Method and system for high velocity document processing system using lower velocity print technology

A transporting system and method for use in a high velocity document processing system using lower velocity print technology. An upstream transport (21) conveys spaced apart documents (1, 2) at a first transport velocity. A deceleration transport (41) decelerates documents from the high speed to a lower print velocity before passing the documents a print transport (11, 12, 13, 14). A sensor (42) located at the deceleration transport, detects the presence of documents at the deceleration transport, and triggers the deceleration profile to be performed on the document. The deceleration transport (41) is controlled such that a leading portion of a document (2) that is being decelerated overtakes a trailing portion of a downstream document (1) that already travelling at the lower print velocity in the control of the print transport. The lead portion of the upstream document (2) is urged to overlap on top of the trailing portion of the downstream document (1) when the upstream document overtakes the downstream document. A print head (15) prints on the transported documents (1, 2) at the print transport velocity.
