Firmware archive for the Epson L6490 printer, containing dumps of the chips referenced as IC201, IC202 and IC601 on the main board. These are memory chips read from the logic board, used to restore a printer after firmware corruption or a failed update. Write each dump to the matching IC position with a suitable programmer. Save the original chip contents first, since they may hold counters and unit-specific settings, and confirm chip types and capacities before flashing.
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.
