Firmware package for the Epson L310 ink tank printer, labelled as a master copy and packed in a 419 KB RAR archive. The name gives no firmware version, so the exact contents are only known after extraction. Printer master dumps like this are normally written to the main board's serial flash with an SPI programmer when a printer is bricked, stuck in an error loop or left dead after a failed update. Read and save the original chip contents first, and confirm the flash capacity matches the image size before writing anything.
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.
