Abstract
A method for cleaning a fluid ejecting apparatus is provided. The fluid ejecting apparatus includes a fluid ejecting head that has a plurality of nozzle openings through which fluid is ejected, a fluid supply passage through which the fluid is supplied toward the fluid ejecting head, an open/close valve that is provided on the fluid supply passage, and a pressure reduction mechanism that generates negative pressure in a space outside the nozzle openings. The cleaning method includes a valve-closing operation of putting the open/close valve into a closed state and a pressure reduction operation of generating negative pressure in the space by using the pressure reduction mechanism after the valve-closing operation to cause the fluid to bulge outward at the nozzle openings.
