Title
(EN) DETERMINING A PRINT MEDIA MALFUNCTION CONDITION
(FR) DÉTERMINATION D'UNE CONDITION DE DYSFONCTIONNEMENT DE SUPPORTS D'IMPRESSION
Abstract
(EN) Examples of the method may comprise providing a print media (2) under a printhead (1) of the printing system, obtaining an actual height profile signal, related to a height between the printhead (1) and the print media (2), based on measurements taken at a plurality of positions across the width of the media (2) during at least one pass, comparing said actual height profile signal to an earlier height profile signal, obtained based on measurements taken at said plurality of positions across the width of the media (2) during at least one earlier pass on the same print media (2), and determining a media malfunction condition based on said comparison.
(FR) Des exemples du procédé peuvent consister à fournir un support (2) d'impression sous une tête (1) d'impression du système d'impression, obtenir un signal de profil de hauteur réelle, en rapport avec une hauteur entre la tête (1) d'impression et le support (2) d'impression, en se basant sur des mesures prises au niveau d'une pluralité de positions sur la largeur du support (2) pendant au moins une passe, comparer ledit signal de profil de hauteur réelle à un signal de profil de hauteur antérieur, obtenu sur la base de mesures effectuées au niveau de ladite pluralité de positions sur la largeur du support (2) au cours d'au moins un passage antérieur sur le même support (2) d'impression, et déterminer une condition de dysfonctionnement du support sur la base de ladite comparaison.
