  • IMAGE FORMING APPARATUS AND METHOD FOR CONTROLLING THE IMAGE FORMING APPARATUS
    Publication number: 20080136849
    Abstract: An image forming apparatus includes a recording head, a main tank, a sub tank, a negative pressure state indicator, a position detector, and a sub tank position indicator. The recording head discharges recording liquid. The main tank supplies the recording liquid. The sub tank is supplied with the recording liquid from the main tank and supplies the recording liquid to the recording head. The negative pressure state indicator is displaced according to a negative pressure state of the sub tank to indicate the negative pressure state of the sub tank. The position detector detects the displacement of the negative pressure state indicator as position information. The sub tank position indicator is detected by the position detector and indicates a position of the sub tank without being displaced according to the negative pressure state of the sub tank.
