Abstract: PURPOSE:To keep a discharge state of a recording head optimum by a method wherein a means in which ink is discharged from a liquid path and a liquid chamber via an ink discharge opening to carry out discharge-recovering process, a means in which a bubble is generated in the liquid chamber by a superheating means, etc., are provided. CONSTITUTION:At a step S 100, whether at least 72 hours have elapsed or not after suction of the last time is discriminated by a time-counting means of a recorder. When at least 72 hours have elapsed, the procedure advances to a step S101, and a sub heater in the liquid chamber is driven to generate a bubble in the liquid chamber. By suction after bubbling in sucking operation at a step S102, suction recovery becomes possible by an ink consumption about 60% less than a sucked amount when the liquid chamber filled with ink. At a step S103, wiping for removing an ink liquid drop and dust which are stuck to a discharge opening surface of a recording head is carried out. At a step S104, preliminary discharge for removing the dust or the like entered the discharge opening by wiping is carried out.
