Code COb31 means that the sorter didn't reset after a job. If you try doing a reset by opening the sorter as if there was a paper jam and it doesn't reset, it means that you have a problem with the sensors by the motor that turns the bins to open and clause as the paper passes. Give it a good blow with air. GOOD LUCK.
