Printhead Having Ejection Nozzles Over Wide Printing Zone

Abstract

A printhead is provided having an elongate carrier, a plurality of ejection nozzle integrated circuits mounted on the carrier, and control circuitry positioned on the carrier and operatively connected to the ejection nozzle integrated circuits to control operation thereof. The mounted ejection nozzle integrated circuits have more than 150,000 ejection nozzles

1 . A printhead comprising:
 an elongate carrier;   a plurality of ejection nozzle integrated circuits mounted on the carrier; and   control circuitry positioned on the carrier and operatively connected to the ejection nozzle integrated circuits to control operation thereof,   wherein the mounted ejection nozzle integrated circuits comprise more than 150,000 ejection nozzles.   
     
     
         2 . A print assembly as claimed in  claim 1 , comprising at least 200,000 ejection nozzles. 
     
     
         3 . A print assembly as claimed in  claim 2 , comprising between 300,000 and 800,000 ejection nozzles. 
     
     
         4 . A print assembly as claimed in  claim 1 , wherein between 40 and 100 ejection nozzle integrated circuits are mounted on the carrier. 
     
     
         5 . A print assembly as claimed in  claim 1 , wherein the ejection nozzle integrated circuits are each positioned at a common angle of greater than zero degrees and less than ninety degrees along the carrier, with consecutive ends of the ejection nozzle integrated circuits overlapping.
