The invention relates to a sheet stacking device for a sheet handling system and further to a method and a computer program product for controlling a sheet stacking device of a sheet handling system. The sheet stacking device (1) comprises at least one sheet entrance pathway (10) for receiving incoming sheets and a sheet output unit (20) with at least one output tray (21) for stacking the received sheets to form a at least one stack (24a, 24b) on the at least one output tray (21). The sheet stacking device (10) further comprises a control unit (30) for determining the weight of the stack (24a, 24b) on the at least one output tray (21) and for providing a control signal (31) if the determined weight exceeds a predetermined value, and a stack separating mechanism (23) for distinguishing two or more stacks (24a, 24b) on the same output tray, said stack separating mechanism being controlled by the control unit (30) to limit the weight of the distinguished stacks.

The invention relates to a method for ejecting a stack of sheets from an output holder attached to a printing device, the output holder configured to hold a stack of sheets printed upon by the printing device according to a plurality of print jobs submitted to the printing device, the printing device comprising a control unit for controlling the receiving of the plurality of print jobs in a print job queue and the printing of the plurality of print jobs according to the print job queue, the method comprising the steps of receiving a trigger comprising information for an ejection of the stack for another reason than a full output holder, the stack ejection to be performed before the start of the printing of a print job residing in the print job queue or after the print job residing in the print job queue has been printed, and entering a task for the ejection of the stack at a position in the print job queue, the position determining an intended moment in time of the ejection of the stack corresponding to the information comprised in the trigger. The invention also relates to a printing system configured to execute the method according to the present invention.

The invention relates to a print system and a method for stopping the print system from printing. The print system comprises a control unit for controlling the printing of sheets, a print engine for printing recording material on the sheets, an input tray for holding sheets to be printed upon, and a finishing unit. The method comprises the steps of scheduling a plurality of sheets for printing by the print engine and for finishing by the finishing unit, the scheduling step comprising a first step of sending a sheet request for a sheet of the plurality from the control unit to the finishing unit and a second step of, upon receiving the sheet request, replying by the finishing unit an earliest expected arrival time of the sheet at the finishing unit, which earliest expected arrival time is respected by the print engine as a minimum delay time between the sheet and a previous sheet preceding the sheet, wherein in case of an exception which requires operator intervention the method comprises the steps of submitting an earliest expected arrival time by the finishing unit to the control unit which is so huge that a gap in time between a particular sheet which has not left the input tray and a previous sheet which is preceding the particular sheet becomes larger than a travel time of the previous sheet from the input tray to the finishing unit, submitting an artificial notification by the finishing unit to the control unit, after the previous sheet has been deposited in the finishing unit, the artificial notification reporting a severe error at the print system that normally leads to a print engine stop, and stopping the print engine by the control unit before the particular sheet leaves the input tray.

The invention relates to a method of using an interface device to interface to a processing unit (28), the interface device and the processing unit being comprised in a station (12) of a plurality of stations (12,14,16) in a sheet processing line, the method comprising - using the interface device (34) to receive a control signal from an upstream station (10). The method comprises - determining a comparison result by comparing a selection part of the control signal with a reference, the selection part being comprised in an addressing part of the control signal; - in case of a negative comparison result, determining a further control signal from the control signal, at least a further addressing part of the further control signal being derived from and differing from the addressing part of the control signal and using the interface device to output the further control signal to a further interface device corresponding to a further processing unit of a downstream station; and - in case of a positive comparison result, sending an instruction signal from the interface device to the processing unit.
