Abstract:
1. An inkjet printer comprising: an ink head that performs printing by discharging ink; an upstream tank that supplies ink to the ink head; and, a downstream tank that receives ink not discharged from the ink head, wherein an ink recycling path is formed to recycle ink through a channel connecting the ink head, the upstream tank, and the downstream tank, the inkjet printer further comprising: a temperature detecting unit that detects a temperature of the ink recycling through the ink recycling path; a temperature changing unit that is installed in the ink recycling path and changes the temperature of the recycling ink so that the temperature of the recycling ink detected by the temperature detecting unit becomes a predetermined temperature; and ink recycling amount changing units that are installed at the upstream tank and/or the downstream tank and change an ink recycling amount according to a change in temperature of the recycling ink by the temperature changing unit.
