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: 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 RTC backup battery voltage fall
Causes: Battery life Battery circuit abnormality
Remedy: Check to confirm that the battery voltage is about 2.5V or above. Replace the battery.
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: Erroneous detection of account management data
Causes: Breakage of the authentication DB is detected.
Remedy: When breakage of the authentication DB is detected, the MFP is rebooted and the DB tables are reconstructed, generating "U2-05". The message, however, is not displayed and only the trouble history is saved. The authentication data are cleared.
Code: U2-11
Description: MFPC PWB EEPROM counter check sum error
Remedy: 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.)
Code: U2-30
Description: MFPC PWB and PCU PWB manufacturing No. data inconsistency Inconsistency between the manufacturing No. saved in the PCU PWB and that in the MFPC PWB.
Causes: When replacing the PCU PWB or the MFPC PWB, the EEPROM which was mounted on the PWB before replacement is not mounted on the new PWB. MFPC PWB trouble PCU PWB trouble
Remedy: Check that the EEPROM is properly set. Check to confirm that the EEPROM which was mounted on the PWB before replacement is mounted on the new PWB. 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.) Replace the PCU PWB.
