Epson printers use Electrically Erasable Programmable Read-Only Memory (EEPROM) to store persistent configuration data, including serial numbers, model identifiers, and lifetime page counters. A "patched" EEPROM dump refers to a firmware image that has been modified to reset these counters or change the printer's identity to bypass manufacturer-imposed limitations, such as the "end of service life" error caused by full waste ink pads. eeprom dump epson patched
