Abstract

L'invention concerne un appareil d'impression comprenant un réceptacle de tête d'impression pour recevoir une tête d'impression comprenant des structures fluidiques remplies d'un liquide d'expédition et un dispositif de commande. Le dispositif de commande effectue un processus de purge pour expulser le liquide d'expédition de la tête d'impression. Le dispositif de commande surveille une température de la tête d'impression pendant le processus de purge et détecte s'il existe une anomalie du processus de purge à l'aide de la température surveillée. S'il y a une anomalie du processus de purge, le dispositif de commande change les conditions de déclenchement du processus de purge et vérifie si l'anomalie est éliminée par modification des conditions de déclenchement. Le processus de purge se poursuit si l'anomalie est éliminée par modification des conditions de déclenchement.
