5.4.2.1 Replacement of EEPROM after replacement of PDL CU PCB
(C6150/C6050)
The EEPROM of the PDL CU PCB is installed in the IC socket. Replace the EEPROM in the
following 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
the EEPROM 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.
5.4.2.2 Setup of CU Serial Number
The printer has a SAP Serial Number applied. The 12-digit SAP Serial Number is marked in
the top line of the serial number label, and is made up of two digits for production base, two
digits for manufacturing year and month, six digits for serial No. (Sequence No.), and two
digits for Revision.
(1) For destinations other than OEL
CU serial number setting is unnecessary.
(2) For OEL destination
• For CU Serial Number, a unique Serial Number within 12 digits is assigned at the UK
Plant.
• 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 "Subsection
2.4.1.1.4 CU PCB setup function" of the maintenance utility, set"Select Printer Serial
Number" to "CU Serial Number" and [Display Mode], to "Show Both".
5.4.2 Setup of EEPROM after replacement of CU PCB
When the CU PCB is replaced, it is necessary for the new replacement PCB to take over the user-
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, and set the CU Serial
No.(See Subsection 5.4.2.2) and check the setup of destination (See Subsection 5.4.3).
Meanwhile, in the case of the PDL CU PCB, the EEPROM can be swapped directly between a new
PCB and an old one. In this case, the CU Serial No. setup and destination setup are not required.
