2. Handling of EEPROM
A. Note for the handling of EEPROM
WARNING: Never execute Sim16 to clear U2 trouble WITHOUT investigating the root cause of U2 trouble using the following note.
1)
Make sure to put an earth band while handling PWB. EEPROM data may be garbled due to the static charge.
(It is mentioned in Note for Serving.)
(It is mentioned in Note for Serving.)
2)
Never to insert EEPROM to the socket in reverse.
U2 trouble occurs 100% if the machine is turned on after inserting the EEPROM in reverse.
Execution of Sim16 to clear this U2 trouble will lead to the garbled data.
Data won’t recover once the data is garbled.
3)
Make sure that PCU, MFP, SCAN EEPROMs won’t be switched.
U2 trouble occurs 100% if the machine is turned on while the EEPROMs are being switched.
Execution of Sim16 to clear this U2 trouble will lead to the garbled data. Data won’t recover once the data is garbled.
To prevent such troubles, put a mark such as “MFP” to each EEPROM before removing from PWB so that it is easy to distinguish.
4)
Please handle EEPROMs with care to prevent bending of pins.
They will be broken if bent several of times. (This type of trouble has been reported many times.).
5)
Do not use foamed styrol etc. for packing during the transportation of EEPROM.
Foamed styrol easily generates static charge. In some cases, EEPROM is damaged just by sticking it into foamed styrol.
Make sure to use the black sponge for packing during transportation. The black sponge is used to pack EEPROM provided as service
parts.
parts.
Special material is used for this black sponge so that it won't generate a static charge.
CAUTION: Please note that counter data and machine adjustment values are recorded in the EEPROM.
If the data in EEPROM is garbled, it is impossible to recover.
In such cases, the only solution will be the initialization of the EEPROM.
Counter data and adjustment values will be reset to “0” or “default” once the data are initialized.
Once all the adjustment values are set to default, it will be necessary to readjust all the adjustment values, which requires tremen-
dous workload.
dous workload.
B. Caution to prevent damage on EEPROM
- In case any trouble other than U2 trouble occurs to the machine, replace PWB (remove and install EEPROM) to fix, and U2 trouble occurs
right after power on, never execute Sim16 under the condition.
As previously mentioned, the data in EEPROM will be garbled after the execution of Sim16.
- In such cases, EEPROM may have been inserted in reverse or MFP and PCU EEPROM may have been switched.
- Turn off the machine without execution of Sim16, install proper EEPROM in proper position (on PWB), turn on the machine again, and then
execute Sim16. This way U2 error will be cleared.
- Sim16 is executed to clear U2 errors if it occurred without performing any services (such as machine repair or maintenance).
As previously mentioned, execution of Sim16 won’t clear artificially-generated U2 errors. Instead, it actually damages the EEPROM.HDD

3. Necessary steps when replacing the PWB, HDD, SD Card and the CF card
A. MFP substrate replacement procedure (work flow)
CAUTION: Registered user information will not be recovered if the MFP PWB is affected by U2-05 trouble. (*1)
1)
Attach the flash ROM, the memory, the EEPROM, the SD card etc. of the MFP PWB on the service parts MFP PWB and install it to the
main unit.
main unit.
CAUTION: Ground your body with grounding band during the work.
2)
When U2 trouble occurs, use SIM16 to cancel it.
3)
Set as follows after restarting the main unit.
At this timing, F6-21 may occur. Whether it may occur or not, go to execute procedure 1.
(1) Set the appropriate country code by Sim66-02 (clear the software switches related to FAX).
CAUTION: Make sure to execute even if the fax option is not installed on the machine.
B. Procedures necessary for HDD replacement
Note for HDD replacement
- Data of the following list are saved in the HDD of the complex machine. If the HDD operates normally and data backup is possible before
replacement, perform data backup and then replace the HDD.
- If the HDD does not operate normally, data cannot be backed up.
- The HDD replacement procedures with a broken HDD differs from that with a normal HDD.
