3. During Step 2 (i.e. when the status indicator blinks in orange with the depression of the power button), turn
on the destination printer by pressing and holding the [FEED] button. After the destination status indicator
blinks in red twice, release the two buttons which are being held.
NOTE:
In case the destination status indicator doesn't blink in red twice, the printer doesn't enter the
download mode. Retry to turn on the destination printer by pressing and holding the [FEED]
button.
4. When ensuring the destination printer was on, the source one starts transferring the firmware data via IrDA
communication.
5. During data transmission, the source status indicator blinks in green and in orange alternately. The desti-
nation one blinks in green.
NOTE:
After having received the data, the destination status indicator lights in green, indicating that the
Flash ROM erase and write is performed. Never turn off the printer nor remove the battery while
the printer is working.
6. Data transmission is completed in approximately 3 minutes.
7. After the data transmission is completed successfully, the source status indicator keeps blinking in green.
After the Flash ROM erase and write was completed successfully, the destination printer restarts automati-
cally while the status indicator blinks in red, blinks in green, then lights in green.
8. If an error occurs during data transmission, either of the status indicator blinks in red. Retry from Step 1.
NOTE:
Do not move the printers nor interrupt their IrDA interface windows during data transmission. Doing
so may fail in IrDA communication.
4.3.7 Execution of Download by using the IrCOMM Protocol
1. Match the printer communication conditions for the PC and the printer. Turn on the printer while holding
down the [FEED] key to turn the printer to the system mode. Face the IrDA interface windows of both PC
(or a device) and the printer. (Direction of the printer's IrDA depends on the setting.)
2. Click on the [Start(S)] of the [Transmission(R)] on the screen to start downloading.
When the printer enters the download mode, the status indicator slowly blinks in red twice.
When the printer is in the download mode, open a file for downloading.
NOTES: 1. Be sure to open a file for downloading first.
2. If the status indicator doesn't blink in red twice, the printer doesn't enter the download mode.
Turn off then on the printer, make sure the communication conditions, and then retry from
Step 1.
3. During transmission, the progress indicator is not displayed at the bottom of the screen.
NOTES: 1. For IrDA communication, do not interrupt the IrDA interface windows of both PC and the
printer nor move the PC and the printer during data transmission.
2. Never turn off the printer nor remove the battery from the printer during data transmission.
Doing so may cause an error.
3. If an error occurs during data transmision, retry from Step 1.
4. Whether the downloading is completed properly or not is indicated by the status indicator as
follows:
When succeeded:
When error occurs: Blinks in red
4. After completing the download, be sure to turn off the printer by pressing the power button.
Blinks in green (downloading) → Lights in green (Writing data) → Blinks
in green and red alternately. (Normal completion)
