How to Undo a Firmware Update on Epson WF-7310 Used for Sublimation Printing

Question:

I accidentally updated the firmware on my Epson WF-7310, which I use for sublimation printing. Is there a way to undo the update and restore it to factory settings?

Answer:

Understanding Firmware Lockout on Epson WF-7310

When you accidentally update the firmware on an Epson printer like the WF-7310, it often leads to a frustrating problem, especially if you're using third-party ink systems like those for sublimation. Epson’s firmware updates are designed to block non-OEM cartridges, which can disable or reject your current ink setup.

Fortunately, there are several methods to attempt a firmware rollback or restoration. Here’s a breakdown of what you can try:

1. Try Epson’s Recovery Mode and Firmware Tool

Start by restarting your printer in Service Mode:

• To do this on most Epson models, hold down specific button combinations while powering on the printer. For the WF-7310, this often involves pressing the Stop, Left Arrow, Home, and Power buttons together.

• If successful, the printer will boot into a firmware recovery mode, which is ideal for flashing an older firmware version.

Next, download the older firmware version from a trusted forum or backup site and attempt to flash it using Epson’s official Firmware Updater tool.

2. Use WICReset Utility for Firmware Rollback

If the above method fails, the WICReset software can help:

• WICReset allows you to downgrade the firmware by forcing a reinstall of an earlier version (if available).

• You will need to purchase a firmware key and follow the instructions provided on their website or through the software tool.

• Make sure you disable internet access temporarily to prevent Epson from auto-updating again during the process.

This is often the most user-friendly method, as it does not require hardware-level intervention.

3. EEPROM Binary Dump Method

If both software-based approaches don’t work, a more advanced solution involves rewriting the printer’s memory:

• Search for a binary dump file (search for: bin dump WF-7310 site:bchtechnologies.com Or other trusted Epson modding communities.

• You’ll need to either build an EEPROM programmer or buy one from Amazon.

• Carefully write the firmware binary dump into the printer’s EEPROM chip. This essentially bypasses the corrupted or restricted firmware with a known working version.

If the firmware corruption is severe or if the EEPROM chip has been damaged, you might also want to replace the EEPROM chip entirely with a fresh one preloaded with a working firmware.

⚠️ This is an advanced method and should only be attempted if you're comfortable with soldering and low-level hardware programming.
