FIRMWARE UPDATE
4.5.2 FIRMWARE UPLOAD (CONTROLLER ONLY)
This creates a backup copy of the controller firmware on an IC card.
Note: The target IC card must already contain a version of the controller firmware.
1. Prepare an IC card with a version of controller firmware programmed.
2. Turn off the machine and install the card in the IC card slot on the controller.
Note: When you see the machine from the back, the "A" side of the card must
face the right side.
3. Turn on the machine and switch the display to "Printer" (use the "Printer" key
on the operation panel).
4. Check the firmware version as follows:
• CARD: Firmware version on the card
• ROM: Current controller or NIB firmware version
5. Press [Backup] to upload the firmware to the card.
Note: Do not press [Install]. [Install] will copy the firmware from the card to the
controller.
6. After the firmware upload has finished, turn off the machine, and remove the
card.
7. Turn on the machine.
