mm). Each printhead chip is of the type that incorporates a plurality of nozzle arrangements, each nozzle arrangement being in the form of a micro electromechanical system to achieve the ejection of ink from the nozzle arrangement. Control circuitry is positioned on the carrier and is operatively connected to the printhead chips to control operation of the printhead chips.
