Disclaimer: Using third-party adjustment programs typically voids your Epson warranty. Proceed at your own risk.

Before running the program, ensure you have a backup of your printer’s EEPROM data. If the program crashes during the "69 reset," the mainboard may become bricked, requiring a desoldering of the memory chip.

For users of the wide-format Epson L1300, nothing halts a print job quite like the ominous glow of the error lights accompanied by the dreaded “Service Required” message, often paired with a hexadecimal code: 69 .
