Nozzle assembly of an inkjet printhead
First Claim
1. A nozzle assembly for an inkjet printhead, said nozzle assembly comprising:
- an inkjet nozzle having an actuator for ejecting an ink droplet from said inkjet nozzle when a resistive element of said actuator is heated by an electrical current;
a shift register comprising a plurality of successive registers, said shift register receives input data in a first register, and shifts said input data to successive registers upon receipt of a shift signal;
a transfer register for latching data in one of the registers of said shift register;
a control gate for outputting a control pulse in response to data in said transfer register; and
a drive transistor for providing an energy pulse to said resistive element of said actuator upon receipt of said control pulse,wherein said nozzle, said shift register, said transfer register and said drive transistor are formed in a common silicon substrate and said nozzle is spaced from other nozzles sharing a common ink channel by less than 24 microns in a direction transverse to the direction of movement of a print media upon which ink is ejected.

Abstract
A nozzle assembly for an inkjet printhead is disclosed. The nozzle assembly includes an inkjet nozzle having an actuator for ejecting an ink droplet from the inkjet nozzle when a resistive element of the actuator is heated by an electrical current, a shift register comprising a plurality of successive registers, the shift register receives input data in a first register, and shifts the input data to successive registers upon receipt of a shift signal, a transfer register for latching data in one of the registers of the shift register; a control gate for outputting a control pulse in response to data in the transfer register, and a drive transistor for providing an energy pulse to the resistive element of the actuator upon receipt of the control pulse. The nozzle is spaced from other nozzles ejecting ink of a same color by less than 32 microns in a direction transverse to the direction of movement of a print media upon which ink is ejected.
