Related SC Codes

One of two SC codes is issued if the proximity sensor (human detection sensor) fails.
SC869-01 Proximity sensor (human detection 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 (human detection 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 (human detection sensor) with the User Tool
setting described above.
• The sensor and its components require replacement.
SC869-02 Proximity sensor (human detection 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 cover, 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 (human detection sensor) with the User Tool
setting described above.
