Head Technology

Shear Mode Piezo Inkjet Print Head

Konica Minolta inkjet heads are able to handle a wide range of inks to meet the requirements of various industrial applications. The principle of shear mode piezo actuation with shared wall structure allows lower power consumption as well as a high-density nozzle array.

On-demand dot size modulation, sometimes referred to as grey-scale mode, enables the printing of high quality images and functions to increase productivity. All the development work is based on advanced computer simulation techniques that can precisely predict the droplet formation process resulting from differential ink characteristics.

The principle of ink ejection

Micro scale channels made from piezo electric material are made to contract by the application of an electric charge. As the channels contract, ink contained in the channel is forced out through the nozzle as a droplet. As the channel returns its original state, capillary action causes ink to flow into the channel making it ready to produce the next drop.

Orage indicates pressurized state. Blue indicates depressurized state.
