Description: Machine adjustment data (system storage data area) error
Causes: The saved file of the machine adjustment values in the SD card and the HDD cannot be found or is broken. Both of the SD card set data and the HDD system saved data area are broken. HDD trouble MFPC PWB trouble SD card trouble
Remedy: Check the HDD, and replace if necessary. Check the MFPC PWB, and replace if necessary. Check the SD card, and replace if necessary. When replacing the HDD, the MFPC PWB, and the SD card, refer to the chapter of "Necessary works and procedures of HDD, MFPC PWB, and SD card replacement." Use SIM to adjust the machine again and set the adjustment values.
Code: U2-50
Description: HDD user authentication data check sum error (SD card when no HDD is installed)
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*1. Replace the MFPC PWB. (Refer to the pages on the necessary works after replacing the HDD and the MFPC PWB in the Service Manual, and perform the works.)*1 SD card when no HDD is installed.
Code: U2-60
Description: Watermark check error
Causes: Watermark data trouble HDD trouble MFPC PWB trouble
Remedy: Use SIM16 to cancel the U2 trouble. Use SIM49-5 to install the watermark data. Replace the HDD. Replace the MFPC PWB. (Refer to the pages on the necessary works after replacing the HDD and the MFPC PWB in the Service Manual, and perform the works.)
Remedy: Replace the SCU PWB EEPROM. Replace the SCU PWB. Check connection of the SCU PWB EEPROM socket. Check the SIM adjustment value of the following items, and adjust again if they are improper. • Scanner-related adjustments • Touch panel-related adjustments Use SIM16 to cancel the trouble. To avoid missing of the counter data and the adjustment values, use this simulation to save the counter data and the adjustment values. (If there is a printer option, use SIM22-01 to save the counter data and the adjustment values.)
Remedy: Replace the SCU PWB EEPROM. Replace the SCU PWB. Check contact of the EEPROM socket. Use SIM16 to cancel the trouble. (The check sum error detection data are calculated again to reset the proper check sum data.) To avoid missing of the counter data and the adjustment values, use this simulation to save the counter data and the adjustment values. (If there is a printer option, use SIM22-01 to save the counter data and the adjustment values.)
Remedy: Replace the PCU PWB EEPROM. Check the SIM adjustment values of the engine, and adjust again if they are improper. Replace the PCU PWB. Check contact of the EEPROM socket. Use SIM16 to cancel the trouble. To avoid missing of the counter data and the adjustment values, use this simulation to save the counter data and the adjustment values. (If there is a printer option, use SIM22-01 to save the counter data and the adjustment values.)
