Method of operating and an apparatus using an ink jet head having serially connected energy generating means |
摘要 |
An ink jet recording head has an energy generating device line constituted by electrically connecting N (N>1) energy generating devices in series. The energy generating devices are disposed to correspond to a plurality of discharge ports for discharging ink and generate discharging energy. The energy generating device line is operated by using substantially N+1 electrodes. The method of operating an ink jet recording head comprises the steps of: successively selecting the energy generating devices of the energy generating device line; applying voltages of different levels to the two terminals of the selected energy generating device having received an image signal instructing the selected energy generating device to discharge the ink; and applying voltages of the same level to the two ends of the energy generating device which corresponds to the discharge ports which are not to discharge the ink.
