摘要： A maintenance and recovery device of a liquid droplet discharge apparatus improves a performance of discharging droplets of a liquid having a high-viscosity. A liquid droplet discharge head (34) discharges droplets of a recording liquid from a nozzle. A suction cap member (92a) caps a nozzle plane of the liquid droplet discharge head (34). An inclined surface (191) provides a slope toward an evacuation port (194) on a bottom of the suction cap member (92a). The inclined surface (191) forms an inclination angle with respect to a horizontal plane. The inclined surface is formed of a material having a contact angle with respect to the recording liquid. A sum of the inclination angle and the contact angle is equal to or larger than 70 degrees.

摘要： A method for supplying a liquid from a liquid tank to a head tank fixed to a liquid-jet head utilizing a liquid supply device in a liquid-jet apparatus is disclosed. The method includes jetting the liquid droplets from the liquid-jet head while maintaining a meniscus pressure of the liquid-jet head within a predetermined range; detecting the meniscus pressure of the liquid-jet head; carrying out, when the detected meniscus pressure is lower than the predetermined range, a first liquid supply operation such that the detected meniscus pressure of the liquid-jet head being lower than the predetermined range is restored to the predetermined range; and carrying out, while the first liquid supply operation is not being carried out, a second liquid supply operation such that the liquid is supplied to the head tank in an amount less than a liquid-jetted amount computed based on a liquid-jet signal.
