The E9 error code is primarily indicative of a software or firmware issue, such as corruption during a boot-up sequence or a critical system error. While less common, persistent E9 errors after extensive troubleshooting could potentially point to an underlying hardware component failure, especially one related to the printer's main logic board or memory, preventing proper firmware loading.
