Abstract

See full text

A determiner determines whether a total ink amount in an ink circulation passage calculated by an ink amount calculator is less than an ink circulation necessary amount being an amount necessary for circulation of ink in the ink circulation passage, when a liquid level detector detects that a liquid level of the ink in an ink tank is lower than a liquid level corresponding to an ink circulation standard amount being a standard for ink circulation. A controller performs ink supply amount control to supply the ink from an ink bottle to the ink tank in such an amount that the total ink amount is kept below the ink circulation standard amount, when the determiner determines that the total ink amount is less than the ink circulation necessary amount.
