Abstract
(EN)
The present invention addresses the problem of providing a recording head cleaning device, a recording head cleaning method, and a recording device that clean a nozzle surface while preventing entry of a cleaning liquid from a nozzle. The problem is solved by a recording head cleaning device provided with: a cleaning liquid retention unit having a cleaning liquid retention surface; a cleaning liquid providing unit that provides a cleaning liquid to the cleaning liquid retention surface; a cleaning unit that cleans, with the cleaning liquid retained at the cleaning liquid retention surface, a nozzle surface at which a nozzle for ejecting ink of a recording head is arranged, with the cleaning liquid retention surface opposed to the nozzle surface; and a back pressure control unit that makes the back pressure of the nozzle during the cleaning of the nozzle surface at -800 Pa to -200 Pa.

La présente invention aborde le problème lié à la fourniture d'un dispositif de nettoyage de tête d'impression, d'un procédé de nettoyage de tête d'impression et d'un dispositif d'impression qui nettoient une surface de buse tout en empêchant l'entrée d'un liquide de nettoyage à partir d'une buse. Le problème est résolu par un dispositif de nettoyage de tête d'impression comprenant : une unité de rétention de liquide de nettoyage ayant une surface de rétention de liquide de nettoyage ; une unité de fourniture de liquide de nettoyage qui fournit un liquide de nettoyage à la surface de rétention de liquide de nettoyage ; une unité de nettoyage qui nettoie, avec le liquide de nettoyage retenu au niveau de la surface de rétention de liquide de nettoyage, une surface de buse au niveau de laquelle une buse pour éjecter de l'encre d'une tête d'impression est agencée, la surface de rétention de liquide de nettoyage étant opposée à la surface de buse ; et une unité de commande de contre-pression qui amène la contre-pression de la buse pendant le nettoyage de la surface de buse entre -800 Pa et -200 Pa.
