Abstract: A head cleaning mechanism of the disclosure includes a recording head and a wiper. The recording head includes an ink ejection surface in which an ink ejection area with a plurality of ink ejection ports opened therein is provided. The wiper wipes the ink ejection surface in a specified direction. The recording head includes an inclined surface placed on an upstream side of the ink ejection surface in a wiping direction that is a direction in which the wiper wipes the ink ejection surface, the inclined surface being inclined downward toward a downstream side of the wiping direction. A plurality of cleaning liquid supply ports for supplying cleaning liquid are provided on a wiping-direction upstream side of a position in the inclined surface with which the wiper makes contact during wiping operation.

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.

Abstract: In an inkjet recording apparatus, a recording head has an ink ejection port through which ink is ejected, a cleaning liquid supplying portion has a cleaning liquid supply port through which cleaning liquid for cleaning an ink ejection surface having the ink ejection port, is supplied, and a cleaning member cleans the ink ejection surface by the cleaning liquid by moving while in contact with the ink ejection surface. The cleaning liquid supplying portion includes a main body portion and a protruding portion. The main body portion is disposed on an upstream side of the recording head in a moving direction of the cleaning member. The protruding portion protrudes from the main body portion toward a downstream in the moving direction, and covers, from below, lower ends of side surfaces of the recording head and the main body portion that face each other in the moving direction.

Abstract: A recording head recovery system includes a recording head and a wiper. The recording head includes an ink ejection surface provided with an ink ejection region in which ink ejection ports are formed. The recording head is disposed on a wiping direction upstream side of the ink ejection region, and a cleaning liquid supply region in which cleaning liquid supply ports for supplying cleaning liquid are formed. The pressure contact angle of the tip of the wiper to the ink ejection surface is decreased after the wiper passes the cleaning liquid supply region before reaching the ink ejection region.
