Code :

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

Code: U1-01
Description: Battery trouble
Causes: 1) Battery life 2) Battery circuit abnormality
Remedy: Check to confirm that the battery voltage is about 2.5V or above. Replace the battery.

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.
