Abstract:
A method of controlling nozzle camber angle in an ink-jet printhead, comprising the steps of:providing an orifice plate, said orifice plate including a plurality of ink emitting orifices;providing a plurality of ink drop generators, each one of said ink drop generators having a center region generally aligned with a respective ink drop emitting orifice;providing a thin film substrate disposed under said orifice plate and adjacent each one of said plurality of ink drop generators, said substrate including a plurality of thin film layers;determining the relative angle between one of said ink emitting orifices and its respective ink drop generator center region to ascertain nozzle camber angle; andforming an insert in said thin film substrate for helping to align said ink emitting orifice with its respective ink drop generator center region thereby to control nozzle camber angle in said printhead.
