5. Select Firm Update Mode by using the [Menu] & [Back] keys. Using the [UP] and [DOWN] keys,
navigate and select the required firmware SFU.
Note:
Use the [OK] key when a directory name is selected to browse through to the sub folder(s) or
the [BACK] key to return to the parent folder(s).
Use the [OK] key when a directory name is selected to browse through to the sub folder(s) or
the [BACK] key to return to the parent folder(s).
6. Press [OK] to commence Firmware Update. – It may take approx. 1‐2 minutes to read the SFU file.
After reading is completed, the firmware update (writing) will commence automatically.
Note:
The abbreviated name/location of the firmware that is being updated will appear in the upper
right corner.

7. If the firmware upgrade completes successfully, RESULT OK will be displayed:‐
8. Power off the MFP and return the MFP PWB UPDATE DIP‐SW to OFF (Default):‐
9. Power ON the MFP, and confirm that the machine boots up normally.
10. Power OFF the MFP and refit both MFP PWB Cover & Rear Cabinet.

For MX‐M266/316N installed with MX‐HD14 only:
1. Using a PC, copy the Watermark Update firmware onto the root of a USB memory device:‐
Caution:
When copying the Watermark firmware/directories onto the USB drive, do not change the folder
hierarchy or files.

EEPROM HANDLING PROCEDURE

WARNING:
Never execute Sim16 to clear U2 trouble WITHOUT investigating the root cause of U2 trouble by using the
following procedure:‐
Never execute Sim16 to clear U2 trouble WITHOUT investigating the root cause of U2 trouble by using the
following procedure:‐
1. Ensure to follow ESD procedures (using an earth strap) while handling the PWBs as EEPROM data
may become corrupted due to static charge.
2. Never insert the EEPROM to the socket in reverse.
3. 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 corrupted data which cannot be fully
recovered in the field.
recovered in the field.
4. Make sure that PCU, MFP & SCAN EEPROMs are not switched ‐ label each EEPROM for
identification purposes before removing from the PWB.
5. Please handle EEPROMs with care to prevent bending or damage of pins. They will be broken if
bent several times. (This type of trouble has been reported many times.).
6. 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 placing it into foamed
styrol.
styrol.
7. Make sure to use black sponge (anti‐static) for packing during transportation. The black sponge is
also used to pack EEPROM provided as service parts.
CAUTION:
Please note that counter data and machine adjustment values are recorded in the EEPROM. If the data in
EEPROM is corrupted, it is impossible to recover. In such cases, the only solution will be to initialise the
EEPROM therefore, counter data and adjustment values will be reset to “0” or “default”. Once all the
adjustment values are set to default, it will be necessary to readjust all the adjustment values (ie. perform
a complete run‐up procedure).
Caution to prevent damage on EEPROM:
In case any trouble other than U2 occurs to the machine and the PWB has been replaced (eg. remove and
reinstall the EEPROM onto the replacement PWB for example) and U2 trouble occurs right after power on,
never execute Sim16 under this condition.

As previously mentioned, the data in EEPROM will be corrupted after Sim 16 execution therefore:‐
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 the correct EEPROM into the proper
position (on the PWB), power on the machine again and then execute Sim16. This way, U2 trouble
should be cleared.
should be cleared.
Sim16 should only be executed to clear U2 trouble if it occurred without performing any repair or
maintenance as such.
As previously mentioned, execution of Sim16 won’t clear artificially‐generated U2 errors. Instead, it may
actually damage the EEPROM, HDD storage and backup data.
