What does 'Server Error 03 Failed to upload' mean on my Brother All in One Printer?

If your Brother All in One Printer displays 'Server Error 03 Failed to upload. Unsupported file or corrupt data', it indicates a problem with the file you're trying to upload. This could be due to several reasons: * The file exceeds the service’s limit on number of pixels or file size. * The file type is not supported. * The file is corrupted. To resolve this, check the service's size or format restrictions, save the file as a different type, or try to obtain a new, uncorrupted version of the file.
