An EEPROM dump is a binary file containing the raw data stored in the Epson printer's memory chip. This data includes: Serial numbers. Ink level counters. Waste ink pad counters (maintenance box). Printer model information.
The original .bin file is extracted via software or a physical programmer (such as a CH341A programmer clipped to the IC chip).

An EEPROM dump is a byte-by-byte binary copy of the non-volatile memory stored on the printer's main logic board. Unlike volatile RAM, which clears when power is lost, the EEPROM retains crucial configuration data, including:
You cannot do this with just a USB cable and Epson’s software. You need hardware programmers: An EEPROM dump is a binary file containing
Tools like the CH341A Pro , RT809F, or TL866II Plus are standard industry choices for reading and writing SPI/I2C chips.
Technicians use hardware programmers (CH341A, TL866, or RT809H) connected via SOIC-8 clips or direct soldering to the EEPROM chip (commonly a Winbond or Macronix IC on Epson boards). The software reads the chip’s contents and saves them as a dump. Waste ink pad counters (maintenance box)
Here is a called epson_eeprom_patcher.py . It is designed to work with dumped EEPROM bins (usually 24C04, 24C08, 24C16, 24C32, or 24C64 from Epson mainboards).
