Canon E400 printer firmware dump with the name stating 2MB, matching a 16 Mbit serial flash chip, packed in a RAR of about 1 MB. It serves to reprogram a corrupted main board memory and bring back a printer that no longer starts normally. Check the chip on your PCB is indeed 2MB, since an image of the wrong size will not fit. Save the original contents before writing so you keep a fallback if the result differs.
