Manual Three-Key Download Sequence

If the flash memory contains only boot code (e.g., if it is new), or if flash memory is corrupt, or you want to
delete all Flash User Files, you must download software using the manual three-key download method.
There are two different methods available:
•
With the USB and firmware in the form FILENAME.exe or FILENAME.prg.
•
With the SD card and firmware FILENAME.prg renamed to "UPGRADE" in the SD card root directory.
1. Set the printer power switch to O (Off).
2. For the USB method, connect the USB cable to the printer interface.
3. For the SD card method, copy FILENAME.prg to "UPGRADE" (no extension) into the SD card root
directory and place into the SD card slot.
4. Press and hold down the LEFT SOFT KEY, RIGHT SOFT KEY, and DOWN ARROW panel keys.
5. Set the printer power switch to I (On).
6. After five seconds, release the control panel keys.
7. The printer must power-up so this may take up to 1-2 minutes. Wait until "DOWNLOAD MODE"
displays on the screen before proceeding.
8. For the SD card method, the downloading process will automatically begin. Wait until it completes and
the printer is fully rebooted with the new firmware. Then remove the SD card – this completes the
process.
9. For the USB method, start a Windows Command Prompt session.
10. Navigate to the directory with the target firmware (e.g., c:\download).
