Title (EN) EVALUATING PRINT NOZZLE CONDITION
(FR) ÉVALUATION D'UN ÉTAT DE BUSE D'IMPRESSION
Abstract: front page image
(EN) Systems and methods for evaluating the condition of a print nozzle are described. In one example, impedances across the print nozzle are measured. Subsequently, first test result and second test result are determined and registered at a first predetermined time instant and at a second predetermined time instant, respectively. The first test result and the second test result are obtained based on the measured impedances. Based on the first test result and the second test result, the condition of the print nozzle, is determined.
(FR) L'invention concerne des systèmes et des procédés permettant d'évaluer l'état d'une buse d'impression. Selon un exemple, les impédances à travers la buse d'impression sont mesurées. Par la suite, un premier résultat de test et un second résultat de test sont déterminés et enregistrés à un premier instant prédéterminé et à un second instant prédéterminé, respectivement. Le premier résultat de test et le second résultat de test sont obtenus sur la base des impédances mesurées. Sur la base du premier résultat de test et du second résultat de test, l'état de la buse d'impression est déterminé.
