Abstract

La presente invención se refiere a lecturas de voltaje erróneas de Voltímetros Electrostáticos (ESVs), que se han contaminado con partículas cargadas (es decir pigmento) a partir de alojamientos de revelador empleados para revelar imágenes latentes en una superficie fotorreceptora, que son negadas al ajustar las lecturas de los ESVs para compensar la contaminación de los ESVs. Adicionalmente, se ajustan las derivaciones de alojamiento revelador por una cantidad igual a la diferencia entre los voltajes medidos por los ESVs, asegurando de esta manera un revelado adecuado y campos de limpieza durante el revelado.
