7.2.1 Special Modes for Servicing
0013-9804
This printer supports the following special modes in addition to the service mode:
- PCB replacement mode
- Download mode
- Counter display mode
1. PCB replacement mode
This mode is used when replacing the main PCB or MC relay PCB.
By executing this mode,
- Backup data of the settings and counter values stored in the MC relay PCB are moved to the new main PCB.
- The data such as the settings and counter values are copied to the MC relay PCB.
a) Entering the PCB replacement mode
Follow the same procedure as that for entering the service mode.
(With the [Paper Source] button and [Information] button pressed down, turn on the [Power] button.)
When the printer starts up, compare the serial number memorized in the main PCB's EEPROM with that memorized in the MC relay PCB's EEPROM. If they do
not match, or no serial number is memorized in either EEPROM, enter the PCB replacement mode.
While you are in the PCB replacement mode, the MESSAGE LED, roll media LED, and ONLINE LED are lit.
b) Procedure
Select "CPU BOARD" or "MC BOARD" using the [ ] and [ ] buttons, and then press the [OK] button to determine it.
- CPU BOARD
Select this after replacing the main PCB.
The data in the MC relay PCB is copied to the main PCB.
- MC BOARD
Select this before replacing the MC relay PCB.
The data in the main controller PCB is copied to the MC relay PCB.
c) Exiting the PCB replacement mode
Turning off the [Power] button of the printer allows you to exit the PCB replacement mode.
For details on how to replace the PCB, see DISASSEMBLY/REASSEMBLY > Points to Note on Disassembly and Reassembly > PCBs.
2. Download mode
