Claim:
A method for controlling the transport of sheets through a printing apparatus having at least one print module and a transport arrangement defining a direction of transport, arranged for transporting sheets past said at least one print module for printing thereon, said method comprising the steps of: (a) setting a print queue by assigning images to respective sheets, prior to feeding the respective sheets into the transport arrangement; (b) feeding sheets into the transport arrangement; (c) detecting whether a double sheet feeding has occurred; (d) deflecting superposed double sheets to a double sheet box, which is arranged upstream of the at least one print module; (e) guiding any non-superposed sheets following the superposed double sheet in the transport arrangement, for which an image has already been assigned and which are not in a duplex path, to a waste box, which is arranged downstream of the at least one print module; and (f) automatically resetting the print queue and continuing to print without stopping the printing apparatus.
