Wide Format Pagewidth Inkjet Printer

摘要

A print assembly ( 14 ) for a wide format pagewidth inkjet printer ( 10 ) includes an elongate carrier ( 187 ) that is mountable on a support structure ( 12 ) of the printer and is positioned an operative distance from a platen ( 106 ) of the printer ( 10 ). A number of printhead chips ( 186 ) are provided in a number and configuration such that the printhead chips define a printing zone ( 120 ) between the carrier ( 187 ) and the platen ( 106 ), the printing zone ( 120 ) having a length of at least 36 inches (914 mm). Each printhead chip ( 186 ) is of the type that incorporates a plurality of nozzle arrangements ( 210 ) and being in the form of a micro electromechanical system to achieve the ejection of ink from the nozzle arrangement ( 210 ). Control circuitry ( 190 ) is positioned on the carrier ( 187 ) and is operatively connected to the printhead chips ( 186 ) to control operation of the printhead chips ( 186 ).
