Active airflow control device for vacuum paper transport
Abstract:
A marker transport system and a method of operating the marker transport system can include one or more print heads and a marker transport platen upon which a sheet of media moves. The transport platen can include airflow sections comprising process-direction slots. The plates can move in a cross-process direction, and can control airflow in an area under the print heads. The one or more plates in a first position can allow for airflow when the sheet of media is located at the first position and in a second position can block the airflow at the second position. A vacuum can be provided under the sheet of media as the sheet of media traverses a print path across the marker transport platen. A no-vacuum inter-document zone can be provided, which moves along with the sheet of media under the one or more print heads.
