Error Code 351
Error Code 351: MODULE NEEDS SERVICE
1. Use the diagnostic functions or NMD test software to determine if a note feeder has a faulty or dirty sensor.
2. Remove each note feeder module from the dispensing mechanism and clean their associated empty, pressure, and exit sensors with clean compressed air. Install the note feeders and recheck their operation to determine if the error code has been cleared.
3. If the error code has been cleared, the ATM can be put back in service. If the error code is repeated, replace the note feeder or note feeder controller for the affected feed channel.
