ABSTRACT:
Provided is a system for reducing unwanted background writing effects caused by an elevated OFF voltage state on a print head in an electrographic printing system. This system allows for the OFF voltage to be elevated through the use of modulated OFF states. The OFF voltage is pulsed, or modulated, between a required OFF voltage and a voltage less than the required OFF voltage, during an OFF state, thus reducing erroneous background writing events while maintaining image quality. The system provides a modulated voltage source to be used during the OFF state and an additional constant voltage source to be used during a writing state.
