Could someone please comfirm where the location is of the PCB2 board on a Canon IRA C2225?
I believe it is the middle board - the one that the hard drive plugs into....but in any case please reassure me before I replace the wrond thing!
Thank you

Removing the Main Controller 2--see attachment pdf
1) Backup of the Forwarding Settings and Service Mode setting values (MN-CON)
Use the Remote UI.
Management Settings > Data Management > Import/Export
Target data:
• Forwarding Settings
• Service Mode setting values (MN-CON)
Only when ON is selected in COPIER > OPTION > USER > SMD-EXPT, the service
mode setting values can be backed up and restored from the RUI.


Preparation
1) Remove the Rear Upper Cover.
2) Remove the Right Upper Sub Cover.
3) Remove the Controller Cover.
Procedure
1) Remove the 5 Connectors, 3 Flat Cables, Edge Saddle and Wire Saddle.
• 5 Connectors
• 3 Flat cables
• Wire Saddle
• Edge Saddle
2) Remove Main Controller PCB 2 in the direction of the arrow.------->
• 5 Screws


1) After installing the parts, turn ON the main power switch.
2) Restoring the backup data
Use the Remote UI.
Management Settings > Data Management > Import/Export
3) TPM key information
If the TPM key information in the SRAM of the HDD or the Main Controller PCB 2 is lost, the key information in the SRAM is automatically recovered from the backup of
the common key in the HDD. Then the internal state of TPM setting changes to "ON".
However, the display on the UI remains "OFF", therefore the TPM setting needs to be manually changed to "ON".
4) When the user generates and adds the encryption key, certificate and/or CA certificate, request the user to generate them again
