Patent ID: 8201912

Claim:
A liquid jet recording apparatus comprising: a liquid container for containing liquid; a jetting portion for jetting the liquid toward a recording medium; a liquid conduit for communicating the jetting portion with the liquid container; pressure adjusting means for adjusting the pressure of the liquid which flows through the liquid conduit; a liquid storing portion disposed in the liquid conduit between the pressure adjusting means and the jetting portion for damping pressure fluctuations of the liquid; pressure measuring means disposed in the liquid conduit between the liquid storing portion and the pressure adjusting means for measuring the pressure of the liquid which flows through the liquid conduit; and a control portion electrically connected to the pressure measuring means and the pressure adjusting means, wherein the control portion includes a setting portion for indicating the pressure fluctuations of the liquid from a position at which a measurement is made by the pressure measuring means via the liquid storing portion to the jetting portion, and, based on information set in the setting portion and a pressure value measured by the pressure measuring means, controls the pressure adjusting means so that the pressure of the liquid in the jetting portion is in a predetermined range.
