Abstract

CONTROLE AUTOMATIQUE DU FONCTIONNEMENT D'UNE IMPRIMANTE A JET D'ENCRE. LA CONTAMINATION DE L'ELECTRODE DE CHARGE PAR L'ENCRE TEND A CREER UN CHEMIN DE CONDUCTION A LA TENSION VCE1, ABAISSANT CELUI-CI ET RENDANT LA DIODE 80 CONDUCTRICE. UNE CHUTE DE TENSION APPARAISSANT EN 83 EST ALORS DETECTEE PAR L'AMPLIFICATEUR OPERATIONNEL 85 QUI FOURNIT DE CE FAIT UN SIGNAL EN VCE0. CE SIGNAL EST UTILISE POUR BLOQUER LE FONCTIONNEMENT DE L'IMPRIMANTE. IMPRIMANTES A GRANDE VITESSE.
