• Code: P1-01
• Description: PCI fan error
• Causes: The PCI fan operation signal is not detected. PCI fan trouble. PCI control PWB trouble.
• Remedy: Check connection of the connectors and harness between the PCI fan and the PCI control PWB. Check the PCI control PWB, and replace if necessary. Check the PCI fan, and replace if necessary.

• Code: P1-02
• Description: Plasma generating device error
• Causes: Connection failure of connectors and harness between the plasma generating device and the PCI control PWB. Plasma generating device trouble. PCI control PWB trouble.
• Remedy: Check connection of the connectors and harness between the plasma generating device and the PCI control PWB. Replace the plasma generating device. Check the PCI control PWB, and replace if necessary.

• Code: PC--
• Description: Personal counter not detected
• Causes: The personal counter is not installed. The personal counter is not detected. SCU PWB trouble.
• Remedy: Check connection of the connectors and the harness. Replace the SCU PWB.

• Code: U1-01
• Description: Battery trouble
• Causes: 1) Battery life 2) Battery circuit abnormality

• Code: U2-00
• Description: MFP EEPROM read/write error
• Causes: MFPC PWB EEPROM trouble EEPROM socket contact trouble MFPC PWB trouble Strong external noises.
• Remedy: Replace the MFPC PWB EEPROM. Replace the MFPC PWB. (Refer to the pages on the necessary works after replacing the MFPC PWB in the Service Manual, and perform the works.) Check the power environment.

• Code: U2-05
• Description: SD/MFPC PWB SRAM contents inconsistency
• Causes: The SD card was replaced. The MFPC PWB was replaced. SD card trouble MFPC PWB trouble
• Remedy: Refer to the pages on the necessary works after replacing the SD and the MFPC PWB in the Service Manual, and perform the works. Use SIM16 to cancel the error.

• Code: U2-10
• Description: MFPC PWB SRAM user authentication index check sum error
• Causes: SRAM user index information (user authentication basic data) check sum error. MFPC PWB SRAM trouble. MFPC PWB trouble. Strong external noises.
• Remedy: Use SIM16 to cancel the error. (Index information data in the HDD are transferred to the SRAM.) Replace the MFPC PWB. (Refer to the pages on the necessary works after replacing the MFPC PWB in the Service Manual, and perform the works.)

• Code: U2-11
• Description: MFPC PWB EEPROM counter check sum error
• Causes: MFPC PWB EEPROM trouble EEPROM socket contact trouble MFPC PWB trouble Strong external noises.
• Remedy: Use SIM16 to cancel the error. (The previous writing data (about the latest 8 sheets) are written into the EEPROM.) Replace the MFPC PWB. (Refer to the pages on the necessary works after replacing the MFPC PWB in the Service Manual, and perform the works.)
