[Arc] Pcb-Assy-Arc1 Mnt/Pcb-Assy-Arc2 Mnt, [Eeprom] T2Arc-Eeprom Mnt - Oki LP-1040 Maintenance Manual

9.8.3 [ARC] PCB-ASSY-ARC1 MNT/PCB-ASSY-ARC2 MNT,
[EEPROM] T2ARC-EEPROM MNT
Note
PCB-ASSY-ARC1 MNT and PCB-ASSY-ARC2 MNT are available as recommended parts for the
ARC board. Pay attention when replacing the board as the PCB-ASSY-ARC1 can be replaced
only with the PCB-ASSY-ARC1 MNT, and the PCB-ASSY-ARC2 can be replaced only with the
PCB-ASSY-ARC2 MNT.
Since the replacement procedure is the same for both models, only the term PCB-ASSY-ARC is
used in the procedure below.
Note (Things to Consider When Replacing the Circuit Board)
After replacing the PCB-ASSY-ARC board with a new one, be sure to replace the new
PCB-ASSY-ARC's EEPROM with the original PCB-ASSY-ARC's one.
Replacing the board without replacing the EEPROM leads to the following problems.
- The message The printer will operate for 720 hour(s) only is displayed in yellow on the
Ready screen on the operatioin panel.
You will not be able to use the Printer after using it for the displayed time.
- Firmware options cannot be used.
* If the EEPROM is damaged or lost during replacement, purchase a new one with the EEPROM
serial number written on the order. (Product name: T2ARC-EEPROM MNT) (See 9.2.6
ELECTRICAL UNIT)
EEPROM
After replacing the PCB-ASSY-ARC board, remove the metal plate on the USB port of the original
board and install it on the USB port of the newly installed ARC board.
The USB port should be covered with the metal plate when the IC card reader is not used.
After replacing the board, always upgrade the firmware (see p. 1-9).
Reconfigure also the following items.
 Current time (Menu (1/2) -> Menu (2/2) -> Date and Time Settings)
 Product key (see p. 2-49)
See also 1.7 and 1.8 when replacing the ARC board.
