• Code: E066-0001
• Description: Pre-transfer Charging Wire Shutter HP open error. The Pre-transfer Charging Wire Shutter HP Sensor (PS93) detected that the shutter was open although it was moved to the close position.
• Remedy: 1. Check connection of the Pre-transfer Charging Wire Cleaning Motor (M2). 2. Replace the Pre-transfer Charging Wire Cleaning Motor (M2). 3. Check connection of the Pre-transfer Charging Wire Shutter HP Sensor (PS93). 4. Replace the Pre-transfer Charging Wire Shutter HP Sensor (PS93). 5. Check shutter mechanism of the Pre-transfer Charging Assembly. 6. Replace the Pre-transfer Charging Assembly. 7. Replace the DC Controller PCB.

• Code: E066-0002
• Description: Pre-transfer Charging Wire Shutter HP close error. The Pre-transfer Charging Wire Shutter HP Sensor (PS93) detected that the shutter was closed although it was moved to the open position
• Remedy: 1. Check connection of the Pre-transfer Charging Wire Cleaning Motor (M2). 2. Replace the Pre-transfer Charging Wire Cleaning Motor (M2). 3. Check connection of the Pre-transfer Charging Wire Shutter HP Sensor (PS93). 4. Replace the Pre-transfer Charging Wire Shutter HP Sensor (PS93). 5. Check shutter mechanism of the Pre-transfer Charging Assembly. 6. Replace the Pre-transfer Charging Assembly. 7. Replace the DC Controller PCB.

• Code: E066-0011
• Description: Primary Charging Wire Shutter error 1 when cleaning the Pre-transfer Charging Wire. The Pre-transfer Charging Wire Shutter HP Sensor (PS93) failed to be detected although 10 seconds have passed since the Pre-transfer Charging Wire Shutter started its operation
