Abstract: At least one printing fluid of a printing fluid supply system of a printing press is changed. A printing unit of the printing press includes a print head. At least a first printing fluid or second printing fluid is selectively conducted from at least one supply unit to the print head. The at least one supply unit includes a reservoir of the first printing fluid and a reservoir of the second printing fluid. The at least one supply unit further includes an intermediate tank of the first printing fluid and an intermediate tank of the second printing fluid arranged between the reservoirs and the print head in the flow direction of printing fluid. The first and second printing fluids are conducted from their respective intermediate tanks to the print head, and there is no return of the printing fluids from the intermediate tanks to the respective reservoirs.

Abstract: A novel inkjet recording device that allows occurrence of scattering to be suppressed without limiting the size of a printed character (font size) is provided. The novel inkjet recording device is so configured that a deflection positive electrode, a deflection negative electrode, or both the deflection positive electrode and the deflection negative electrode constituting a print head can be moved along a direction of ejection of ink droplets in correspondence with the size of a printed character.

Abstract: A transportation portion includes an apparatus body, a cover, first and second path formation portions, and a movement portion. The apparatus body has a transportation path including a downward path and an upward path having portions located at the same level in the Z direction. The cover covers and uncovers the transportation path. The first path formation portion is movable to a first position and to a second position. The second path formation portion defines the upward path and defines the downward path with the first path formation portion. The movement portion moves the first path formation portion in response to opening or closing of the cover. The first path formation portion is positioned in a movement area during a closed state. The movement portion moves the first path formation portion to the second position when the cover is opened and to the first position when the cover is closed.

Abstract: Provided is an ink-replacement method for an inkjet recording apparatus that includes a recording head having an ink ejection surface on which a plurality of nozzles for ejecting ink onto a recording medium is arranged, a sub-tank for temporarily retaining the ink supplied from an ink container, and an ink flow path along which the ink circulates from and to the sub-tank by passing through the recording head. In replacing a first ink present in the ink flow path with a second ink to be newly supplied to the recording head via the ink flow path, when the second ink is caused to flow from the sub-tank into the ink flow path, pulsation is generated in the ink flow path.
