• Code: E074-0003
• Description: Error in Sensor
  Both Primary Transfer Detachment Sensor 1 and 2 (PS22,PS23) are detected at the time of engagement/ disengagement operation
• Remedy: 1. Check connection of the connector with the ITB Unit. 2. Replace the Primary Transfer Detachment Sensor 1 and 2 (PS22,PS23)

• Code: E075-0002
• Description: Timeout error in searching ITB steering HP
  Unable to detect change (Low -> High or High -> Low) of ITB Steering Sensor Signal although 10 sec has passed.
• Remedy: 1. Check if the ITB Connector is physically removed. 2. Check if the cable of the ITB Unit is open circuit (including the inside of the ITB Unit). 3. Replace the ITB Displacement Control Motor (M14) and its Drive Assembly (the gear, Drive Shaft, Mounting Plate, etc.). 4. Replace the DC Controller PCB (UN1).

• Code: E075-0003
• Description: Error in full displacement of ITB (rear)
  ITB Displacement Sensor detects full displacement position at the rear.
• Remedy: 1. Correct the displacement of the ITB. (Procedures are shown below.) 2. Replace the ITB. 3. Replace the Secondary Transfer Roller. a) Place paper and remove the ITB Unit. b) Lift the front left side up (where the Cleaner and Motor are located) and hold the ITB Unit as if to twist it. c) Turn the Motor counterclockwise as if to make 2 to 3 rounds of the ITB. d) As the ITB is getting closer to the center, align the edge of the ITB with the marking line. NOTE: This symptom is likely to occur if the machine is not installed on the level (the left-rear is higher). Check if the machine is installed on the level. If this symptom still occurs, perform steps 2 and 3.

• Code: E075-0004
• Description: Error in combination of ITB Displacement Sensors
  Failed to determine position due to combination of the ITB Displacement Sensors (PS25 - PS28) (faulty sensor)
• Remedy: 1. Check if the ITB Connector is physically removed. 2. Check if the cable of the ITB Unit is open circuit (including the inside of the ITB Unit). 3. Replace the ITB Displacement Control Motor (M14) and its Drive Assembly (the gear, Drive Shaft, Mounting Plate, etc.). 4. Replace the DC Controller PCB (UN1).

• Code: E075-0005
• Description: Error/failure in searching ITB steering HP
  Failed to detect correct HP position although the change (Low -> High or High -> Low) of the ITB Steering Sensor Signal can be detected (execute retry twice)
• Remedy: 1. Check if the ITB Connector is physically removed. 2. Check if the cable of the ITB Unit is open circuit (including the inside of the ITB Unit). 3. Replace the ITB Displacement Control Motor (M14) and its Drive Assembly (the gear, Drive Shaft, Mounting Plate, etc.). 4. Replace the DC Controller PCB (UN1).

• Code: E075-0006
• Description: Timeout error in searching ITB equilibrium position
  The equilibrium position could not be found although 11 minutes have passed when searching ITB equilibrium position.
• Remedy: 1. Turn OFF and then ON the power. 2. Replace the Secondary Transfer Inner Roller. 3. Replace the ITB Unit.

• Code: E075-0007
• Description: Interruption error in searching ITB equilibrium position
  Door open was detected while executing COPIER>FUNCTION>MISC-P>ITB-INIT.
• Remedy: After turning OFF and then ON the power, execute COPIER>FUNCTION>MISC-P>ITB-INIT, and check that OK is displayed.

• Code: E075-0103
• Description: Error in full displacement of ITB (front)
  ITB Displacement Sensor detects full displacement position at the front.
• Remedy: 1. Correct the displacement of the ITB. (Procedures are shown below.) 2. Replace the ITB. 3. Replace the Secondary Transfer Roller. a) Place paper and remove the ITB Unit. b) Lift the rear left side up (where the cleaner is located; opposite to the motor) and hold the ITB Unit as if to twist it. c) Turn the Motor counterclockwise as if to make 2 to 3 rounds of the ITB. d) As the ITB is getting closer to the center, align the edge of the ITB with the marking line. NOTE: This symptom is likely to occur if the machine is not installed on the level (the left-front is higher). Check if the machine is installed on the level. If this symptom still occurs, perform steps 2 and 3.
