Abstract:
Provided are a liquid jetting device, a liquid jetting head cleaning device, and a liquid jetting head cleaning method, in which a nozzle surface is cleaned without a liquid infiltrating into a gap of a liquid jetting head having a gap between head modules adjacent to each other.After performing pressurization purging for pressurizing an inside of a liquid jetting head (32) that is the liquid jetting head (32), which jets a liquid from a nozzle (202) disposed on a nozzle surface (33), is formed by a plurality of head modules (200), and has a gap (G) between the head modules adjacent to each other, to discharge the liquid from the nozzle (202), a long wiping web (104) in a dry state abuts against the nozzle surface (33) of the liquid jetting head (32) at a pressing force of 0 kPa or more and 15 kPa or less, and the wiping web (104) is transported with respect to the liquid jetting head (32) in a web transporting direction to wipe the nozzle surface (33).
