The dynamics of the piezo inkjet printhead operation
The operation of a piezo inkjet printhead involves a chain of processes in many physical domains at different length scales. The final goal is the formation of droplets of all kinds of fluids with any desired volume, velocity, and a reliability as high as possible. The physics behind the chain of processes comprise the two-way coupling from the electrical to the mechanical domain through the pi...
متن کاملAir entrapment in piezo-driven inkjet printheads
The stability of inkjet printers is a major requirement for high-quality-printing. However, in piezo-driven inkjet printheads, air entrapment can lead to malfunctioning of the jet formation. The piezoactuator is employed to actively monitor the channel acoustics and to identify distortions at an early stage. Modifications of the response of the piezoactuator indicate entrapped air bubbles and t...
متن کاملModel-Free Feedforward Control of Inkjet Printhead’
Inkjet printers are non-impact printers which print text and images by spraying tiny droplets of liquid ink onto paper. Besides the well known small inkjet printers for home and office, there is a market for professional inkjet printers. Inkjet printers are used to form conductive traces for cir cuits, and color filters in LCD and plasma displays. That makes the printing quality is an important...
متن کاملDevelopment of Inkjet Nozzle Driven by Double Piezo Actuators
An inkjet nozzle with double piezo transducers has been designed, which is different from conventional inkjet nozzles. The body of the nozzle which is fabricated by precision machining techniques is made from transparent acrylic material to visualize the flow inside the nozzle. The piezoelectric actuators are activated by a voltage amplifier which generates high-voltage bipolar waveforms. The k...
