[Code] C0011 [Resolution] This indicates that during a dispense, the sensor located at the front of the CDU shows a blockage (CS13 or CS2). The primary reason for this is a bill which bounces back from the cash tray (sometimes from a customers fingers). Check the front of the CDU and the cash tray for blockage. Reinitialize the ATM to put back in service. In the case of a dispute from the error, use CDU data in the journal to verify how many notes were actually dispensed. [Description]
