Abstract

Between the lamp 1 and photoconductor drum 2, two shields 3 and 4 are provided, shield 4 being close to the drum 2 surface. The aperture 5 of shield 3 is bow-shaped to compensate for the nonlinear power distribution of lamp 1, which may be an erase lamp. The aperture 6 in shield 4 is rectangular and defines footprint 7 of light on the surface of drum 2.
