2. When access to the EEPROM of the board to remove is impossible:
If the SERVICE CALL 104 (Engine EEPROM Error) is displayed on the operator
panel with the board that user is going to remove, or is EEPROM data cannot
be read-out, perform the following procedure by using the Maintenance Utilities.
(1) Setting the PU serial number
(Maintenance Utilities Operation Manual section 2.4.1.2 PU board setting)
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 digit number.
•
The PU serial number is the 10 digit number excluding the revision number of 2
digits among the 12 digit SAP serial number.
•
Perform the above setting by using the Maintenance Utilities section "2.4.1.1.2 PU
board setting function" – section "2.4.1.1.2.1 PU serial number setting".
•
To specify the PU serial number, enter the 11 digit number after adding "0" (zero in
single-byte character) at the top. (Be careful that the read-out data shows the 10
digit 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
of "PU serial number setting" screen as shown below.
The adjustments that are required upon completion of part replacement are described
below.

5.4.1 Precautions when replacing the engine control board
1. When access to the EEPROM of the board to remove is possible:
(When the SERVICE CALL 104 [Engine EEPROM Error] is not displayed:)
(1) Obtain the EEPROM information from the board that user is going to be
removed, by using the PU board replacement function (Maintenance Utilities
Operation Manual section 2.4.1.1.1 PU board replacement function) of the
Maintenance Utilities, and save it in the hard disk of PC temporarily.
(2) Copy the EEPROM information that has been saved in the hard disk of PC by
step (1), into the EEPROM of the new replacement board by using the PU
board replacement function (Maintenance Utilities Operation Manual section
2.4.1.1.1 PU board replacement function) of the Maintenance Utilities.
Note!
When obtaining and copying the EEPROM information by using the
Maintenance Utilities, set the printer into the "Forced ONLINE mode" by
following the procedure described below. If the printer is in the error state,
the error display is issued even during the forced ONLINE mode.
1. When turning on the printer power, keep pressing [BACK] + [MENU-] +
[ENTER] until "STATUS MODE" is displayed on the operator panel.
2. If the printer is normal, "ON LINE" display is shown. If the printer has
an error, the error display is shown. However, the printer has entered
the ON LINE state in which communication is enabled.
•
The PU serial number is output to the Printer Serial Number column of the Menu
Map header portion. Therefore, confirmation upon completion of rewriting the PU
serial number can be performed by printing the Menu Map.
Enter the 11 digit number after adding “0” (zero in single-byte character)
before the 10 digit number. (Enter “OAEO1234567”.)
