CHAPTER 5 MAINTENANCE MENUS
Replacement of EEPROM after replacement of TBH PCB
The EEPROM of the TBH 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.
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
• The CU Serial Number is a 10-digit number excluding the two digits for Revision from
the 12 of the SAP Serial Number.
• 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 Serial Number only"
(Default setting).
• To specify the CU Serial Number, enter a 10-digit number (Notice that, when the CU
Serial Number is read, it is also a 10-digit number.)
