A document carrier device for supporting and transporting a document in a document processing system, wherein the document carrier device comprises: a workpiece carrier comprising a support surface (105a, b) for receiving a document; a heating device comprising a heat conducting element for transferring heat generated by the heating device; and an actuator (135a, 135b) for causing relative movement between the heat conducting element and the workpiece carrier in order to change between a first mode of operation and a second mode of operation of the document carrier device, wherein, in the first mode of operation, the heat conducting element extends, without thereby being in mechanical contact with the workpiece carrier, through one or more recesses in the workpiece carrier in the region of the support surface (105a, b) in order to be able to transfer heat generated by the heating device, at least in part, to a document received on the support surface (105a, b) of the workpiece carrier; and wherein, in the second mode of operation, the heat conducting element has a distance from the support surface (105a, b) which is increased when compared with its position in the first mode of operation; wherein the document carrier device further comprises a sensor device which is configured to detect, in a sensor based manner, a temperature of the workpiece carrier or of a document supported thereon, or another technical variable that is in a dependent relationship with said temperature; wherein the document carrier device is configured to control the heating device as a function of the temperature or other technical variable detected by means of the sensor device. a workpiece carrier comprising a support surface (105a, b) for receiving a document; a heating device comprising a heat conducting element for transferring heat generated by the heating device; and an actuator (135a, 135b) for causing relative movement between the heat conducting element and the workpiece carrier in order to change between a first mode of operation and a second mode of operation of the document carrier device, wherein, in the first mode of operation, the heat conducting element extends, without thereby being in mechanical contact with the workpiece carrier, through one or more recesses in the workpiece carrier in the region of the support surface (105a, b) in order to be able to transfer heat generated by the heating device, at least in part, to a document received on the support surface (105a, b) of the workpiece carrier; and wherein, in the second mode of operation, the heat conducting element has a distance from the support surface (105a, b) which is increased when compared with its position in the first mode of operation; wherein the document carrier device further comprises a sensor device which is configured to detect, in a sensor based manner, a temperature of the workpiece carrier or of a document supported thereon, or another technical variable that is in a dependent relationship with said temperature; wherein the document carrier device is configured to control the heating device as a function of the temperature or other technical variable detected by means of the sensor device.
