Abstract: A liquid jet recorder which includes at least one jet nozzle which is connected to a pressure medium conduit for the ejection of an electrically-conductive recording liquid onto a recording carrier, and which includes at least one control electrode connected to a signal source for modulation of the liquid jet in the context of carrying out spot or point wise recording. The liquid jet recorder of the above-mentioned type, which in a simple manner facilitates that the intensity of a recording color may be controlled within a predetermined range of accuracy.

Abstract: A liquid jet recorder including at least one nozzle which is connected to a pressure medium conduit for ejection of an electrically-conductive recording liquid onto a recording carrier, with at least one control electrode connected to a signal source for modulation of the liquid jet, and means for generating a relative motion between the nozzle and the recording carrier in two mutually perpendicular directions in the context of providing a linewise image recording.

Abstract: A liquid jet recorder having at least one jet nozzle which is connected to a pressure means conduit for the ejection of an electrically-conductive recording liquid onto a recording carrier; having at least one control electrode encompassing the liquid jet which is disintegrating into drops, which is formed of porous material which communicates with a suction conduit for the recording liquid; and a signal source adapted to be switched between the control electrode and the liquid jet for charging of the drops so that the latter mutually repel each other and disintegrate into a vapor cloud adapted to be aspirated into the control electrode. The recorder includes a suction pump, including circuitry which will activate the suction pump prior to the commencement of a recording. In the liquid jet recorder, any possible residues of the recording liquid adhering to the control electrode are aspirated prior to commencement of a recording.
