For a true, forensic-level , nothing beats a dedicated EEPROM programmer. This method is non-invasive to the firmware and works even if the mainboard is completely dead. This is a common repair procedure for Epson
If the old main board is too damaged to power on for a software read, you can move the physical memory chip. EEPROM data copy For a true, forensic-level ,

: This is widely considered the best for non-technical users to create an "EEPROM dump" or backup. How to Use : Connect the printer via USB, navigate to the Information section, and select under the EEPROM settings. Availability
