    • Printing machines and systems which incorporate recharging stations comprised of two corona generating devices which act together to recharge a previously developed photoreceptor to a predetermined potential. The first corona generating device recharges the photoreceptor's surface to a greater absolute potential than a predetermined potential which the surface is to have after being recharged. The second corona generating device reduces the photoreceptor's surface to the potential that it is to have. The second corona generating device is comprised of a plurality of spaced apart coronodes which each can impress charges on the photoreceptor's surface. The second corona generating device receives electrical inputs and applies DC potentials to the coronodes such that adjacent coronodes have opposite polarities.
