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: A recovery system for a recording head according to the present disclosure includes a wiper, a drive mechanism, and a control portion. The control portion is able to execute a recovery operation for a recording head that includes a first ink pushing-out operation that forcibly pushes out ink, a first wiping operation that wipes away purged ink, and a second wiping operation that moves the wiper in a direction opposite to the first direction. The wiper includes a first wiping surface, a second wiping surface, and an upper surface. The upper surface is provided with a first step portion that becomes higher from a first upper end portion of the first wiping surface to a second upper end portion of the second wiping surface.

Abstract: A maintenance device maintains a head unit including an inkjet head. The maintenance device includes a cap, a supply part, an air pump, and a restriction part. The cap is attached to a nozzle surface of the inkjet head. The supply part stores a humidifying medium, generates a humidified air by passing air through the humidifying medium, and supplies the humidified air to the cap. The air pump sends air recovered from the cap to the supply part through a supply flow pass. The restriction part is provided in the supply flow pass, and generates a loss of pressure of 4σ/R or more (σ: a surface tension of the humidifying medium WM, R: an inner diameter of the supply flow pass).

Abstract: A recording head of the present disclosure includes an ink ejection surface where a plurality of ink ejection ports for ejecting ink onto a recording medium are disposed. A plurality of cleaning liquid supply ports for supplying a cleaning liquid are disposed on an upstream side with respect to the ink ejection ports in a wiping direction which is a direction in which a wiper wipes the ink ejection surface. The plurality of cleaning liquid supply ports each have a chamfer portion formed at a portion thereof that intersects a surface to be wiped by the wiper, the chamfer portion being R-shaped in section.

Abstract: An ink for ink-jet recording apparatuses, includes water, a pigment dispersion, and a super-penetrating agent and a high SP organic solvent respectively having a predetermined solubility parameter (SP value). All of differences (ΔSPs) between SP values of the neighboring organic solvents are from 0.5 to 5.0 in order of SP values thereof, and the difference of SPmax−SPmin is 12 or less in which SPmax is the highest SP value of an organic solvent among organic solvents in the high SP organic solvent and SPmin is the smallest SP value of an organic solvent among organic solvents in the super-penetrating agent.
