Notes on CU/PU board replacement
When the EEPROM on a board to remove can be accessed
(when SERVICE CALL 104 [Engine EEPROM Error] or 40 [EEPROM Error] is not displayed):

1. Remove information from the EEPROM in the PU block, and setting information from the EEPROM in the CU block, of the board, and temporarily store them onto an HDD of a computer, by using the board replacement function of
   Maintenance Utility.
2. By using the board replacement function, copy the information and setting information into the EEPROM of a board to replace with.
3. When only the information or setting information can be removed from the board to replace, copy it into the EEPROM of the replacement board by using the board replacement function. With the board replacement function, separately configure the other information, which cannot be removed. Perform PU-block serial-number setting (Maintenance Utility Operating Manual, section 2.4.1.1.1.5), and make a change to the Shipping mode (Maintenance Utility Operating Manual, section 2.4.1.1.1.6), in setting windows when the information cannot be removed. Configure CU-block serial number information (Maintenance Utility Operating Manual, section 2.4.1.1.1.4) when the setting information cannot be removed.

When removing or writing information from/into the EEPROM by using Maintenance Utility, use the procedure shown below to place the printer to the Forced ONLINE mode before accessing the EEPROM. Even in the forced
ONLINE mode, the printer provides an error indication when having an error.

1. When turning on the printer, press and hold down , and the OK button in combination until STATUS MODE appears on the operator panel.
2. The printer displays ONLINE when operating properly, and provides an error indication when having an error, where the printer is internally online, being ready to communicate.

Notes on CU/PU board replacement
When the EEPROM on a board to remove cannot be accessed:
When the operator panel displays SERVICE CALL 104 (Engine EEPROM Error) for, or data cannot be read from the EEPROM of, a board to remove, follow the following procedure to perform operation by using Maintenance Utility after the board is replaced with a new one:

1. Serial number setting (Maintenance Utility Operating Manual, section 2.4.1.1.7.3)
   A SAP serial number is assigned to the printer. The SAP serial number is at the top of the serial number label of the printer, consisting of a total of 12 characters -- two characters that indicates a production place, two characters that indicates a month and year, six characters that indicates a manufacture number (sequence number) and two characters that indicates a revision number.
   
   • Select PU Serial Number under “Select printer serial number”, and “Display the serial number only” under Display mode. Do not enter the CU serial number.
   • The PU serial number is 10 characters a two-character revision number excluded from the 12-character SAP serial number.
   • Make settings in the window for the serial number information setting described in section 2.4.1.1.7.3 in section 2.4.1.1.7 about board setting functionality.
   • To specify a PU serial number, in the PU serial number setting window, enter an 11-character number with the first character a single-byte zero (0) (note a read PU serial number is 10 characters), i.e. a 10-character number prefixed with a single-byte zero (0), such as the number shown in the following image, excluding the revision number two digits.
   • The printer outputs the PU serial number in the header of the printer's configuration report (a Menu Map). After the PU serial number is changed, it can be checked by printing a Menu Map from the printer.
2. Change to Shipping mode (section 2.4.1.1.7.4 of Maintenance Utility Operating Manual)
   The printer is placed in the Factory mode after the CU/PU board is replaced with a new one. Switch the printer to the Shipping mode.
   • Use the window for the Factory/Shipping mode described section 2.4.1.1.7.4 in Maintenance Utility section 2.4.1.1.7 about board setting functionality

Note:
Note that replacing the EEPROM (the engine control board) clears life information about units, including the belt, toner and image drums, causing errors in managing the lives of the units until the units are replaced. Below is the counts cleared with such CU/PU board replacement. When the units are replaced with new ones, their respective counts except for Total Sheets Fed are cleared, the errors being corrected.
