Code :

Code: U2-41
Description: HDD versatile partition error
Causes: A file error occurs in the HDD system saved data area, disabling backup of the saved file of the machine adjustment values in the mSATA SSD. HDD trouble MFPC PWB trouble
Remedy: Backup the data by following the procedure for the trouble which can be released by turning OFF and ON the power of the main unit, and format the HDD by SIM62. Or, replace the HDD and perform SIM16.

Code: U2-42
Description: Machine adjustment data lost error
Causes: The system data partition of mSATA SSD and the versatile partition for the backup HDD are broken.
Remedy: Backup the data by following the procedure for the mSATA SSD and the HDD breakage and format the HDD by SIM62. Or, replace the HDD and perform SIM16. Perform the mechanical adjustment because the mechanical adjustment values are formatted.

Code: U2-50
Description: HDD user authentication data check sum error
Causes: HDD trouble SCN-MFP PWB trouble Strong external noises.
Remedy: Check the data related to the check sum error (address book, image send system registration data (senders record, meta data)) and register again. Use SIM16 to cancel the U2 trouble. Replace the HDD. Replace the SCN-MFP PWB. (Refer to the pages on the necessary works after replacing the HDD and the SCN-MFP PWB in the Service Manual, and perform the works.)

Code: U2-60
Description: Watermark check error
Causes: Watermark data trouble mSATA SSD trouble SCN-MFP PWB trouble
Remedy: Use SIM16 to cancel the U2 trouble. Use SIM49-5 to install the watermark data. Replace the mSATA SSD. Replace the SCN-MFP PWB. (Refer to the pages on the necessary works after replacing the HDD and the SCN-MFP PWB in the Service Manual, and perform the works.)

Code: U2-80
Description: SCN-MFP PWB EEPROM read/write error
Causes: EEPROM trouble SCN-MFP PWB EEPROM access circuit trouble
Remedy: Check that the EEPROM is attached correctly. Take notes of the counter data and the adjustment values to prevent from deleting the data. (When the printer option is attached, take notes of the adjustment values by SIM22-01.) Replace the PCU PWB. Release this error with SIM16.

Code: U2-81
Description: SCN-MFP PWB EEPROM check sum error
Causes: EEPROM trouble SCN-MFP PWB EEPROM access circuit trouble
Remedy: Check that the EEPROM is attached correctly. Take notes of the counter data and the adjustment values to prevent from deleting the data. (When the printer option is attached, take notes of the adjustment values by SIM22-01.) Replace the PCU PWB. Release this error with SIM16.

Code: U2-90
Description: PCU PWB EEPROM read/write error
Causes: EEPROM trouble Installation of non-initialized EEPROM. PCU PWB EEPROM access circuit trouble
Remedy: Check that the EEPROM is attached correctly. Check that the 256kBit EEPROM is attached. Take notes of the counter data and the adjustment values to prevent from deleting the data. (When the printer option is attached, take notes of the adjustment values by SIM22-01.) Replace the PCU PWB. Release this error with SIM16.
