A liquid discharge device includes a discharge head configured to discharge a liquid on a medium conveyed, a carriage on which the liquid discharge head and a liquid cartridge are mounted configured to move in an X-axis direction, a cap disposed outside a conveying area in the X-axis direction, and configured to have contact with a nozzle surface of the discharge head on which a nozzle opens, and a control section configured to control moving of the carriage. When one of the replacement of the liquid cartridge and refill of the liquid container is performed, the control section locates the carriage at the first position where the nozzle surface is opposed to the area between the conveying area and the cap in the X-axis direction.
