PURPOSE:To obtain the captioned device which does not suck the air into a recording head and assures recovery of printing by feeding ink into a recording head after filling ink above a prearranged quantitative level inside an ink reservior connected to a recording head. CONSTITUTION:If a piston 112 making up a liquid introduction means 106 is de- pressed, first a remaining air inside a liquid reservoir 103 is sucked and a liquid is injected into the liquid reservoir 103 from a liquid reservoir 101. The liquid is sucked in through a recording head 104 after the rear end of a feed channel 107 is immersed in the liquid, air entrainment into a liquid channel inside the recording head is prevented. In addition, the pressurization action of the piston 112 is repeated according to necessity. This action results in the rising of the liquid inside the liquid reservoir 103 upto a suction port 118. However, the liquid also will be sucked in through the suction port 118, so that the liquid level inside the liquid reservoir 103 is maintained upto the height of the suction port 118. |
