Code :

Code: U2-00
Description: MFP EEPROM read/write error
Causes: EEPROM device trouble EEPROM device contact trouble Device access trouble by the noise
Remedy: Replace the SCN-MFP PWB EEPROM. Replace the SCN-MFP PWB. (Refer to the pages on the necessary works after replacing the SCN-MFP PWB in the Service Manual, and perform the works.) Check that the EEPROM device is connected correctly.

Code: U2-05
Description: Account data error
Causes: The certification database table in the HDD is broken. The certification database table is rebuilt after the broken certification database table is detected and the main unit is restarted. This error can be recognized only by the SIM22-4 which registers the error in the error records. When this error is occurred frequently, the following devices are defective. - HDD - SCN-MFP PWB
Remedy: Check or replace the HDD. Check or replace the SCN-MFP PWB. Perform the operation by referring the "Necessary works and procedures when the HDD and the SCNMFP PWB are replaced". When this error is not occurred frequently, the above operations should not be done.

Code: U2-11
Description: SCN-MFP PWB EEPROM counter check sum error
Causes: SCN-MFP PWB EEPROM trouble EEPROM socket contact trouble SCN-MFP 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 SCN-MFP PWB. (Refer to the pages on the necessary works after replacing the SCN-MFP PWB in the Service Manual, and perform the works.)

Code: U2-30
Description: SCN-MFP PWB and PCU PWB manufacturing No. data inconsistency
Causes: When replacing the SCN-MFP PWB or the MFPC PWB, the EEPROM which was mounted on the PWB before replacement is not mounted on the new PWB. SCN-MFP 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 SCN-MFP PWB. (Refer to the pages on the necessary works after replacing the SCN-MFP PWB in the Service Manual, and perform the works.) Replace the PCU PWB.

Code: U2-40
Description: mSATA SSD system storage data partition error
Causes: A file error occurs in the mSATA SSD system storage data partition.
Remedy: Turn OFF/ON the power, and the backup data in the HDD are written into the mSATA SSD and the machine is automatically booted.

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.)
