Abstract: An imaging module mounting structure is used for mounting an imaging module to an imaging device that has a support member and a rotatable photoreceptor. The imaging module includes an imaging bar and a corona generating device. The imaging module mounting structure includes a pair of pivot block devices which are pivotably connected to the support member in a spaced apart relationship. The imaging bar and the corona generating device are secured to each one of the pair of pivot block devices. Each pivot block device includes a cam follower element. The pair of pivot block devices are operative to flex independently of one another while the photoreceptor rotates so that the respective cam follower elements remain in contact with the rotating photoreceptor to compensate for photoreceptor run out. A method for practicing the present invention is also described.
