Liquid jet recording apparatus, liquid jet head unit, and liquid jet recording method

摘要

A liquid jet recording apparatus adjusts the pressure of liquid jetted from a jetting portion toward a recording medium. The liquid jet recording apparatus has a pressure sensor provided in a tube between a liquid storing portion and a roller tube pump. The pressure of the liquid which flows through the tube is measured, and a pressure value is sent to a control portion. The pressure value is compared with lower limit values and upper limit values stored in a definition file stored in the control portion, and a corresponding drive signal is sent to a drive portion to drive the roller tube pump in a forward or a reverse direction to adjust the pressure of the liquid in the jetting portion.
