Title
(EN) LOGIC CIRCUITRY PACKAGE
(FR) BOÎTIER DE CIRCUIT LOGIQUE
Abstract
(EN)
A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit and at least one logic circuit to transmit, via the interface, a limit parameter and a count threshold parameter. The logic circuit is to receive, via the interface, initial requests to read sensor IDs with the component connected to the apparatus and the apparatus not pneumatically actuating the component. The logic circuit is to transmit, via the interface, a resting state digital value in response to each initial request. The logic circuit is to receive, via the interface, further requests to read the sensor IDs with the component connected to the apparatus and the apparatus pneumatically actuating the component. The logic circuit is to transmit, via the interface, a further digital value in response to each further request.

L'invention porte sur un boîtier de circuit logique pour composant d'appareil d'impression remplaçable, qui comprend une interface pour communiquer avec un circuit logique d'appareil d'impression et au moins un circuit logique pour transmettre, par l'intermédiaire de l'interface, un paramètre de limite et un paramètre de seuil de nombre. Le circuit logique est destiné à recevoir, par l'intermédiaire de l'interface, des requêtes initiales pour lire des ID de capteur avec le composant relié à l'appareil et l'appareil n'actionnant pas pneumatiquement le composant. Le circuit logique est destiné à transmettre, par l'intermédiaire de l'interface, une valeur numérique d'état de repos en réponse à chaque requête initiale. Le circuit logique est destiné à recevoir, par l'intermédiaire de l'interface, des requêtes supplémentaires pour lire les ID de capteur avec le composant relié à l'appareil et l'appareil actionnant pneumatiquement le composant. Le circuit logique est destiné à transmettre, par l'intermédiaire de l'interface, une valeur numérique supplémentaire en réponse à chaque requête supplémentaire.
