A power supply (340) may provide constant 40 volts and a power supply circuit (330) delivers driving voltage to an actuator unit (130) having N current sources (320) coupling a drive signal output to the electrodes of the corresponding channel wall. A current control signal is coupled to a data conversion unit (440) receiving print data and converting it into control signals for the sources, causing controlled movement of the actuator walls - Independent claims are included for an actuator control circuit, for a releasably attached print-head arrangement and for a power supply unit. |
