The apparatus includes a tube pump for discharging a fluid in a capping means sealing a nozzle forming face of a liquid ejecting head, having a roller member rolling on an inner periphery of a curved part of a tube member by pressing and deforming the curved part and a leak point, a phase detection means for detecting a phase of a rotational motion of the roller member, and a control means for controlling the operation of the tube pump. The control means has a function for stopping the roller member at a predetermined position based on information on the phase of the rotational motion of the roller member detected by the phase detection means. The suction amount of the liquid suction operation by the tube pump is prevented from variation.
