INK TEMPERATURE ADJUSTMENT DEVICE AND INK CIRCULATION TYPE INKJET PRINTER HAVING THE SAME

摘要

An ink temperature adjustment device and an inkjet printer include an ink temperature adjustment path connected to a midway point on an ink supply path for supplying ink to an inkjet head configured to form an image by ejecting the ink. The ink temperature adjustment path is for adjusting a temperature of the ink supplied to the inkjet head. The ink temperature adjustment path includes an upflow path for the ink to flow upward and a downflow path for the ink to flow downward. A total cross-sectional area of the upflow path is larger than a total cross-sectional area of the downflow path.
