Abstract: A paper transport is formed by a plurality of substantially identical conveyor modules which are arranged end-to-end and separated by gaps selected as a function of active devices which are to be installed along the paper path defined by the transport. The conveyor modules each include plural conveyor belts and documents are held against the belts for transport there through the creation of a small pressure differential thereacross, the pressure differential resulting from establishing a large volume air flow through the conveyor modules, the same air flow being employed for cooling the electronic components of the active devices associated with the transport.
