Abstract: A vacuum drum for securing and retaining different sizes of flexible sheet media has cylindrical surface holes connection different sets of longitudinal bores connected to right and left end radial bore distribution rings. The rings are adapted to be selectively separately connected to external sources of vacuum to provide first and second evacuation zones on the drum surface. A preferred embodiment has left and right shaft section ports connected so that application of a vacuum source to the left port evacuates a first drum zone for holding a smaller sized media, and connection of both left and right ports to a vacuum source evacuates both first and second drum zones for holding a larger media.
