ABSTRACT:
An electrographic apparatus has a photoconductor on which a latent image is formed, and a development station provides particles of toner to the photoconductor for developing a latent image. After the developed image has been trnsferred to a copy sheet, residual toner particles remaining on the photoconductor are removed at a cleaning station. The removed toner particles are either returned to the development station of the electrographic apparatus for reuse or delivered to a container for disposal. For example, if a development station providing black toner particles to a photoconductor is replaced with a development station containing toner particles of a different color, the residual black toner particles removed at the cleaning station are delivered to the container in order to avoid contamination of colored tone particles in the development station with those black particles remaining on the photoconductor from the operation of the black development station operation.
