2. When access to the EEPROM of the board to remove is impossible.
If the SERVICE CALL 104 [Engine EEPROM Error] or 40 [EEPROM Error] is
displayed on the operator panel with the board to remove, or is EEPROM data
cannot be read-out, perform the following procedure by using the Maintenance

(1) Setting the serial number information (Maintenance Utilities Operation
Manual section 2.4.1.1.10.3)
The SAP serial number is applied to printer. The SAP serial number is
displayed in the top-most row of the serial number label. Its number indicates
the production place with 2 digits, manufacture date with 2 digits, serial
number (sequential number) with 6 digits and revision number with 2 digits
totaling 12 digits number.
• Select PU Serial Number for the printer serial number, and Show Only Serial
Number for the output mode. Do not enter the CU serial number.
• The PU serial number is the 10 digits number excluding the revision number of 2
digits among the 12 digits SAP serial number.
• Perform the above setting by using the Maintenance Utilities section "2.4.1.1.10
Board setting function" – section "2.4.1.1.10.3 Serial number information setting".
• To specify the PU serial number, enter the 11 digits number after adding "0" (Zero
in single-byte character) at the top. (Be careful that the read-out data shows the 10
digits number.)
Enter the 11 digit number by adding "0" (Zero in single-byte character) before the
10 digit number excluding the revision 2 digits that is shown in conceptual drawing
