摘要： An ink jet recording apparatus includes an ink container in which ink to be used to perform printing on a print target is stored, a nozzle which is connected to the ink container and from which pressurized and supplied ink is jetted, charging electrodes that charge ink particles jetted from the nozzle with electricity, deflecting electrodes that polarize the ink particles charged with electricity by the charging electrodes, a gutter that recovers ink not used for printing, a solvent container in which a solvent is stored, and a liquid nozzle which is connected to the solvent container and from which a pressurized and supplied solvent is jetted. The liquid nozzle includes a liquid flow passage portion that extends from the nozzle in a direction of the gutter, and a liquid jet hole that is formed at an angle allowing the pressurized and supplied solvent to hit the nozzle through the liquid flow passage portion.

摘要： An inkjet printing device allows separation of ink solvent liquefied in an exhaust passage from exhaust gas, and prevents the separated exhaust gas from contaminating the inside of the print head. When ink fed from a container is jetted from a printing nozzle, ink that has not been used for the printing is drawn by a gutter along with air and collected in the container. Air mixed with the ink solvent and collected is discharged as exhaust gas into an exhaust passage from the container. The ink solvent that has been liquefied in the exhaust passage is separated from the gas by retaining the liquid using capillary action in a gas-liquid separator, and the separated liquefied ink solvent is collected. The trace amount of the ink solvent leaking on the exhaust side of the gas-liquid separator is prevented from dripping into the print head by a drip prevention unit.

摘要： An inkjet recording device and a method for controlling an inkjet recording device are provided. A heating device that heats the ink to be supplied to a nozzle immediately ahead of the nozzle, a thermometer that detects a temperature of the ink inside the heating device or after heating, a viscometer that detects a viscosity of the ink in a main ink container are provided. The heating device is driven using a detection value of the thermometer to control the temperature of the ink such that the viscosity reaches an ink viscosity which enables normal printing, and when the viscosity of the ink is out of a range which enables printing, the solvent or the replenishment ink is supplied to the main ink container using a detection value of the viscometer such that the viscosity reaches the range which enables normal printing.

摘要： A gas-liquid separator includes a casing with a cylindrical chamber inside, a gas-liquid 2-phase inlet pipe which is attached to a wall of the casing and connected to the chamber, a gas outlet pipe for discharging the gas of a gas-liquid mixture flowing into the chamber, and the gas-liquid 2-phase outlet pipe for discharging the liquid as a most part of the gas-liquid mixture flowing into the chamber. A gap is formed around the gas-liquid outlet pipe in the chamber for separating the mixture into liquid and gas using the surface tension and suction force. The gas-liquid separator is installed in the inkjet recording apparatus, especially in the print head. The print head is filled with the solvent gas so as to be suctioned from the gutter to reduce the solvent consumption.
