Firmware or service files for Canon printers, labelled for error E460 together with E464, in a RAR archive of roughly 21.6 MB. No printer model appears in the name, so check the contents for the supported models and any instructions. Canon shows such E-codes on the panel when a cartridge or ink system fault is detected, and technicians collect tools and firmware to address them. Verify compatibility with the specific machine before writing firmware, since a wrong image can leave the printer unusable.
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.
