How to Fix Epson WF-3720 Recovery Mode After Failed InkChip Firmware Update

Question:

I tried to install InkChip firmware, but my Epson Workforce 3720 is stuck in Recovery Mode. Your YouTube channel [https://youtube.com/@bchtechnologies] has nothing to say about this issue. I’ve previously used InkChip firmware on an Epson and had no problems with it. Do you have any tips on how to solve this?

Answer:

Reasons for Epson Printer Going Into Recovery mode

Your Epson WF-3720 went into Recovery Mode because the firmware installation was interrupted. This usually occurs if the printer was powered off or detached from the computer before completing the upgrade. An interrupted firmware installation leaves the printer's system recognizing a faulty or incomplete firmware and stopping regular printing functions.

How to Fix Epson WF-3720 Recovered Mode

Reload the inkchip Firmware.

Whatever the reason, since you tried to install the InkChip firmware, the first step is to try reaching into the installation again:

Ensure the printer is still connected via USB to the same computer on which you ran the InkChip firmware update.

The InkChip firmware tool can then be opened, and this firmware can be reinstalled to see if the printer will accept it.

Follow all on-screen instructions, and don’t turn off the printer until you have finished the process.

If the printer is not allowing a reinstallation, proceed to the next step.

WICReset —Firmware Version

For WICReset software, it can assist in repairing firmware problems by allowing you to install another firmware version in some situations:

• From the WICReset’s site [https://www.wic.support/], download the WICReset Utility.
• Launch the program and see if the software detects your printer in Recovery Mode.
• Flash an older or different firmware revision to see if the printer will accept it.
• Once completed, follow the instructions and reboot the printer.

Check if Epson has official recovery firmware and if WICReset fails.

Search for Recovery Firmware from Epson’s Official Website

Occasionally, Epson publishes an emergency recovery firmware that can get a printer trapped in Recovery Mode working again:

• Go to the official support page for Epson [https://www.epson.com/Support/].
• Search “Epson WF-3720” and find any firmware recovery tool.
• If Epson releases recovery firmware, install it according to the steps required.

Last resort: flash firmware manually with EEPROM writer

If all else fails, the mainboard firmware may be irreversibly corrupted. In this instance, your only recourse for recovering your printer will be to:

• Take out the mainboard from the printer.
• Check using an EEPROM programmer by directly burning a suitable firmware bin file on the board.
• Reassemble the mainboard and troubleshoot the printer.

This is a very technical method that requires tools. If you’re not comfortable with this process, consider getting a repair.
