A control system (40) is disclosed for an ink jet printer. The control system employs acoustic transducers (12, 13, 15) to determine the velocity of sound in the ink and in a reference chamber (10) containing only fresh ink. By comparing the two measurements it can be determined when to add additional solvent to the system to maintain solids concentration substantially constant.
Système de commande (40) pour imprimante à jet d'encre dans lequel des transducteurs acoustiques (12, 13, 15) déterminent la vitesse du son dans l'encre et dans une chambre de référencs (10) qui ne contient que de l'encre neuve. La comparaison des deux mesures permet de déterminer le moment où du solvant supplémentaire doit être ajouté dans le système pour que la concentration en solides reste sensiblement constante.
