Switching circuit for the temperature-dependent voltage regulation of piezoelectric printing nozzles in mosaic ink jet printers

摘要

The invention relates to a circuit arrangement for temperature-dependent voltage regulation for piezoelectric writing nozzles in ink mosaic writing devices. For temperature-dependent voltage supply to the peizoelectric writing nozzles in ink mosaic writing devices, which can be operated via control circuits with an adjustable voltage, a control circuit (16) common to all control circuits is provided for generating a temperature-dependent output voltage, at the output of which the individual control circuits (2) are connected in parallel; The individual division of the operating voltage takes place via the adjustable resistors (12) connected upstream of the control circuits. The invention finds application in ink mosaic writing devices.
