ABSTRACT:
A transporting system and method for use in a high velocity document processing system using lower velocity print technology. The invention including an upstream transport conveying spaced apart documents at a first transport velocity. A deceleration transport decelerates documents from the high speed to a lower print velocity before passing the documents a print transport. A sensor 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 is controlled such that a leading portion of a document that is being decelerated overtakes a trailing portion of a downstream document that already traveling at the lower print velocity in the control of the print transport. An overlapping arrangement urges the lead portion of the upstream document to overlap on top of the trailing portion of the downstream document when the upstream document overtakes the downstream document. A print head prints on the transported documents at the print transport velocity.
