Archive tied to the Canon G2415 inkjet printer, a ZIP of about 1.40 MB. The name gives only the model, so its exact contents are unknown. It could hold firmware, a service tool or a repair document. Open it and check what is inside before using it on a machine. If it contains firmware, confirm the target model and region match the printer being serviced. Dumping the existing flash before any write leaves a way back if the update fails. Keep a copy of the unopened archive for reference.
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 @biositechyangiyer. Enginerys does not host this file.
