Recently, demand for inkjet printers in commercial and industrial market is increasing. In the market, high speed and stable printing for a long time is needed. It is necessary to develop the ink circulation supply system which prevents ejection failure caused by inkdrying and provides the required amount of ink stably. One of the systems is a multiple-input multiple-output (MIMO) system which consists of plural pumps and plural sensors. In addition, this system is large-scale and influenced by disturbances such as temperature. For the development of the system, we have constructed a mathematical model by using system identification method. In this re port, we show the verification result of the plant model by using the real feedback system.
