Ensure the printer is set to the correct interface (typically USB for firmware loading).
If you have the firmware file already, I can help you interpret the release notes, check version strings, or explain update procedures (safe mode, boot block, recovery). Just let me know what exact version you’re looking at or what symptom you’re trying to fix.
