Abstract

The invention relates to a method of re - circulating fluids in an inkjet printing system and which uses a fluid flow along nozzles located in an inkjet printer head so that the positive pressure and the negative pressure equalize at the entrance to a printing head reservoir and the exit out of the reservoir with the aim of preventing clogging of the inkjet printer head nozzles. The invention relates further to a device that uses the described method.
