    • An air pump is driven to supply air via an air supply tube to a sub tank, by which a predetermined quantity of the air is mixed inside the sub tank via a gas-liquid separation membrane. Next, a carriage is swayed to agitate the ink by using the air mixed inside the sub tank. Then, the air pump is driven to discharge the air inside the sub tank via the gas-liquid separation membrane. In the above-described agitating motions, since the air utilized for the agitation is discharged from an ink tank after agitation processing, it is possible to prevent the air from remaining inside the ink tank to inflate, thereby adversely influencing the pressure relationship with a printing head.
    • 驱动空气泵通过空气供给管向副罐供给空气,通过该副罐将预定量的空气经由气液分离膜混入副罐内。 接下来,通过使用混合在副罐内的空气来摇动滑架来搅动墨。 然后,驱动气泵,经由气液分离膜排出副罐内的空气。 在上述搅拌运动中,由于用于搅拌的空气在搅拌处理之后从墨罐中排出,所以可以防止空气残留在墨罐内而膨胀,从而不利地影响与打印的压力关系 头。
