Abstract of the Invention This invention relates to a circuit arrangement for a temperature- dependent voltage regulating circuit for piezo-electric recording nozzles in mosaic ink-jet recording devices. For the temperature-dependent voltage supply of the piezo-electric recording nozzles in mosaic ink-jet recording devices, being operable via control circuits with an adjustable voltage, there is provided common to all of the control circuits a regulating circuit for producing a temperature-dependent output voltage, at the output of which the individual control circuits are placed in parallel; the operating voltage is individually set via adjustable resistors which are disposed at the inputs of the control circuits. The invention mitigates problems caused in the operation of such recording devices caused by significant variations in ink viscosity with temperature changes.
