摘要： An impact printer has a flux regulator for each of the coils in its printhead. Each regulator provides a reference voltage indicative of the desired flux in the associated coil. A circuit is provided for measuring the flux in the coil and for providing a voltage representative thereof. The measured flux representation is compared with the reference flux representation and any difference is applied to a power circuit which then provides more or less power to the associated coil.
