Abstract

PURPOSE:To prevent a plugging in an ink flow channel by circulating a diluent and cleaning an ink flow channel during nonrecording time and adjusting the concentration and viscosity of ink with a diluent during recording time. CONSTITUTION:A high-level detection signal Sb from a recording state detection means 18 is output to a control circuit 19 and this circuit 19, based on the said signal Sb and a detection signal Sa from a concentration/viscosity detector 17 provided inside a subtank 5, outputs control signals Sc, Sd controlling the operation of an ink valve 3 and a diluent valve 4 respectively during recording time. Ink or a diluent is supplied into a tank from tanks 1, 2 for adjustment of the concentration/viscosity of ink and then ink is caused to spurt from an ink gun 10. While during nonrecording time, low-level signal Sb is outputted to the circuit 19 from the detection means 18, outputting a control signal Sd to open the valve 4, so that a diluent in a tank 2 is supplied to a tank 5 and a diluent is run through a pipe 9 for cleaning an ink flow channel and a gun 10.
