Dump set for the Canon MX397 multifunction printer covering two chips named in the file: a 24C64WP serial EEPROM and a W25Q128FV SPI flash of 128 Mbit. The EEPROM usually stores settings and counters, while the flash holds the main firmware, so each image must go back to its own chip. A programmer such as a CH341A with suitable adapter can read and write both types. Save the originals before overwriting, and check that each file size equals the capacity of the chip it is intended for.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
