Title (EN) PRINTER DRYER MONITOR
(FR) MONITEUR DE SÉCHOIR D’IMPRIMANTE
Abstract:
(EN) A circuit includes a pulse generator to generate an output pulse in response to a signal representing rotation of a fan. A timing relationship between output pulses represents speed of the fan. A filter circuit converts the output pulse to a direct current (DC) voltage signal proportional to the speed of the fan. A monitor circuit monitors the DC voltage signal with respect to a predetermined threshold and generates a control signal that disables a printer dryer if the DC signal does not satisfy the predetermined threshold.
(FR) La présente invention concerne un circuit qui comprend un générateur d’impulsions pour générer une impulsion de sortie en réponse à un signal représentant la rotation d’un ventilateur. Une relation temporelle entre les impulsions de sortie représente la vitesse du ventilateur. Un circuit de filtre convertit l’impulsion de sortie en signal de tension en courant continu (CC) proportionnel à la vitesse du ventilateur. Un circuit de surveillance surveille le signal CC par rapport à un seuil prédéterminé et génère un signal de commande qui désactive un sécheur d’imprimante si le signal CC ne satisfait pas au seuil prédéterminé.
