One of two SC codes is issued if the proximity sensor fails.
SC869-01 Proximity sensor failure: Error 1.
The sensor remained on for over 24 hours.
Cycling the machine off/on does not cancel this error.
When this error occurs the machine enters sensor failure mode and ignores subsequent input from the proximity sensor.
Even though the sensor is on, the machine does not enter Pre-recovery mode, and the Engine Off timer setting is not affected and continues to operate normally.
To cancel the error, switch off the proximity sensor with the User Tool setting described above.
The sensor and its components require replacement.
SC869-02 Proximity sensor failure: Error 2
The sensor remained off, even after the operator performed 20 actions with the machine operation panel, opening and closing the front door, ADF, etc. The machine will issue this error code after every 20 events in operation of the machine.
Cycling the machine off/on does not cancel this error.
To cancel the error, switch off the proximity sensor with the User Tool setting described above.
The sensor and its components require replacement.
