CLEANING FLUID FOR LIQUID INJECTION DEVICE, LIQUID INJECTION DEVICE, AND CLEANING METHOD OF LIQUID FLOW PATH

摘要

PROBLEM TO BE SOLVED: To provide cleaning fluid for a liquid injection device capable of suppressing residue of bubbles in a liquid flow path; and to provide the liquid injection device, and a cleaning method of the liquid flow path.SOLUTION: There is provided cleaning fluid for a liquid injection device circulated into a liquid flow path (supply tube 9) provided in the liquid injection device (printer 1). The cleaning fluid for the liquid injection device contains at least a water-soluble organic solvent, a silicone-based surfactant and an acetylenediol-based surfactant. Further, the inner surface of at least a part of the liquid flow path (supply tube 9) comprises a fluorine-based material.SELECTED DRAWING: Figure 1
