ABSTRACT:
The apparatus has valve units capable of blocking respectively liquid feed paths connecting a liquid storage unit and a liquid jet head, and control unit. The control unit has a function for executing a pressure reduction step of putting the valve unit corresponding to the kind of liquid to be cleaned into an open state, simultaneously putting the other valve units into a closed state, exhausting a closed space formed by a capping unit with the head and generating a negative pressure state therein, a totally-closing step of switching the valve unit in the open state to the closed state and putting all the valve units into the closed state almost simultaneously with stopping exhausting or immediately before it, and a totally-opening step of putting all the valve units into the open state after a lapse of a predetermined time. Cleaning is executed only for a specific kind of liquid free of obstacles.
