5.4 FIRMWARE UPDATE PROCEDURE
5.4.1 TYPE OF FIRMWARE
There are two types of firmware, requiring four cards, as shown below.
Type of firmware Function
Number of PCMCIA
Memory cards
required
Printer Engine 1. Main Printer engine control 1 card
Printer Controller 2. System Printer system firmware 3 cards
Refer to “5.4.3 Controller/Engine Firmware Upgrade” for the procedure.
NOTE: When upgrading both types of firmware at the same time, you can upgrade
them in any order.
However, when upgrading the controller system firmware, use the PCMCIA
cards in the correct order (see the procedure as detailed on “5.4.3
Controller/Engine Firmware Upgrade” on the following page).
Its is recommended to first print-out the printer’s “Configuration Page” prior to
updating the firmware. Then, when the firmware has been successfully updated,
print a second “Configuration Page” and confirm the results.
5.4.2 ERROR RECOVERY
Engine Firmware
If a download attempt failed, try downloading the new firmware again using the
procedure in section “5.4.3 Controller/Engine Update.”
NOTE: When a download fails, the error is logged in the NVRAM on the controller
and the machine asks you to insert the appropriate PCMCIA memory card.
Even after replacing the ECB 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 failed, you must boot up the machine from the PCMCIA
memory card. To do this, DIP SW 1 on the controller board needs to be ON. The
machine automatically starts upgrading the firmware.
