Abstract:
A fluid jet printer having multiple fluid ejection orifices, said printer comprising:a base carrying a housing defining a printing path, a print medium feed mechanism controllably moving print medium through said printer along said printing path, a carriage for holding a fluid jet print cartridge over said printing path, said fluid jet print cartridge including: a cartridge body defining a printing fluid chamber, and a printing fluid delivery assembly; and a printhead having a substrate, said print head receiving printing fluid from said printing fluid chamber via said printing fluid delivery assembly and controllably ejecting this printing fluid onto the print medium, said print head including: a thin-film structure carried on said substrate and including an energy dissipating clement for providing energy to said printing fluid to eject the printing fluid from the printhead; and an orifice plate with multiple fluid ejection orifices respectively separated by barrier walls having mutually coplanarized end edges which present a smooth surface for engagement contact with said thin-film structure, said orifice plate securely attached to said thin-film structure by a plurality of upstanding ribs at a peripheral portion of said orifice plate; and printing circuit that electrically couples the printing head with the printer via circuit traces connected to said energy dissipating element.
