    Abstract: The optical illumination and scanning system for document reproduction consists of two rotatable mirrors mounted in fixed side-by-side relationship. A light source illuminates the first mirror which reflects the light to a section of an original document. This light is reflected by the document to the second mirror which reflects this return beam through a lens system to a photoconductor surface. The mirror assembly oscillates across the entire original without changing the fixed relationship between the light beam reflected to the original and the return beam focused on the photoconductive surface.

    Abstract: A toner concentration control system for an electrostatic copier wherein light is alternately reflected from multicomponent developer material containing toner and from a calibrated reflector to a photosensor. An imbalance of toner in the developer material results in a difference in reflected light intensity from the developer and reflector which is converted into an electrical signal having an AC component. A phase sensing circuit detects the position of the peak of the AC signal component with reference to the position of the calibrated reflector and provides a control signal to a toner replenishing device. Developer flow past the photosensor is intermittently halted during concentration sensing to reduce noise effects. A plurality of selectable calibrated reflectors provide different concentration settings. Additional concentration settings are obtained by varying the light spectrum emitted by the light source.
