Abstract

Figures 1 and 2 show a schematic view of the process station in a copy cycle. A photoreceptor drum acquires a charge upon its surface at station 10 with imaging taking place at station 12. Lamp 14, shown in detail in Figure 2, comprises a pair of tungsten lamps 16, 17 at opposing ends of a diffusely reflective cavity 18. Light from the cavity emerges through aperture 20. A specularly reflective disk 22 is arranged within the cavity and adjustably mounted so as to slide along the axis of the cavity maintaining optical isolation between the two compartments thus formed.
