Abstract:
1. A duplex printing system for printing on sheets of media in a first printing mode and on a web of media in a second printing mode, comprising: a first printing station including a first drum and one or more first marking subsystems positioned to deposit a pattern of marking material on a first side of the media while a second side of the media is in contact with the first drum; a selectively activatable first drive mechanism for rotating the first drum; a second printing station including a second drum and one or more second marking subsystems positioned to deposit a pattern of marking material on the second side of the media while the first side of the media is in contact with the second drum; a selectively activatable second drive mechanism for rotating the second drum; a tensioning system for driving and adding tension to the web of media; and a control system for controlling the first and second drive mechanisms and the tensioning system; wherein when the duplex printing system is in the first printing mode sheets of media are transported along a sheet transport path such that: when the duplex printing system is in the second printing mode the first and second drive mechanisms are deactivated so that the first and second drums rotate freely, and the control system controls the tensioning system to transport the web of media along a web transport path such that:
