Piezo bending transducer drop-on demand print head and method of actuating it |
摘要 |
Disclosed is a piezo bending transducer drop-on-demand print head and a method of actuating it. Each of the piezo bending transducers of a piezo bending transducer drop-on-demand print head is subjected to a sequence, corresponding to the desired print image, of triggering pulses each effecting a drop discharge movement and, assigned to each triggering pulse, each piezo bending transducer neighboring the piezo bending transducer triggered by the triggering pulse is subjected to a compensating pulse deflecting it. The piezo bending transducer drop-on-demand print head has a nozzle plate with nozzles arranged in series. Respectively assigned to each nozzle is a piezo bending transducer which can be subjected to a triggering pulse accompanied by a drop being discharged from the respective nozzle. There is a control device by which each of the piezo bending transducers can be subjected to triggering pulses and compensating pulses in accordance with the method of the invention.
