Abstract
An illumination lamp assembly is provided for scan/illuminating a document during a document scan mode. The assembly includes an elongated lamp partially enclosed by a pair of elliptical reflectors. The lamp ends are centered at the focal point of the two reflectors and the lamp is releaseably secured between fixed end blocks and a retaining bias means arrangement which centers lamp at the reflector focal point and permits adjustment-free removal and replacement. Vibrational strobing of the lamp is decreased by providing at least one elastomeric O-ring around the lamp circumference to increase the lamp stiffness and raise the natural frequency of the lamp into a range where the resonant effects of the strobing are reduced.
