3) Error 'Fusing unit not compatible' problem

Symptom : Error 'Fusing unit not compatible' happens.

Cause : Harness for EEPROM signal is damaged by the sharp edge of the Fuser frame.

Troubleshooting

1) Check if the EEPROM signal harness is damaged.

If so, replace the fuser unit (from 2015.08.11 the new part was applied) or insulate the damaged spot of harness

by wrapping each harness up.

You may need to remove the pre-existing AT tape, and re-apply the insulation for damaged each harness.

New design was applied from 2015.08.11 which doesn't have the sharp edge on the harness path.
