The following describes the adjustments necessary after part replacement:
Replaced part
Adjustment
LED head
Not necessary.
Drum cartridge (yellow, magenta, cyan,
black,spot color)
Not necessary.
Fuser unit
Not necessary.
Belt unit
Not necessary.
PU/CU board
Copying information stored in EEPROM, which
requires utility software.
5.4.1 Notes on PU/CU board replacement
1. When the EEPROM on a board to be removed can be accessed
(When SERVICE CALL 104 (Engine EEPROM Error), or 40 (EEPROM Error) is not
displayed):
(1) Using the board replacement function of Maintenance Utility (Maintenance
Utility operation manual, section 2.4.1.1.9 about Board replacement
functionality), take out the information of the EEPROM on PU and Information
of the EEPROM settings on CU from the board to be removed, and temporarily
store it onto an HDD of the computer.
(2) Using the board replacement function of Maintenance Utility (Maintenance
Utility operation manual, section 2.4.1.1.9 about Board replacement
functionality), copy the information of the EEPROM on PU stored in HDD of the
computer and the information of EEPROM settings on CU onto the EEPROM
of a board to be newly installed.
(3) Even when either information of EEPROM on PU or information of the
EEPROM settings on CU is taken out, using the board replacement function
of Maintenance Utility (Maintenance Utility operation manual, section 2.4.1.1.9
about Board replacement functionality), copy either information of EEPROM on
PU or information of the EEPROM settings on CU which can be stored in the
HDD of the computer onto EEPROM of a board to be newly installed.
Information that cannot be taken out is separately set up in the same function.
When the information of EEPROM on PU cannot be taken out, make a setting
of the serial number on PU (Maintenance utility operation manual, section
2.4.1.1.9.5) and a setting of switching to the Shipping mode (Maintenance utility
operation manual, section 2.4.1.1.9.6) on the setup screen.
When the information of EEPROM settings on CU cannot be taken out, make
a setting of the information about a serial number on CU (Maintenance utility
operation manual, section 2.4.1.1.9.4) on the setup screen.
Note!
When taking out or writing information from/into EEPROM by using
Maintenance Utility, use the procedure shown below to place the printer to the
Forced ONLINE mode before accessing the EEPROM. An error message is
displayed even in the forced ONLINE mode when the printer has an error.
i. When turning on the printer, press and hold down the
BACK
button and
MENU
button and
OK
button in combination until display the "Status
Mode".
ii. When the printer operates properly, the operation panel shows “Ready to
Print”. However, when the printer has an error, it indicates an error, but the
printer is internally online, being ready to communicate.
2. When the EEPROM on a board to be removed cannot be accessed:
When SERVICE CALL 104 (Engine EEPROM Error), or 40 (EEPROM Error) is
displayed, or data cannot be read from the EEPROM, after replacing the board to a
new one, follow the following procedure to perform operation by using Maintenance
Utility:
(1) Serial number information setting (applicable Maintenance Utility operation
manual, section 2.4.1.1.10.3 about PU board setup)
A SAP serial number is assigned to the printer. The number is placed at the top
of the serial number label of the printer, consisting of total twelve characters --
two digits that indicate a production place, two digits that indicate a month and
year, six digit that indicate a manufacture number (sequence number) and two
digit that indicate a revision number.
• For the printer serial number, “PU serial number” should be selected, and for
the output mode, “Display the serial number only” should be selected.
CU serial number should not be entered.
