5.14.1 Precautions when replacing the engine control PCB
1. In the case when access to the EEPROM of the PCB that is going to be
removed is possible.
(When SERVICE CALL 104 [Engine EEPROM Error] is not displayed.)
(1) Obtain the information from the EEPROM of the PDB that is going to be
replaced by using the PU PCB replacement function (Maintenance Utilities
Operation Manual item 2.4.1.1.1, PU PCB Replacement Function) of the
Utilities. Store the obtained information of EEPROM in the HDD of PC
temporarily.
(2) Copy the EEPROM information tat is obtained and stored by using the PU PCB
replacement function (Maintenance Utilities Operation Manual item 2.4.1.1.1,
PU PCB Replacement Function) of the Utilities in item (1), into the EEPROM of
the new PCB
Note!
In case when the EEPROM information is going to be obtained by using the
Maintenance Utilities, and when it is going to be written, set the MFP into
the [Forced ONLINE mode] by using the procedure described below, before
accessing the EEPROM. If MFP is in any error condition, the error display is
issued also in the Forced ONLINE mode.
1. When turning ON the power of MFP, execute item 5.12 Special Startup,
and run the MFP by the key code 105 [ON LINE mode always].
2. If status of MFP remains normal, the “ONLINE” display appears. If an error
occurs in the MFP, error display appears. However, inside of the MFP is in
the ONLINE status, communication is possible in this status.
2. In the case if access to the EEPROM of the PCB that is going to be removed is
impossible.
If the SERVICE CALL 104 (Engine EEPROM Error) is displayed on the Operator
Panel of the PCB that is going to be removed, or if the EEPROM data cannot
be read out, execute the following work by using the Maintenance Utilities after
replacement with new PCB is completed.
(1) Setting the PU serial number (Refer to the Maintenance Utilities Operation
Manual item 2.4.1.1.2, PU PCB setting.)
The SAP serial number has been applied to the MFP. The SAP serial
number is displayed in the top-most column of the serial number label, and
consists of two digits of manufacture location, two digits of manufacture
date, six digits of manufacturing number (sequential No) and two digits of
revision totaling 12 digit number.
• The PU serial number is the 10-digit number of the SAP serial number
excluding two digits of revision.
• Set the PU serial number by using the screen of item 2.4.1.1.2.2 [PU
serial number setting] of item 2.4.1.1.2 [PU PCB setup function] of the
Maintenance Utilities.
• When specifying the PU serial number, enter the 11 digit number to which “0”
(half size zero) at the top of 10-digit number. (When the PU serial number
is read, it is the 10-digit number.)
Input the 11-digit number that is made up by excluding the two-digit
revision, and by adding half-size before the 10-digit number.
• The PU serial number is output to the Printer Serial Number column of the
Menu Map header. Therefore, confirmation of the PU serial number after
the PU serial number is re-written should be made by printing out the Menu
Map.
Input the 11 digit number to which “0” (half size zero) at the top of 10-digit number.
(Input “0AE01234567”.)
