FIELD: printing industry.
SUBSTANCE: invention concerns fluid recording head. Fluid recording head for recording by drop ejection from multiple ejection orifices in the substrate includes multiple first ejection orifices, each for ejection of rather large volume drops; multiple second ejection orifices, each for ejection of rather small volume drops; power generation elements for drop ejection from multiple first and second ejection orifices; storage tank for fluid ejected from multiple first and second ejection orifices; at least two first fluid passages for fluid flow between fluid tank and each of the first ejection orifices; and second fluid passage for fluid flow between fluid tank and each of the second ejection orifices.
EFFECT: concordance of small and large drop ejection rates, maintenance of normal ejection mode.
