Abstract: Ink-jet printer and method for supplying ink-jet printer with printing fluid. Device includes first reservoir configured to contain first volume of printing fluid at first level relative to reference plane, supply system structured to force printing fluid towards first reservoir, and second reservoir configured to contain second volume of printing fluid at second level relative to reference plane. Second level is lower than first level by level difference value. A conduit is configured to receive printing fluid from first reservoir and convey printing fluid towards second reservoir, and ejector units are arranged to receive printing fluid from conduit. An ejection plane in which ejector units lie is located at a height relative to reference plane higher than average of first and second levels to generate a back pressure in ejector units. Flowrate of printing fluid inside conduit is greater than a maximum flowrate of printing fluid ejectable from ejector units.

Abstract: An ink-jet printing device is described, said device comprising a first reservoir designed to contain a first volume of printing fluid at a first height with respect to a reference plane, a supply system for forcing the printing fluid towards the first reservoir and a second reservoir designed to contain a second volume of printing fluid at a second height with respect to the reference plane. The second height is less than the first height by a value. The device also comprises a conduit designed to receive the printing fluid from the first reservoir and convey it towards the second reservoir and an ejection plane in which ejector units lie. The ejection plane is arranged in a position higher than the average of the first height and the second height, so as to generate a back pressure in the ejector units. The flowrate of the printing fluid is between about 5 and about 10 times the maximum flowrate which can be ejected from said ejector units. The printing fluid may be a ceramic ink.
