Abstract
Air from a pressurizing pump is supplied to a plurality of ink jet heads through an air tank and a plurality of ink tanks, and head inner pressures of the respective ink jet heads are raised. Accordingly, ink liquids are discharged from the respective ink jet heads. Thereafter, the desired ink tank among the respective ink tanks is allowed to communicate with the air tank. Moreover, the desired ink tank and at least one or more air tanks are opened to the atmosphere. In consequence, pressure in the desired ink tank is averaged.
