Firmware dump for the Canon PIXMA MX537 multifunction printer with fax, stored in a RAR archive of about 9.3 MB. The name gives only the model, so the archive likely holds the main board flash and possibly EEPROM data. Such images restore boards that will not boot, sit in a support code loop or were damaged by an interrupted update. Identify the chip on the board, make sure its size suits the image, and save the original contents before reprogramming.
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.
