Abstract (en)
Erroneous voltage readings of Electrostatic Voltmeters (ESVs), which have become contaminated by charged particles (i.e. toner) from developer housings (58,60) used for developing latent images on a photoreceptor surface (10), are negated by adjusting the readings of the ESVs (ESV1,ESV2) to compensate for the contamination of the ESVs. Additionally, the developer housing biases (70,71) are adjusted by an amount equal to the difference between the voltages measured by the ESVs thereby insuring proper development and cleaning fields during development. <IMAGE>
