Sensors are the most part of an ATM machine. They are responsible for keeping in check the bills that are supposed to get automated from the ATM machine. ATM error occurring in the CS14 sensor is important because in case the notes that are dispensed have any sort of issue such as let us say if it was torn, worn out, or crumbled, then this CS14 sensor shows the ATM error code d0111 on the display screen. The bills that are not suitable to get transacted are diverted back and sent to the ‘reject bin’. If the reject rate is high, then the machine owner is informed to clean, repair, or in some cases change the dispensing machine.
