Abstract

La présente invention concerne un procédé et un dispositif de vérification de dispositif de commande de machine. de reproduction. Ce procédé de vérification comprend les étapes suivantes : envoyer un signal de test à l'élément commandé; lire en retour le signal de sortie en provenance de l'élément commandé; comparer le signal de sortie de l'élément commandé au signal de test envoye à cet élément; et déclarer un défaut de la machine quand la sortie de signal en provenance de l'élément commande diffère du signal de test envoyé à l'élément commandé. Application aux machines xérographiques à grande vitesse.
