Title
(EN) PRINT HEAD MAINTENANCE ASSEMBLY
(FR) ENSEMBLE DE MAINTENANCE DE TÊTE D'IMPRESSION
Abstract
(EN)
Disclosed herein is a print head maintenance assembly, a printing device and a method of cleaning a print head. The print head maintenance assembly comprises a maintenance cartridge comprising a wiping subsystem with a wiper for wiping a print head; a scraper assembly with a scraper for cleaning the wiper; and a positioner to adjust a relative position between the scraper and the wiper in a first direction depending on a relative position between the maintenance cartridge and the scraper assembly in a second direction.
(FR)
L'invention concerne un ensemble de maintenance de tête d'impression, un dispositif d'impression et un procédé de nettoyage d'une tête d'impression. L'ensemble de maintenance de tête d'impression comprend une cartouche de maintenance incluant un sous-système d'essuyage pourvu d'un élément d'essuyage destiné à essuyer une tête d'impression ; un ensemble racleur pourvu d'un racloir servant à nettoyer l'élément d'essuyage ; et un positionneur destiné à ajuster une position relative entre le racleur et l'élément d'essuyage dans une première direction en fonction d'une position relative entre la cartouche de maintenance et l'ensemble racleur dans une deuxième direction.
