How to Fix Epson ET-15000 Error Code 031006: DIY Repair Tips from BCH Technologies

Customer Question:

I'm getting an error code 031006 on my Epson ET-15000 printer. I’d like to try fixing it myself—any advice on what to do?

Answer:

Understanding Error Code 031006

The Error 031006 typically indicates a fatal hardware error on Epson inkjet printers, including the ET-15000. From our experience and user-reported patterns, this error is often associated with the following root causes:

• A blown mainboard fuse (especially the fuse that controls the printhead).

• A short circuit in the printhead.

• A damaged or faulty FFC (Flat Flexible Cable) connecting the printhead to the mainboard.

This is a cascading type of failure: once one component fails, the others are likely to be compromised as well. If you only replace one element, there's a high chance the printer will return the same error immediately.

Recommended Fix

Here’s a more detailed guide for tackling this issue:

1. Inspect and Test the Mainboard Fuse

   • Remove the mainboard and use a multimeter or microscope to inspect the fuses.

   • If a fuse is blown, it’s likely due to a short in either the printhead or cable.

   • You can replace the fuse manually if you’re skilled with soldering and surface-mount components.

2. Replace the FFC Cable

   • Even a small nick or bend in the FFC can cause a short. Replacing it is cheap and relatively easy.

3. Replace the Printhead

   • If the printhead has an internal short, it will continue to blow fuses or trigger 031006.

   • Ensure the replacement printhead is compatible and ideally new (not pulled from a used machine).

4. Replace or Repair the Mainboard (if needed)

   • If the fuse replacement fails or the board has sustained more severe damage, replacing the board may be necessary.

   • BCH Technologies offers mainboard repair services, and we can help guide you through sourcing the correct board and printhead if needed.

Final Notes on DIY Repair

If you're comfortable with electronics—especially working with small components and navigating fragile printer internals—you can tackle this repair at home. Just be aware that replacing only one part (e.g., the printhead, but not the cable) often leads to recurring problems. It’s best to replace all three: the mainboard, the FFC cable, and the printhead, all at once.

In-Person Support

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. Therefore, we're unable to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility [https://bchtechnologies.com/printer-repair-service]. Given the high demand, we operate on a first-come, first-served basis. Therefore, it may take a few weeks before we can arrange for your printer to drop it off. Our services are structured to repair either the whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage [https://youtube.com/@bchtechnologies]. Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be the most efficient approach. Additionally, YouTube may suggest relevant videos from other channels that can assist you.
