A maintenance apparatus that removes bubbles from a nozzle is provided in a printer that includes a recording head having a nozzle capable of ejecting ink from a nozzle opening formed in a nozzle formation surface. The maintenance apparatus includes: a pressurizing pump that pressurizes the ink in the nozzle in a direction in which the ink is discharged from the nozzle opening; and a contact member having an upper surface that makes contact with the nozzle formation surface so as to cover the nozzle opening, and that has, formed therein, a flow channel whose pressure loss is greater than that of the nozzle and that allows air to pass through from the side of the upper surface. The ink within the nozzle is pressurized by the pressurizing pump in a state in which the contact member is in contact with the nozzle formation surface.
A maintenance apparatus, provided in a liquid ejecting apparatus including a liquid ejecting head having a nozzle capable of ejecting a liquid from a nozzle opening formed in a nozzle formation surface, that removes bubbles from within the nozzle, the maintenance apparatus comprising:
A maintenance method for a liquid ejecting apparatus that includes a liquid ejecting head having a nozzle capable of ejecting a liquid from a nozzle opening formed in a nozzle formation surface and that employs a maintenance apparatus, the maintenance apparatus including a pressurizing unit that pressurizes the liquid in the nozzle of the liquid ejecting head in a direction in which the liquid is discharged from the nozzle opening and a flow channel formation member having a flow channel whose pressure loss is greater than the pressure loss of the nozzle and that allows air to pass through but regulates the passage of the liquid, and the method comprising:
