Abstract
A liquid ejecting apparatus includes a recording head that ejects an ink from a plurality of nozzles, a liquid supply passage and a reservoir that supply the ink from an upstream side toward a downstream side, a maintenance pump that is able to suck and discharge the ink from and to the liquid supply passage, a filter that clarify the ink in the reservoir, and a control unit that performs a recovery process of the nozzles by controlling an operation of the pump, wherein the control unit causes the maintenance pump to perform a sucking operation to suck the ink, and then causes the pump to perform a discharging operation to discharge the ink, thereby supplying the ink clarified by the filter to the nozzle side.
