A method for making available measuring data of a value-document processing apparatus for processing value documents includes feeding individual value documents in real time, measuring data for the value documents are captured by means of a sensor device and stored in an intermediate memory, such that feeding of individual value documents and/or the capturing of measuring data the current utilization of the intermediate memory is compared to a predetermined limit utilization, dependent on the comparison. The feeding of value documents is interrupted and measuring data from the intermediate memory are permanently stored in a permanent memory, and during the permanent storing and/or after the permanent storing of the measuring data in the permanent memory the intermediate memory is released again. After release of the intermediate memory the feeding of individual value documents and capturing and storing of measuring data for the fed value documents in the intermediate memory is restarted.
