Abstract
A drum support structure of a production printing system is disclosed. The drum support structure secures a photoconductive drum within a printing system during operation. The drum support structure includes a plurality of ring members spaced in parallel along a longitudinal axis. The ring members have an outside diameter that corresponds with an inside diameter of the drum so that the ring members fit within the drum. The drum support structure also includes a plurality of connecting members that affix the ring members to one another. The drum support structure also includes an inner end cap that connects to an inner-most ring member through one or more connecting members and is adapted to contact one end of the drum. The drum support structure also includes an outer end cap that is adapted to fasten to an outer-most ring member and is further adapted to contact another end of the drum.
