Abstract
PURPOSE:To maintain the stable pressure at a lower cost by controlling the valve mechanism provided in the ink supply system in accordance with the changes in the number of liquid drops jetted from the nozzle. CONSTITUTION:The printing command 30 to the ink jet head designed to perform recording by jetting through each nozzle 3 by the head control circuit 10 is introduced to the pressure stabilizing circuit 20 to count the number of dots of printing command 30. When the count of the total dot number counter circuit 11 exceeds the set value, the valve 2 provided at a part of the ink supply system 100 is opened temporarily by the valve control circuit 12. The total dot number counter circuit 11 is reset each time the valve is opened, so that the pressure between the valve 2 and the nozzle 3 can be maintained within a certain range.
