ABSTRACT:
In an inkjet printer where an ink recycling path for recycling ink is formed by connecting among an ink head, an upstream tank, and a downstream tank, the inkjet printer includes a temperature detecting unit that detects a temperature of recycling ink, a temperature changing unit that is installed in the ink recycled path and changes the temperature of the recycling ink so that the temperature of the recycling ink reaches a predetermined temperature, and an ink recycling amount changing unit that is installed at the upstream tank and changes an ink recycling amount according to the change in temperature of the recycling ink. Time required to make the temperature of the recycling ink reach the predetermined temperature can be shortened.
