Abstract: The invention provides a printing system with a transport mechanism for transporting sheets. The transport mechanism comprises: a conveyor body for supporting and conveying a plurality of sheets a transport path; suction means, and especially fan means, for generating an under-pressure at or adjacent to the conveyor body to hold the sheets fixed in position on the conveyor body as it conveys the plurality of sheets along the transport path; and a controller for controlling or regulating operation of the suction means to adjust the under-pressure generated. The controller is configured to control operation of the suction means based on delivery of the plurality of sheets to the conveyor body and/or a change in the delivery of the sheets to the conveyor body. Further, the invention provides a corresponding method of transporting sheets of a print medium in a printing system.

Abstract: A sheet transport assembly is provided for transporting a sheet along a process unit configured for applying a process to the sheet. The sheet transport assembly comprises a conveying unit comprising a transport belt, which transport belt comprises air permeable openings, the sheet being placed with a contact side on a support surface of the transport belt; a separating unit for separating the sheet from the transport belt, the separating unit comprising a blowing unit connected to an air supply source and arranged adjacent the transport belt to direct a detach air flow through said air permeable openings of the transport belt in a detach area to lift the sheet from the transport belt; and a control unit configured for controlling the units of the sheet transport assembly. The separating unit further comprises a sheet attraction unit arranged for attracting the sheet to the support surface of the transport belt in two attraction areas. Said two attraction areas are cooperatively arranged adjacent to both sides of the detach area in a lateral direction, which is substantially perpendicular to the transport direction. The separating unit further comprises a sheet guidance element arranged facing the support surface of transport belt for separating a leading edge of the sheet from the transport belt, the sheet guidance element comprising a tip arranged proximate to the detach area.
