摘要： An ink-jet recording apparatus includes an ink-jet head formed with an ejection face, and an ejection control board fixed to the ink-jet head. A head cover forms a container space that contains therein the ejection control board. The container space has an air inflow port and an air outflow port. An airflow generator generates an airflow that goes into the container space through the inflow port and out of the container space through the outflow port. Through the outflow port, an airflow filtered by the filter goes out of the container space across a plane including the ejection face.

The suction unit sucks the matters brushed off by the brush. The wiper has a contact face to be brought into contact with the ink ejection face to remove matters adhering to the ink ejection face. A brush moving mechanism is provided for moving the brush in parallel with the ink ejection face. A wiper moving mechanism is provided for moving the wiper in parallel with the ink ejection face. The wiper moving mechanism can move the wiper with bringing the contact face of the wiper into contact with the ink ejection face. A controller of the ink-jet recording apparatus controls the brush, the suction unit, and the wiper.
