Coupling mechanism for material supply module

A material supply module for detachable connection to a reprographic device, said module comprising:

• a housing;
• a photoreceptor drum joined with said housing, said photoreceptor drum including a cylinder flange joined to one end thereof, and said flange having a concentric shaft extending axially outwardly therefrom;
• and
• a cylindrical coupling member extending axially outwardly from the concentric shaft and comprising a flexible membrane that encases non-rigid material therein, wherein, during use, said non-rigid material substantially solidifies, and said membrane has a substantially non-flexible structure, wherein said photoreceptor drum is configured to be detachably connected to a driving coupling attached to the reprographic device, the driving coupling defines a triangular socket through a center thereof, and the cylindrical coupling member is configured to fit within said triangular socket, and further wherein said socket includes a truncated, axially outwardly extending conical pin through the center thereof, and said membrane of the cylindrical coupling member defines an axial hole through the center thereof for receiving said conical pin.
