  • Patent number: 6304737
    Abstract: A system in a xerographic apparatus which allows for a relatively easy, simple and fast method for mounting and positioning a AMAT photoreceptor belt onto the drive system frame and supporting structure for the belt. A flexible mounting boot is first placed over the photoreceptor frame and support structure and then the photoreceptor belt is positioned over the mounting boot such that the edges of the belt are prevented from catching onto any of the xerographic apparatus hardware thereby preventing damage to the belt. Thereafter the mounting boot is removed from the frame and support structure in such a manner so as to properly position the photoconductor belt on the frame and support structure. A certain amount of tensioning can then be applied to the photoconductive belt to allow it to move properly on its frame and support structure.

  • Patent number: 5543177
    Abstract: Disclosed are marking materials containing retroreflective fillers and processes for the use thereof. In one embodiment, images containing retroreflective fillers are generated on paper by any suitable means, such as electrostatic imaging and development with either dry or liquid developers, ink jet printing, strip-out development processes, or the like, and the images thus generated are used to control a document reproduction system. In another embodiment, images containing retroreflective fillers are generated on a movable part in an imaging apparatus, such as an imaging member, an intermediate transfer member, or the like, by any suitable means, and the images thus generated are used to impart information regarding the relative position of the movable part with respect to the copier or printer containing the movable part.
