Title
(EN) LOGIC CIRCUITRY
(FR) CIRCUITERIE LOGIQUE
Abstract
(EN)
A sensor circuit for a replaceable print apparatus component comprises an interface to transmit signals with respect to a print apparatus logic circuit, and further comprises, connected to the interface, at least two sensor cell arrays, each array including nominally the same cells, the cells of one array being nominally different than the cells of the other array, and at least one single cell sensor that is nominally different than the other cells.

La présente invention concerne un circuit de capteur pour un composant d'appareil d'impression remplaçable qui comprend une interface pour transmettre des signaux par rapport à un circuit logique d'appareil d'impression, et comprend en outre, connectés à l'interface, au moins deux réseaux de cellules de capteur, chaque réseau comprenant nominalement les mêmes cellules, les cellules d'un réseau étant nominalement différentes des cellules de l'autre réseau, et au moins un capteur de cellule unique qui est nominalement différent des autres cellules.
