Title
(EN) LOGIC CIRCUITRY
(FR) CIRCUITERIE LOGIQUE
Abstract
(EN)
In an example, a method comprises, by logic circuitry associated with a replaceable print apparatus component installed in a print apparatus, receiving a sensor data request and determining whether the request is for data indicative of a print material level or for data indicative of a pressurisation event. In the event that the request is a request for data indicative of the print material level, the method may comprise responding with a first data response in a first value range; and in the event that the request is a request for data indicative of a pressurisation event, the method may comprise responding with a second data response in a second value range.
(FR)
La présente invention concerne, dans un exemple, un procédé qui consiste, au moyen d'une circuiterie logique associée à un composant d'appareil d'impression remplaçable installé dans un appareil d'impression, à recevoir une requête de données de capteur et à déterminer si la requête est ou non pour des données indiquant un niveau de matériau d'impression ou pour des données indiquant un événement de pressurisation. Dans le cas où la requête est une requête de données indiquant le niveau de matériau d'impression, le procédé peut consister à répondre avec une première réponse de données dans une première plage de valeurs ; et dans le cas où la requête est une requête de données indiquant un événement de pressurisation, le procédé peut consister à répondre avec une seconde réponse de données dans une seconde plage de valeurs.
