Abstract: PROBLEM TO BE SOLVED: To effect optimum cleaning based on the ambient temperature by a method wherein ambient temperature is detected and conditions upon effecting the cleaning are set based on the detecting result of the ambient temperature. SOLUTION: When a print head 3 is at a maintenance position, the surface of the print head 3 provided with a nozzle is brought into close contact with a suction cap 16 and a pulse voltage for flying ink is impressed on the print head 3 while sucking air by a piston pump 17 to discharge ink and effect self purge. By this method, bubbles, dust and the like which are adhered to the peripheral rim of the nozzle and affecting on printing are removed. In this case, the time for which the maximum amplitude of the pulse voltage impressed to drive the piezoelectric element of the print head 3 upon the self purge is kept is increased or decreased in accordance with the decrease or increase of the ambient temperature considering that the viscosity of the ink is increased and cleaning of the ink sludge becomes hard by the reduction of the ambient temperature.
