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 sensor ID parameter and a limit parameter, the sensor ID parameter indicating a first sensor ID. The logic circuit is to receive, via the interface, a first request corresponding to the first sensor ID 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 first digital value in response to the first request. The logic circuit is to receive, via the interface, a second request corresponding to the first sensor ID with the component connected to the apparatus and the apparatus pneumatically actuating the component. The logic circuit is to transmit, via the interface, a second digital value in response to the second request. A difference between the first digital value and the second digital value is greater than the limit parameter.

La présente invention concerne un boîtier de circuit logique pour un composant d'appareil d'impression remplaçable, ledit boîtier comprenant 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 d'identifiant de capteur et un paramètre limite, le paramètre d'identifiant de capteur indiquant un premier identifiant de capteur. Le circuit logique est destiné à recevoir, par l'intermédiaire de l'interface, une première demande correspondant au premier identifiant de capteur, le composant étant connecté 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 première valeur numérique en réponse à la première demande. Le circuit logique est destiné à recevoir, par l'intermédiaire de l'interface, une seconde demande correspondant au premier identifiant de capteur, le composant étant connecté à l'appareil et l'appareil actionnant de manière pneumatique le composant. Le circuit logique est destiné à transmettre, par l'intermédiaire de l'interface, une seconde valeur numérique en réponse à la seconde demande. Une différence entre la première valeur numérique et la seconde valeur numérique est supérieure au paramètre limite.
