Abstract: A sub-tank is disposed in a flow path from a main tank to a recording head. The sub-tank includes a tank main body, a level sensor and a flow restricting part. In the tank main body, ink replenished from the main tank is contained. The level sensor detects a liquid level of the ink in the tank main body. The flow restricting part restricts flowing of the ink in an upper-and-lower direction in the tank main body. The flow path is connected to the tank main body at a position below the flow restricting part. The flow restricting part is disposed at a position below a lower limit level of the liquid level.

Abstract: An inkjet recording apparatus includes a recording head, a wiper member, a cleaning liquid supply device, a cleaning liquid flow path, and a controller. The cleaning liquid flow path includes a vertical tubular member connected to the cleaning liquid supply device and extending upward, and a horizontal tubular member connected to an upper end of the vertical tubular member and extending in a horizontal direction. The controller extrudes a cleaning liquid in at least a part of the cleaning liquid flow path from a cleaning liquid supply port before control of a cleaning operation for wiping an ink ejection surface of the recording head, thereby performing control of an air bubble release operation of the cleaning liquid flow path.

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.

Abstract: An inkjet recording apparatus includes a recording head including a plurality of nozzles for ejecting ink, a conveyor belt that has a plurality of apertures and conveys recording media one by one, a control unit, an ink receiver, and a pipe-shaped ink discharge flow path. The control unit controls drive of the recording head and the conveyor belt to perform flushing, in which the ink is ejected from the nozzle of the recording head to pass through one of the apertures, at a timing different from a timing contributing to image recording. The ink receiver is disposed to face the recording head sandwiching the conveyor belt therebetween, to receive the ink after passing through the aperture when the flushing is performed. The ink discharge flow path is connected to the ink receiver. When the flushing is performed, a predetermined amount of liquid is stored in the ink receiver.

Abstract: An ink jet recording apparatus includes a recording head, a wiper member, a cleaning liquid supply device, and a controller. The recording head includes an ink ejection surface having an ink ejection port from which ink is ejected. The cleaning liquid supply device includes a cleaning liquid supply surface having a cleaning liquid supply port from which cleaning liquid for wiping the ink ejection surface with the wiper member is supplied, and is located upstream of the ink ejection surface in a wiping direction. The controller controls a cleaning operation including squeezing out the cleaning liquid containing bubbles from the cleaning liquid supply port, and moving the wiper member carrying the cleaning liquid containing bubbles, in the wiping direction from a movement start position to an end position ahead of the ink ejection surface.

Abstract: An ink-jet recording apparatus includes an ink-jet head, a head lift, a blade, and a supply member. The ink-jet head includes a nozzle plate. The head lift moves the ink-jet head up and down. The blade performs a wiping action along a nozzle surface of the nozzle plate. The supply member is provided upstream of the nozzle plate in a forward direction of the wiping action, has a dimension in a widthwise direction intersecting the forward direction smaller than the blade, and supplies a cleaning liquid to the blade upon contact with a top edge of the blade. A ridge of the supply member where a bottom surface of the supply member meets a side surface of the supply member is provided with a bevel tilted to the bottom surface and the side surface or a curve smoothly connecting the bottom surface and the side surface.

Abstract: The inkjet recording apparatus includes a conveyance belt, a conveyance plate, a suction unit, an inkjet head, and a cleaning unit. The conveyance belt has a plurality of through holes. The suction unit causes the conveyance belt to suck the sheet. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The inkjet head includes a head main body and a head end portion adjacent to the head main body, and faces an upper surface of the conveyance plate via the conveyance belt. The cleaning unit removes ink adhering to a lower surface of the head main body. A ratio of the recessed portions per unit area in a facing region of the conveyance plate facing the head end portion is smaller than a ratio of the recessed portions per unit area in a region other than the facing region.
