Abstract
Disclosed is a method to optimize the operation of an ink-jet printer provided with a circuit to collect the ink not used for the printing, comprising a gutter connected to an imperviously sealed ink tank by a conduit placed in a state of depression by a constant flow pump checking the flow rate of ink in the conduit by the measurement of the pressure in the ink tank and controlling the operation of the pump either at its minimum suction rate compatible with efficient collection of the ink or at its maximum suction rate during anomalies of collection.
