Description ITB Displacement Sensor detects full displacement
position at the rear.
Remedy 1. Correct the displacement of the ITB.
2. Execute COPIER> FUNCTION> MISC-P> ITB-INIT.
If the value displayed in COPIER> DISPLAY> MISC>
ITB-POS is out of the range of appropriate reference
values, perform ITB alignment adjustment.
3. Replace the ITB Unit.
NOTE:
This symptom is likely to occur if the machine is not
installed on the level (the left-rear is higher). Check if the
