Control element for printed drop density reconfiguration
Abstract:
A method of printing includes providing a printhead including a jet control element including a continuous heater element positioned to surround a nozzle. A plurality of three or more electrical contacts is in electrical communication with the continuous heater element. The plurality of three or more electrical contacts define a plurality of three or more continuous heater element portions that are actuatable with sufficient independence so as to control jet steering. The number of the continuous heater element portions equals the number of electrical contacts. A liquid is provided under a pressure sufficient to eject a jet of liquid through the nozzle. A waveform is applied to at least one of the plurality of three or more electrical contacts using a controller to affect at least one of the plurality of independently actuatable continuous heater element portions to control the jet of liquid.
