ABSTRACT:
An ink jet apparatus has a sucking device for sucking ink from a cap, and this sucking device includes a sucking space formed by a cylinder and piston adapted to the cylinder, wherein an internal pressure variation in the sucking space varies according to the mutual relation of the cylinder and piston. The sucking device has a suction opening for transmitting the internal pressure variation in the sucking space to a cap for covering an ink discharge opening of a recording head. A controller regulates the sucking means so that a stroke of the piston in the cylinder of an idle suction when the suction is performed in a state where the cap is opened to atmosphere is smaller than that of a true suction when the suction is performed in a state where the cap is closed to the atmosphere. The idle suction starts from a start point in which the piston and cylinder are disposed relative to each other such that the piston shuts the suction opening just after a start of the idle suction and advances toward a lower dead point of the cylinder.
