Firmware dump taken from a Canon IX6840 printer, read from an N25Q064A13 serial flash chip and stored in a RAR archive of about 6.11 MB. The N25Q064 is a 64 Mbit (8 MB) SPI NOR device, so the extracted image should match that capacity. A dump like this is used to restore a printer whose flash content has corrupted, causing boot failure or error loops, by writing it with an external programmer such as a CH341A. Read and keep the original chip contents first, as device-specific settings and counters may be stored in the flash.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
