Abstract: A method of managing a queue of print jobs in a printer is disclosed, wherein the jobs are created by specifying print data and print parameters for each job, and the jobs are put into the print queue, and wherein, before print processing of a job in the queue begins, a start condition for the job is checked and printing is started only when the start condition is fulfilled. The method includes steps of checking a status of mode indicator specifying whether the printer is in a “keep going” mode or a “keep sequence” mode; and, when a job in the queue is reached for which the start condition is not fulfilled, postponing print processing of this job and proceeding with a next job, if any, for which the start condition is fulfilled, if the printer is in the “keep going” mode, or stopping print processing, if the printer is in the “keep sequence” mode.

Abstract: An image reproduction device is provided with an automatic feed unit for documents; a double-sheet detector for detecting more than one sheet as the document for copying; an operator control unit provided with an operator control panel; and a control unit for controlling the automatic feed unit, processing the signal from the double-sheet detector and controlling the operator control unit. The device which is also provided with an operator control unit adapted to offer a choice between switching the double-sheet detector on or off is thus suitable for the image reproduction of documents in cases in which, dependent on the presence of documents consisting of more than one sheet, the operator is offered the free choice of adapting the operation of the image reproduction device thereto.

Abstract: An image reproduction device is provided with an automatic feed unit for documents; a double-sheet detector for detecting more than one single sheet as the document for copying; an operator control unit provided with an operator control panel; and a control unit connected to the said units for controlling the automatic feed unit, processing the signal from the double-sheet detector and controlling the operator control unit. The device is also provided with an operator control unit adapted to offer a choice between switching the double-sheet detector on or off. This device is thus suitable for the image reproduction of documents in cases in which, dependent on the presence of documents consisting of more than one sheet, the operator is offered the free choice of adapting the operation of the image reproduction device thereto.
