Resolving Error Code 031006 After Printhead Cleaning on Epson ET-3750

Q: After cleaning the printhead of my Epson ET-3750, I encountered a printer and scanner error with code 031006. Despite being cautious, I fear the printhead circuit board may have shorted. How should I proceed?

A: We sincerely appreciate you reaching out to us for assistance. At BCH Technologies, your engagement and trust in our resources, especially our YouTube channel, are invaluable. We're committed to helping you navigate through this concern with your Epson ET-3750.

The error code 031006 you've encountered typically indicates a "Blowout of a fuse error (Head)," signifying a failure in the power source to the printhead or an issue within the circuit itself. This can encompass a range of problems, from disconnections or damage to the head FFC (Flat Flex Cable), a blown fuse on the main board, to failure of the printhead itself. These issues could manifest during printer startup, amidst print operations, or following a flushing process.

Given the symptoms you've described, it's possible that the cleaning process may have inadvertently affected the printhead's circuitry or related components. To diagnose and address this issue effectively, here are a few steps:

1. Examine the FFC Printhead Cable: Inspect the cable for any signs of wear, tear, or burn marks. A damaged cable can result in the error you're experiencing.
2. Check the Mainboard's Fuse: The fuse related to the printhead's power supply may have blown. This requires a careful inspection and potentially replacing the fuse.
3. Inspect Capacitors: Nearby capacitors should also be checked for any signs of damage, as they can be impacted by issues with the fuse.
