The moveable cartridge servicing member includes at least one of a wiping element and a capping element carried by the moveable cartridge servicing member. The pocket is arranged and configured to expose nozzles of the fluid jet cartridge received by the pocket to the moveable cartridge servicing member for a servicing operation using the at least one of the wiping element and capping element.

A liquid ejecting apparatus includes a liquid ejecting head which ejects liquid from a nozzle that is disposed on a nozzle surface, a wiping member with a lengthwise shape that is able to contact the nozzle surface, a contact portion which is able to contact the opposite side from a side at which the wiping member contacts the nozzle surface, and a transport mechanism which transports the wiping member, in which the contact portion has a first contact portion which is separated from the wiping member when the wiping member is transported by the transport mechanism and which contacts the wiping member when the wiping member is caused to contact the nozzle surface, and a second contact portion which contacts the wiping member when the wiping member is transported by the transport mechanism.

A wiping method for wiping a nozzle surface of a liquid discharge head includes the step of relatively moving the liquid discharge head and a wiper impregnated with a cleaning fluid. The cleaning fluid contains a lactone compound in an amount of 5% by mass or more. The wiper includes a first layer configured to contact the nozzle surface and one or more layers other than the first layer. The first layer has a thickness of t1, the one or more layers other than the first layer have a total thickness of t2, and t1 is smaller than t2. A void ratio of the first layer is smaller than a void ratio of at least one of the one or more layers other than the first layer.

A printhead maintenance system for a printing machine having at least one printhead, the system includes a body, at least one guide track supporting the body for movement along the at least one guide track in proximity to the face of the printhead, and a drive mechanism in engagement with the body and operable to move the body along the guide track. A wiper blade is movably mounted on said body for movement between a retracted position in which the wiper blade cannot contact the face of the printhead and an operative position in which the wiper blade can contact the face of the printhead. A biasing mechanism is provided between the wiper blade and the body that is configured to bias the wiper blade to the operative position. The system includes a retraction mechanism that is operable to move the wiper blade to the retracted position upon movement of the body along the guide track.

A maintenance section configured to perform maintenance on a recording section includes a first guided section, which is guided by the guide unit, and a second guided section, which is positioned in a first movement direction, is a direction from the retreat position toward the maintenance position with respect to the first guided section, and is guided by the guide unit, when the maintenance section moves from the maintenance position in the first movement direction, the guide unit is configured to allow pivot accompanied by separation of the second guided section from the guide unit, which is pivot of the maintenance section with the first guided section as a pivot axis, and the first guided section is configured to separate from the guide unit, by moving in the first movement direction after the pivot of the maintenance section is allowed.

Provided is an inkjet recording apparatus that performs inkjet recording on a recording medium in a recording region. The inkjet recording apparatus includes a recording head that includes an ejection port surface where an ejection port for ejecting ink is provided, is the recording head being movable within a range including the recording region and a non-recording region where the recording is not performed, a cap capable of letting the ejection port in a capping state in the non-recording region, a blade that is placed between the recording region and the cap in a moving direction of the recording head, the blade being capable of wiping the ejection port of the recording head as the recording head moves from the non-recording region to the recording region, a blade moving unit capable of moving the blade up and down, and a control unit that controls the blade moving unit.

A printing apparatus includes: a recording head, discharging ink to a recording medium; a roller, having an outer circumferential surface provided for ink idly discharged from the recording head to be attached; a motor, rotating the roller in a predetermined direction; and a scraper, provided to scrape off the ink attached to the outer circumferential surface of the roller in a state in which the roller rotates in the predetermined direction. The scraper has: a recessed surface making surface contact with the outer circumferential surface of the roller; and a notch part formed at an end of the recessed surface, making line contact with the outer circumferential surface of the roller, and recessed in a substantially shape along a rotation direction of the roller and from the end of the recessed surface toward another end.

A coating device includes a head, a wiping mechanism, an arm, and a controller. The head includes a nozzle surface for discharging a coating material. The wiping mechanism wipes the nozzle surface. The arm holds the head. The controller controls movement of the head via the arm. The controller relatively moves the head with respect to the wiping mechanism to wipe the nozzle surface.

An ink jet head maintenance apparatus includes a suction member which includes a suction hole to suction ink and in which air in the suction hole is suctioned from one opening of the suction hole by a suction operation unit. The suction member includes a height adjustment surface which is adjacent to an opening surface in which the other opening of the suction hole is provided and in which an inner angle formed with the opening surface is an obtuse angle. Each position of the opening surface is able to move in a first direction including a normal direction of the opening surface in a predetermined initial state in response to external force applied to the height adjustment surface.
