<p>An ink on demand type ink jet head energization system is provided to drive ink out of a nozzle in the head. The head (40, 42) contains at least one nozzle (59) for discharging ink. A low voltage power supply (28) is located away from the head (40, 42) to supply low voltage power to the head (40, 42). Connector leads (44, 46) are provided to connect the head (40, 42) to the power supply (28). Carried on the head (40, 42) is a voltage conversion circuit (66) for converting the low voltage power supplied to the head (40, 42) into a high voltage driving signal to discharge ink from the head (40, 42).</p> |
