Abstract
An inkjet printer has an ink containing portion for containing ink, a driving portion having a nozzle for ejecting ink contained in the ink containing portion, and a first control circuit for driving and controlling the driving portion. An ink passage is disposed between the ink containing portion and the driving portion for supplying ink contained in the ink containing portion to the driving portion via an ink supply path extending from the ink containing portion through the ink passage to the driving portion. A connecting portion connects the ink passage to the printing unit. A heating portion is disposed in the ink supply path for heating the ink supplied to the driving portion. A cooling portion for cooling the ink is disposed in the ink supply path at a position closer to the driving portion than the heating portion. A temperature sensor portion for detecting the temperature of the ink supplied to the driving portion is disposed in the ink supply path at a position closer to the driving portion than the cooling portion. The heating portion, the cooling portion and the temperature sensor portion are disposed at the connecting portion. A second control circuit controls at least one of the heating portion and the cooling portion in accordance with the temperature of the ink detected by the temperature sensor portion to adjust and control the temperature of the ink before it is supplied to the driving portion.
