Device and method for regenerating a print head

摘要

A device (500) for regenerating a print head (103) of an inkjet printing device (100) is described. The device (500) is set up to apply a liquid (156) to the nozzle plate (180) of the printhead (103), and then the one or more nozzles (21, 22) of the printhead (103) with one or more non-eject pulses (301 ) operate to cause liquid (156) to be drawn from the nozzle plate (180) into the one or more nozzles (21, 22) and to mix with the ink in the one or more nozzles (21, 22), so that the viscosity of the ink in the one or more nozzles (21, 22) is reduced.
