Firmware for the Canon i-SENSYS MF3010 multifunction laser printer, packed in a 3.29 MB RAR archive. No firmware version or chip type is mentioned in the name. Repairers use such dumps to recover a unit that no longer starts properly or shows controller errors, by reprogramming the main board memory. Check the archive for notes on the target chip. Read and keep the original contents before writing, and compare the image size with the chip capacity before you program it.
