    Abstract: PROBLEM TO BE SOLVED: To provide a maintenance method of ink jet recorder, and an ink jet recorder using it, in which a stabilized recording state can be sustained well for a long term without increasing the size or the cost of the recorder even if an insoluble component is produced when the ink jet recorder is not used for a long term. SOLUTION: The maintenance method of an ink jet recorder employing an ink set of cyan, yellow and magenta inks where an insoluble component is produced when a component evaporated from at least one ink is dissolved into other ink comprises a step for discharging the insoluble component at least partially or entirely independently from an external signal.

    Abstract: PROBLEM TO BE SOLVED: To resultantly improve a recording speed by altering a supply mode of an ink supply means by a control means in response to an operating state of a recorder at a supply time detected by a detecting means at an ink supply time to an ink tank. SOLUTION: A control mans 25 of the inside of a cover 4 controls a recording head 20a or the like based on image data, controls to additionally receive a detection signal of a rear end of a medium S to be recorded of a photosensor 12 or a position or a suction passage switching mechanism, to count the number of droplets of discharged inks of respective colors from the head 20a, to complete recording of the medium S during recording when one arrives at a predetermined number, and to start an ink supplying operation from a supplementary tank 22 to a storage tank 20 when the medium S is discharged. Further, an ink supply mode is controlled to be changed to an ink amount capable of recording in a lowest residual tank or a full tank by the supply means in response to the operating state of the recorder at the ink supply time.
