Title
(EN) WIDE ARRAY FLUID EJECTION DEVICE
(FR) DISPOSITIF DE PROJECTION DE FLUIDE A LARGE RESEAU
Abstract
(EN)
A fluid ejection device includes a first set of N memory elements (104/204) each storing a fire enable value, each of the N memory elements configured to be updated. The fluid ejection device further includes N fluid ejecting elements (102/202), each fluid ejecting element corresponding to a different one of the N memory elements and configured to receive the fire enable value from the corresponding memory element, wherein the fluid ejecting element is enabled to eject a fluid when the fire enable value is an enabling value.
(FR)
L'invention concerne un dispositif de projection de fluide comprenant un premier ensemble d'éléments mémoires N (104/204) stockant chacun une valeur de validation d'amorce, chaque élément mémoire N devant être mis à jour. Le dispositif de projection de fluide comporte également des éléments de projection de fluide N (102/202), chacun d'eux correspondant à un élément mémoire N différent et étant conçu pour recevoir la valeur de validation d'amorce de l'élément mémoire correspondant, l'élément de projection de fluide pouvant projeter un fluide lorsque la valeur de validation d'amorce est une valeur de déclenchement.
