Code :

Code: PC---
Description: Personal counter not installed
The personal counter is not installed.
Causes: The personal counter is not installed.
Remedy: Install the personal counter.

Code: U2-00
Description: EEPROM read/write error (MFP detection)
EEPROM device read/write error
Causes: EEPROM device trouble EEPROM device contact failure Device access error due to electrical noises
Remedy: Case 1 Cause EEPROM device trouble Check and remedy Replace the EEPROM device. Case 2 Cause EEPROM device contact failure Check and remedy Check that EEPROM device is properly inserted. Case 3 Cause Device access error due to electrical noises Check and remedy Replace the MFPcnt PWB.

Code: U2-05
Description: HDD/Flash/EEPROM data discrepancy
A HDD or Flash memory for user authentication different from that used before turn off the power is installed.
Causes: Initialize the authentication information with SIM16, and import the backup data (exported data) if any.
Remedy: Initialize the authentication information with SIM16, and import the backup data (exported data) if any.

Code: U2-10
Description: SRAM user authentication index check sum error
User index information (basic data of user authentication) check sum error on the SRAM
Causes: 1) SRAM trouble 2) Hang-up of the control circuit due to electrical noises 3) MFPcnt PWB SRAM access circuit trouble
Remedy: Use SIM16 to cancel U2 trouble.

Code: U2-11
Description: EEPROM check sum error (MFP detection)
Counter information check sum error on the EEPROM
Causes: 1) EEPROM device trouble 2) EEPROM device contact failure 3) Device access error due to electrical noises
Remedy: Use SIM16 to cancel U2 trouble.

Code: U2-22
Description: SRAM memory check sum error
MFPcnt PWB SRAM memory check sum error
Causes: SRAM trouble Control circuit hang-up due to electrical noises MFPcnt PWB SRAM access circuit trouble
Remedy: Case 1 Cause SRAM trouble Check and remedy 1) Initialize the communication management table registered in SRAM and the FAX soft switch. 2) Since the registered contents have been deleted, register them again. Case 2 Cause Control circuit hang-up due to electrical noises Check and remedy Use SIM16 to cancel U2 trouble. Case 3 Cause MFPcnt PWB SRAM access circuit trouble Check and remedy Replace the MFPcnt PWB.

Code: U2-23
Description: MFPC section SRAM memory individual data check sum error
MFPcnt PWB SRAM memory individual data check sum error (Communication management table, sender registration data, etc.)
Causes: SRAM trouble Control circuit hang-up due to electrical noises MFPcnt PWB SRAM access circuit trouble
Remedy: Case 1 Cause SRAM trouble Check and remedy 1) Turn OFF/ON the power to initialize the data related to the check sum error automatically. 2) Since the registered contents have been deleted, register them again. Case 2 Cause Control circuit hang-up due to electrical noises Check and remedy Use SIM16 to cancel U2 trouble. Case 3 Cause MFPcnt PWB SRAM access circuit trouble Check and remedy Replace the MFPcnt PWB.
