摘要： The invention relates to a sensor for verifying various features of value documents, said sensor performing a self-test to check the operability thereof. Prior to the sensor performing the self-test, at least one of the features to be verified by the sensor is selected. In the self-test, the sensor assesses a malfunction identified during the self-test differently according to the selected feature and reacts differently to the identified malfunction. A malfunction of the sensor used to consistently result in the sensor being down, while the sensor of the invention can still verify certain features in spite of an identified malfunction. The different reactions of the sensor to the identified malfunction according to the selected feature result in a reduction in the number of failures of the sensor.
