Fluid ejecting apparatus and fluid filling method of fluid ejecting apparatus

A fluid ejecting apparatus comprising:

• a fluid containing portion that contains fluid;
• a fluid discharging portion that is capable of discharging the fluid;
• a flow passage forming portion that forms a fluid flow passage that extends from the fluid containing portion to the fluid discharging portion;
• a valve mechanism that is capable of opening or closing the fluid flow passage, the valve mechanism having a DC motor that supplies power for opening and closing of the fluid flow passage;
• and
• a motor driving circuit that is configured to be used as a stepping motor and that drives the DC motor, the motor driving circuit being capable of applying a predetermined electric current to the DC motor through a terminal to cause the DC motor to open or close the valve mechanism;
• wherein the fluid ejecting apparatus is placed in an initial state before an initial use of the fluid ejecting apparatus wherein the fluid is contained in the fluid containing portion, and at least a portion of the fluid flow passage from a position of the fluid containing portion to the position of the valve mechanism is filled with the fluid and the fluid flow passage is closed by the valve mechanism,
• wherein before initially using the fluid electing apparatus, after the fluid is filled in the fluid containing portion, the fluid flow passage is closed by the valve mechanism and the DC motor is connected to a terminal of the motor driving circuit.
