Abstract

In un modulo di stampa a getto di inchiostro comprendente una testina di stampa fissata sul proprio serbatoio, un circuito di misura permette di misurare in modo lineare e senza isteresi le variazioni della quantità di inchiostro contenuto nel serbatoio e di segnalare almeno uno degli estremi dell'intervallo di variazione per indicare il momento più opportuno per ricaricare d'inchiostro il serbatoio per mezzo di una cartuccia inseribile nel serbatoio.
