Title (EN) DROP-ON-DEMAND PRINT HEAD CLEANING MECHANISM AND METHOD
(FR) MÉCANISME ET PROCÉDÉ DE NETTOYAGE DE TÊTE D'IMPRESSION GOUTTE À LA DEMANDE
Abstract:
(EN) A card processing system includes a drop-on-demand card printing system that has at least one drop-on-demand print head with a nozzle plate. An automated cleaning mechanism is provided in the drop-on-demand card printing system that is configured to clean the nozzle plate without the cleaning mechanism physically contacting the nozzle plate. Since the nozzle plate is not physically contacted by the cleaning mechanism, damage to the nozzle plate during cleaning is avoided thereby avoiding degrading the resulting print quality of the print head.
(FR) L'invention concerne un système de traitement de carte comprenant un système d'impression de carte goutte à la demande qui comporte au moins une tête d'impression carte à la demande avec une plaque de buse. Un mécanisme de nettoyage automatisé est disposé dans le système d'impression de carte goutte à la demande qui est configuré pour nettoyer la plaque de buse sans que le mécanisme de nettoyage entre physiquement en contact avec la plaque de buse. Étant donné que la plaque de buse n'est pas physiquement en contact avec le mécanisme de nettoyage, un endommagement de la plaque de buse pendant le nettoyage est évité, ce qui permet d'éviter de dégrader la qualité d'impression obtenue de la tête d'impression.
