Flash memory image for the Canon E400 inkjet printer, the name carrying only the model, delivered as a RAR archive of roughly 1 MB. It can be compared with the separate 2MB-labelled E400 dump to pick the version that suits your board.

Verify the chip capacity, and use a programmer to back up existing contents before you erase and write anything.
