hello
The model name is Canon IPF8300S.
After replacing a used main board due to a board defect, e196-404e occurs.
I can't even download the firmware, what should I do?

An EEPROM read/write error has been detected in the controller (firmware). seems your used board is not working. if you can't enter the download mode, the manual says: Replace mainboard.
