1.  Using a PC, copy the Watermark Update firmware 

onto the root of a USB memory device:- 

Caution:  
When copying the Watermark firmware and 
directories onto the USB drive, do not change the 
folder hierarchy or files. 

 

 

 

2.  Insert the USB memory device into a USB port on 

the machine and execute Simulation 49-05 
[WATER MARK UPDATE]:- 

 

Note:  
If no USB device is detected, an error message will 
be displayed. 

 

 

 

3.  Select the Directory containing the Watermark 

update files:- 

 

Note: 
The Watermark firmware is common across  
MX-M904/1054/1204 & MX-M1055/1205. 

 

 

 
 
 

4.  The current and updated version should now be 

displayed. Press Execute to commence upgrade:- 

 

 

 

5.  Update File Checking and a progress of the update 

will be displayed:- 

 

 

 

6.  Once the update is complete, press OK to exit 

simulation mode. 

 
 

Watermark Update is complete.

WARNING:  
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. 

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. 

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. 

  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.

Most data that is stored on the HDD can be backed up and reinstalled following replacement or HDD failure. 
If the HDD is operating normally before replacement, backup the data and then reinstall the data onto the 
replacement HDD. 

 

The HDD contains the following data:- 

 

No.

1.  Back up the HDD storage data before replacement:- 

 

  Use SIM56-02 or device cloning/storage backup function to back up the Address book, Image 

Send registration data and User authentication data to USB memory. 

 

  When using the MFP Web Page, back up the Document Filing data, Font, Macro and JOB LOG data 

to PC 

 

2.  When there is Internet Fax received data present, use SIM66-62 to back up the image data to USB 

memory (PDF file), and then provide the PDF data to the user. (This data cannot be restored to the 
machine). 

 

3.  Replace the HDD. 

 

4.  Power on / Boot the MFP Device:- 

 

  For new HDD (from service parts) only, Formatting is automatically performed. 

 

  When using an HDD from another MFP Device, U2-05 trouble will be displayed. Use SIM16 to 

cancel U2-05 trouble and then format the HDD using SIM62-01. 

 

5.  Clear the IMAGE SEND image data by executing SIM66-10:- 

 

 

6.  Install the E-Manual Data onto the HDD using SIM49-03. 

 

7.  Install Watermark data onto the HDD using SIM49-05:- 

 

 

8.  Import the storage data backed up in Step 1. 

 

  Use SIM56-02 or device cloning/storage backup function to import the Address book, Image Send 

registration data and User authentication data etc. 

 

  Import the Document Filing data, User font and macro data - (The JOB LOG data can be backed up 

but cannot be imported).
