<p>PURPOSE:To make the clogging of a nozzle hard to generate, in an on-demand type ink jet printer, by using conductive ink and utilizing electromagnetic induction. CONSTITUTION:In an on-demand type ink jet printer using conductive ink, a loop is formed from at least two ink circulating passages 17, a common ink chamber 7 and the conductive ink 22 flowing through a pressure chamber. By passing AC magnetic fluxes due to electromagnetic coils 20a, 20b, 20c through the loop, electromagnetic induction is generated to circulate the conductive ink 22 and the ink of the pressure chamber and a nozzle is renewed to make the clogging of the nozzle hard to generate.</p> |
