Abstract
A technique allows sucking ink adhering to the lower surface of a head and preventing the ink from being sucked out from the inside of nozzles of the head. The printer includes a head that ejects ink and a maintenance unit that performs maintenance of the head. The head has a lower surface that includes a nozzle face provided with a plurality of nozzles and side faces located adjacent to the nozzle face. The maintenance unit includes a cleaning block that sucks the ink from the lower surface of the head. The cleaning block has an upper surface that includes a first region that faces the nozzle face and second regions that face the side faces. The suction force acting on the first region is smaller than the suction force acting on the second regions. This reduces the possibility that the ink is sucked out from the inside of the nozzles of the head.
