• Code: 009-660
• Description: Environmental Sensor Temperature An incorrect value was detected by the Environmental Sensor (Temperature).
• Remedy: Disconnect J255. There is 1 Ohm or less measured between P255-3 and P255-4 on the Environment Sensor. Y↓N→Replace the Environment Sensor (PL 1.3). Replace the I/F PWB (PL 9.1) and Engine Control Board (MCU PWB) (PL 13.1) in sequence.

• Code: 009-661
• Description: Environmental Sensor Temperature An incorrect value was detected by the Environmental Sensor (Temperature).
• Remedy: There is +0.4 VDC to +17 VDC from J404-11 on the MCU PWB to GND. Y↓N→There is +5 VDC from J404-12 on the I/F PWB to GND. Y↓N→Check the wires and connectors. If the check is OK, replace the Engine Control Board (MCU PWB) (PL 13.1). Check for an open circuit and poor contact. If the check is OK replace the Environment Sensor (PL 1.3). Replace the I/F PWB (PL 9.1). If the problem continues, replace the Engine Control Board (MCU PWB) (PL 13.1).

• Code: 009-670
• Description: New Black Toner Cartridge Detected The control logic detected that the Toner Cartridge has been replaced. This is a message fault only.
• Remedy: Turn the printer power Off, then On. The message fault clears. Y↓N→Go to RAP 009-390, New Black Toner Cartridge. Return to Service Call Procedures.

• Code: 009-671
• Description: New Cyan Toner Cartridge Detected The control logic detected that the Toner Cartridge has been replaced. This is a message fault only.
• Remedy: Turn the printer power Off, then On. The message fault clears. Y↓N→Go to RAP 009-391, New Cyan Toner Cartridge. Return to Service Call Procedures.

• Code: 009-672
• Description: New Magenta Toner Cartridge Detected The control logic detected that the Toner Cartridge has been replaced. This is a message fault only.
• Remedy: Turn the printer power Off, then On. The message fault clears. Y↓N→Go to RAP 009-392, New Magenta Toner Cartridge. Return to Service Call Procedures.

• Code: 009-673
• Description: New Yellow Toner Cartridge Detected The control logic detected that the Toner Cartridge has been replaced.This is a message fault only.
• Remedy: Turn the printer power Off, then On. The message fault clears. Y↓N→Go to RAP 009-393, New Yellow Toner Cartridge. Return to Service Call Procedures.

• Code: 009-684
• Description: ADC Shutter Fail The control logic detected an ADC Shutter operation failure.
• Remedy: Enter Service Diagnostics Menu: Printer Menu > Troubleshooting > Service Tools > Printer Status Page > hold the Up and Down buttons simultaneously > Run Service Diagnostics > OK. Perform the ADC Solenoid tests. The ADC Shutter Solenoid energized. Y↓N→There is +24 VDC from J404B-2 on the MCU PWB to GND. Y↓N→Check the wires and connectors. If the check is OK, replace the I/F PWB (PL 9.1). If the problem continues, replace the ADC Sensor (PL 1.3). There is 0 VDC from J404B-3 on the MCU PWB to GND. Y↓N→Check the wires and connectors. If the check is OK, replace the I/F PWB (PL 9.1). If the problem continues, replace the MCU PWB (PL 13.1). If the problem continues, replace the ADC Sensor (PL 1.3). The voltage from J404B-1 on the MCU PWB to GND changed to 0VDC momentarily. Y↓N→Check the wires and connectors. If the check is OK, replace the I/F PWB (PL 9.1). If the problem continues, replace the Engine Control Board (MCU PWB) (PL 13.1). If the problem continues, replace the ADC Sensor (PL 1.3). Check the wires and connectors. If the check is OK, replace the ADC Sensor (PL 1.3). After checking that no failures are detected during normal operation, go to call closeout.

• Code: 009-695
• Description: Failure Position Judgement Position Judgement Failure.
• Remedy: Turn the printer power Off, then On. If the problem continues, call service support for assistance.
