Inkjet printhead assembly having very high nozzle packing density

An inkjet printhead (40/140/240/340/440/540) assembly includes a substrate (42/142/242/542) having an ink feed slot (43/143/243/343/443/543) formed therein including a first side and second side along a vertical length of the ink feed slot. A first column of drop generators (254a) is formed along th...

More Information
Summary:An inkjet printhead (40/140/240/340/440/540) assembly includes a substrate (42/142/242/542) having an ink feed slot (43/143/243/343/443/543) formed therein including a first side and second side along a vertical length of the ink feed slot. A first column of drop generators (254a) is formed along the first side of the ink feed slot. A second column of drop generators (254b) is formed along the second side of the ink feed slot. Each drop generator (41/141/341/441/541) includes a nozzle (13/113/213/313/413/513). A nozzle packing density for nozzles in the first and second columns of drop generators including the area of the ink feed slot is at least approximately 100 nozzles per square millimeter (mm ).
