Some chips use 3.3V, others 5V. Ensure your CH341A is configured correctly.
: Attributes such as the current firmware version, region codes, and error logs (e.g., paper jams or fatal errors) are mapped to specific EEPROM addresses. Technical Execution for Advanced Users eeprom dump epson

Applications like HxD to view, verify, and modify the .bin or .eep dump files. Technical Execution for Advanced Users Let me know,
A failed firmware update, sudden power outage, or interrupted data transmission can corrupt the EEPROM. When this happens, the printer may refuse to power on, display a blank LCD screen, or get stuck in an infinite boot loop. Writing a verified, clean EEPROM dump directly to the chip forces the hardware back into a functional factory state. 2. Motherboard Replacement and Serialization
The CH341A USB Programmer is the most popular, reliable, and budget-friendly tool for this task. For advanced multi-voltage chips, programmers like the RT809F or TL866II Plus are preferred.
