Abstract
The size of patterns printed by an ink jet system printer including an ink liquid issuing nozzle, a charging electrode and deflection electrodes is temperature dependent. When the ink liquid temperature increases, viscosity of the ink liquid reduces and hence a flow rate of the ink liquid increases. This causes both mass and a flying rate of an ink droplet emitted from the nozzle to increase. Therefore, a deflection amount becomes smaller and hence the printed pattern size becomes smaller than that of ordinary desired. A temperature senser is provided on an ink conduit adjacent to the nozzle, for detecting the ink liquid temperature and generating detecting signals. A voltage level of video signals applied to the charging electrode or a voltage level applied to the deflection electrodes is varied in accordance with the detecting signals in order to stabilize the size of the printed pattern. When the ink liquid temperature increases, the voltage level of the video signals applied to the charging electrode or the voltage level applied to the deflection electrodes is compensatively increased.
