The paste dispensing apparatus includes a closable passage from the reservoir to the receptacle. The closable passage is changeable between an open state and a closed state. In the open state, the receptacle is fluidly coupled to the reservoir so that paste can pass from the reservoir to the receptacle. In the closed state, the receptacle is fluidly decoupled from the reservoir so that the paste is prevented from passing from the reservoir to the receptacle. The paste dispensing apparatus includes a pusher for pushing paste out of the receptacle. The method includes transferring a first volume of paste from the reservoir to the receptacle while the closable passage is in the open state. The method includes, after the transferring, changing the closable passage from the open state to the closed state. The method includes, after the changing, performing a first discharging operation by the pusher to discharge a first amount of paste from the receptacle while the closable passage is in the closed state.
