Abstract
The adjustment of the strobe and data voltages to the array gates that drive each of the modulators in an ionographic printing device, in particular the lowering of the data voltage level below the strobe voltage level for each of the array gates. The lower limit on the data voltage level is the voltage level where the generated ions are not shut off completely at the modulating electrode.
