Abstract
An inkjet recording device includes: a head; an ink tank which is connected with the head through a supply channel and a collection channel; a deaeration module which is provided on a side of the supply channel; a main tank; and a supply control unit which controls supply and collection of the ink, where: a supplement flow rate from the main tank to the ink tank is assumed as L1 (ml/sec), a consumption flow rate of ejection from the head is assumed as L2 (ml/sec), and, in the case of L1<L2, print time limit n is calculated by equation: n≦(ΔT/L2)+[T/(L2−L1)]; and, when printing does not end within the print time limit n, the printing is interrupted and the ink is deaerated by circulating the ink.
