5.4.1 Notes on CU/PU board replacement

1. 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 (Maintenance Utility Operating Manual, section 2.4.1.1.9
about board replacement functionality).
(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 2.4.1.1.9.5), and make a change to the Shipping mode (Maintenance
Utility Operating Manual, section 2.4.1.1.9.6), in setting windows when the
information cannot be removed. Configure CU-block serial number information
(Maintenance Utility Operating Manual, section 2.4.1.1.9.4) when the setting
information cannot be removed.

Note: 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
in combination until STATUS MODE appears on the operator panel.
2. The printer displays ONLINE when operating properly, and provides an
