Oki Data CONFIDENTIAL44158801TH Rev.2 191 /6.4.2 Setup of EEPROM after replacement of TBR PCBWhen the TBR PCB is replaced, it is necessary for the new replacement PCB to take over theuser-settings that the user has been using to that point, as well as the font install information.For this, copy the EEPROM by the Maintenance Utility, and set up the CU Serial No. However,if SERVICE CALL 40 is issued and the old EEPROM cannot be used, use the new PCB, andset the CU Serial No.(See Subsection 6.4.2.2) and check the setup of destination (See Sub-section 6.4.3).Meanwhile, in the case of the TBR PCB, the EEPROM can be swapped directly between a newPCB and an old one. In this case, the CU Serial No. setup and destination setup are not required.6.4.2.1 Replacement of EEPROM after replacement of TBR PCBThe EEPROM of the TBR PCB is installed in the IC socket. Replace the EEPROM in thefollowing manner:1. Remove the EEPROM and MAC address sticker label attached to the new PCB.2. Insert a flat-tipped screwdriver in between the EEPROM of the old PCB and the IC socket,and take out the EEPROM, seeing to it that the leads of the EEPROM are not bent.3. Install the EEPROM in the new PCB. In this operation, make sure that the silk print of theEEPROM and that of the PCB match in the same direction.4. Remove the MAC address sticker label of the old PCB, and paste it to the new PCB.EEPROMMAC address label6.4.2.2 Setup of CU Serial NumberThe printer has a SAP Serial Number applied. The 12-digit SAP Serial Number is marked inthe top line of the serial number label, and is made up of two digits for production base, twodigits for manufacturing year and month, six digits for serial No. (Sequence No.), and two digitsfor Revision.(1) For destinations other than OELCU serial number setting is unnecessary.(2) For OEL destination• For CU Serial Number, a unique Serial Number within 12 digits is assigned at the UKPlant.• Notice that, when the CU Serial Number is set, the menu settings inside the CU are reset(restored to the default settings). (See the Maintenance Utility Operation Manual.)• On "Subsection 2.4.1.1.4.3 Serial Number information setup screen" of "Subsection2.4.1.1.4 CU PCB setup function" of the maintenance utility, set"Select Printer SerialNumber" to "CU Serial Number" and [Display Mode], to "Show Both".
