How to Fix Error Code 031006 on Epson WF7725

Question: I've encountered a persistent error code 031006 on my Epson WF7725. I recently installed a replacement printhead from AliExpress and may not have turned off the printer during the installation, which could have caused this issue or the printhead itself might be faulty. Could you help me address this error?

The error code 031006 on your Epson WF7725 indicates a "Head fuse broken error," which typically points to issues related to a printhead failure or a mainboard failure. This error often arises due to a faulty or incorrectly installed printhead that could potentially damage the mainboard by burning the head fuse. Given that you installed the printhead without turning off the printer, this might have contributed to the problem.

Here’s a step-by-step guide on how to troubleshoot and potentially resolve the 031006 error on your Epson WF7725:

Step 1: Power Down and Unplug First, ensure that the printer is turned off and unplugged from any power source. This is crucial to prevent any further electrical damage during the troubleshooting process.

Step 2: Access the Printer’s Internal Components Carefully open the printer casing according to the model’s service manual or guidance videos. This will allow you to access the mainboard and the printhead.

Step 3: Inspect and Disconnect the Printhead Inspect the printhead and the flexible flat cable (FFC) connections. Look for any visible signs of burns or damage on the FFC, as these are often indicative of the issues leading to the 031006 error. If the printhead appears damaged or if you suspect it’s faulty, consider replacing it.

Step 4: Examine the Mainboard Check the mainboard for any signs of electrical damage, such as burnt components or fuse issues. If the damage is extensive, the mainboard might need to be replaced. Take a multimeter and test the F1 and F2 fuses. This fuse can replace both fuses: https://bchtechnologies.com/f1-fuse-also-f2-f3-for-epson-mainboard-fix-error-0x9a-or-031006-on-wf-7720-wf-7710-wf-3640-wf-3620-wf-8510-et-8550-xp-15000/

Step 5: Replace Faulty Components If necessary, replace the damaged printhead or mainboard with genuine or high-quality third-party parts. Ensure that all connections are secure and correctly positioned before proceeding.

Step 6: Reassemble and Test Once all components are checked and any necessary replacements are made, reassemble your printer and reconnect it to the power source. Test the printer to see if the error persists.
