Title
(EN) ASSISTED EJECTION OF PRINT JOBS
(FR) ÉJECTION ASSISTÉE DE TRAVAUX D'IMPRESSION
Abstract
(EN)
A method of controlling the ejection speed of a print job that includes, with a density module of a printing device, determining a density classifier based on a region of a plane where print fluid is to be printed for a plurality of sheets of media of a print job; determining a percentage of each sheet of media exceeding a threshold density classifier relative to a total sheet count of the print job; and, based on the percentage, initiating an assisted ejection of the print job from the printing device.
(FR)
L'invention concerne un procédé de commande de la vitesse d'éjection d'un travail d'impression qui comprend, avec un module de densité d'un dispositif d'impression, la détermination d'un classificateur de densité sur la base d'une région d'un plan où un fluide d'impression doit être imprimé pour une pluralité de feuilles de support d'un travail d'impression ; la détermination d'un pourcentage de chaque feuille de support dépassant un classificateur de densité de seuil par rapport à un nombre total de feuilles du travail d'impression ; et, sur la base du pourcentage, l'initiation d'une éjection assistée du travail d'impression à partir du dispositif d'impression.
