Patent attributes
A suction recovery method of an ink jet recording apparatus which can realize a suction operation, in which suction recovery performance can be improved without enlarging a size of apparatus and a number of discharge ports can be held in a good state, is provided. When a negative pressure is generated in a cap which closes discharge ports of a recording head and ink is sucked from the discharge ports, the ink is sucked by a first suction step of sucking at a first, relatively low target negative pressure, which is sufficient to allow the ink which is not suitable for recording to flow from the discharge ports, and a second suction step of sucking at a second, relatively high target negative pressure necessary for sucking bubbles in the discharge ports (particularly, near the discharge ports).
