Abstract
Provided is a method of controlling a CMOS-implemented control circuit for operating a micro-electromechanical inkjet nozzle arrangement of a printer. The circuit includes a plurality of sequential shift registers, a transfer register, a firing control gate and a drive transistor. The method includes the steps of transferring data from the shift register to the transfer register, latching the data in said transfer register, activating the firing control gate to arrange a heater element of the nozzle arrangement in electrical communication with a current source to facilitate ink ejection via thermal cavitation of ink in the nozzle.
Claims7
A method of controlling a CMOS-implemented control circuit for operating a micro-electromechanical ink jet nozzle arrangement of a printer, said circuit comprising a plurality of sequential shift registers, a transfer register, a firing control gate and a drive transistor, wherein the method comprises the steps of:
- transferring data from the shift register to the transfer register;
- latching the data in said transfer register;
- and
- activating the firing control gate to arrange a heater element of the nozzle arrangement in electrical communication with a current source to facilitate ink ejection via thermal bubble formation of ink in the nozzle.
