Maintenance device, fluid ejecting apparatus and maintenance method

摘要

A printer includes a fluid ejecting head having a plurality of nozzles, an ink supply channel and a maintenance device. The maintenance device includes a pressure regulating mechanism configured to reduce the pressures in the interiors of the ink supply channels at a position of pressure reduction, and a tight cap being brought into abutment with the fluid ejecting head so that the nozzle openings of the nozzles which receives a supply of ink through flow channels which are subject to relatively small pressure losses first by priority according to the magnitudes of the pressure losses in the respective flow channels extending from the position of pressure reduction to the respective nozzles.

1. A maintenance device for a fluid ejecting apparatus including a fluid ejecting head provided with a plurality of nozzles configured to eject fluid and fluid supply flow channels configured to supply the fluid toward a downstream side, which corresponds to the side of the fluid ejecting head, comprising:
a pressure regulating mechanism configured to reduce pressures in the fluid supply flow channels at a position of pressure reduction on an upstream side of the fluid ejecting head; and an abutting member configured to contact nozzle openings of the fluid ejecting head after the pressure reduction by the pressure regulating mechanism has started, so that the nozzle openings of the nozzles which receive a supply of the fluid through the flow channels which are subject to relatively small pressure losses are closed by priority according to the magnitudes of the pressure losses in the respective flow channels extending from the position of pressure reduction to the respective nozzles.
