Memory dumps for the Canon G3400 printer, with the name pointing to 25Q16 and 25Q64 SPI flash chips, meaning 16 Mbit and 64 Mbit parts. The 7.91 MB RAR archive likely holds one image per chip, so check which file corresponds to which device on the logic board. Technicians write these with an SPI programmer to recover a board with corrupted firmware. Always back up the current chip contents before writing, and confirm the image size matches the chip, since a 2 MB file belongs on the 25Q16 and an 8 MB one on the 25Q64.
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.
