5.7 FIRMWARE UPDATE
The features in this section, “Firmware Update,” are valid when the optional CF
expander is not installed.
5.7.1 TYPE OF FIRMWARE
There are four types of firmware as shown below.
Type of firmware
Function
Number of IC cards
required
1. Main
Printer engine control
1 card
2. MUSIC
Line position adjustment
1 card
Printer Engine
3. DSP
Line position adjustment
1 card
4. System
Printer system firmware
2 cards
Printer Controller
5. NIB
NIB firmware
1 card
Refer to "5.4.3 Controller/Engine Firmware Upgrade" for the procedure.
NOTE:
When upgrading all five types of firmware at the same time, you can
upgrade them in any order.
However, when upgrading the controller system firmware, use the cards in
the correct order (see below).
Two IC cards are needed to upgrade the controller system firmware. One
IC card is for the operating system, and the other is for the printer
application. Always upgrade the operating system first, then the printer
application.
5.7.2 ERROR RECOVERY
Engine Firmware/Controller NIB Firmware
If a download attempt has failed, try downloading the new firmware again using the
procedure described in section 5.4.3.
NOTE:
When a download fails, the error is logged in the NVRAM on the controller
and the machine asks you to insert the appropriate IC card.
Even after replacing the BCU board to fix the problem, the same message
will continue to be displayed. Turning off and on the main switch while
holding down the Menu and Enter keys clears the error condition logged in
the NVRAM on the controller.
Controller System Firmware
If a download attempt has failed, you must boot up the machine from the IC card.
To do this, DIP SW 1 on the controller board needs to be ON. The machine
automatically starts upgrading the firmware.
