Title
(EN) EJECTION CONTROL USING IMAGER
(FR) COMMANDE D'ÉJECTION À L'AIDE D'UN IMAGEUR
Abstract
(EN)
A printing system includes a substrate support, a printhead assembly positioned facing the substrate support, and an imager. The printhead assembly includes a plurality of dispensing nozzles extending in an ejection direction towards the substrate support and a plurality of marks. The imager is movable relative to the printhead assembly and oriented in a direction opposite to the ejection direction for capturing at least one image including the plurality of marks indicating positions of the plurality of dispensing nozzles in the printhead assembly.

La présente invention concerne un système d'impression qui comprend un support de substrat, un ensemble tête d'impression positionné face au support de substrat, et un imageur. L'ensemble tête d'impression comprend une pluralité de buses de distribution s'étendant dans une direction d'éjection vers le support de substrat et une pluralité de marques. L'imageur est mobile par rapport à l'ensemble tête d'impression et orienté dans une direction opposée à la direction d'éjection pour capturer au moins une image comprenant la pluralité de marques indiquant des positions de la pluralité de buses de distribution dans l'ensemble tête d'impression.
