摘要： The invention relates to a method of cleaning doctor devices (10) of inking units in a printer, comprising emptying the ink from an ink chamber, through feed (11) and drainage (12) tubes, into an ink tank (13) and supplying solvent into said ink chamber, followed by emptying said solvent form the ink chamber, carrying out all of said actions by using a dynamic fluid pump (15), with a first and second diaphragms of different sizes, one of the faces thereof defining respective pumping (15a) and suction (15b) chambers, said suction chamber (15b) having a greater volumetric capacity. In said method the ink is circulated for emptying by means of said pumping (15a) and suction (15b) chambers, the former being used in reverse, and solvent is supplied by entering said pumping chamber (15a) and exiting through said suction chamber (15b).
