  • Solenoid drive method that conserves power
    Publication number: 20100259861
    Abstract: A drive method for an impact-printhead solenoid is provided that improves power efficiency with an extremely simple circuit configuration and no sensors. Consisting only of a power-FET (Field-Effect Transistor) and PWM (pulse-width-modulation) signals from a printer-controller, this system, using a novel PWM frequency-optimization technique, reduces printhead power usage by as much as 13%.
