Abstract
A print engine is provided for electrophotographically transferring an image from an image source to an image-support member. The print engine includes a photoconductive member having a photoconductive surface for storing a latent, electrostatic image. A photoconductive drum charger and an image transfer device generate the latent, electrostatic image on the photoconductive surface. A developer station supplies developer to the latent, electrostatic image as it is being carried by the photoconductive surface to provide a developed image. A carrier member includes an electrically charged support surface for supporting an image-support member which is passed through an image transfer nip. The image transfer nip extends between the photoconductive member and the carrier member. The image-support member and the developed image are simultaneously passed through the image transfer nip so that the developed image is transferred to the image-support member. A mounting assembly is provided for movably supporting the photoconductive member and the carrier member in a relative frictional engagement therebetween, wherein the carrier member is pressed into the photoconductive member so that the…
