Epson Error Code 031006 After Fuse Repair: What It Means and What to Check Next

Question:

My Epson printer just came back from a repair shop where they reconnected a fuse. It still wasn't printing ink, so I cleaned the printhead, and now it shows error code 031006. What should I do?

Answer: 

What error 031006 usually indicates

On many Epson models, codes in the 031xxx family commonly point to an electrical/communication fault involving the printhead circuit-not a "clog" issue. In other words, the printer is detecting an abnormal condition related to the printhead's driving signals (or what's connected to it), and it shuts down to prevent damage.

That's why this often appears after a fuse-related repair: the fuse may have been reconnected (symptom treated), but the original cause of the fuse event may still be present (root problem untreated). When the printer tries to initialize the head again, it detects the fault and throws 031006.

Why "it wasn't printing ink" matters here

When a printer suddenly stops printing ink entirely, people naturally suspect a clog. But when it comes right after electrical work (or a blown/disconnected fuse), "no ink" can also happen because the printer isn't driving the head correctly-meaning the head may not be firing at all due to an electrical failure, driver failure, or a cable issue.

Cleaning the head (or doing heavy cleanings) doesn't typically cause 031006 by itself, but it can coincide with the printer attempting repeated head energizing during cleaning cycles-bringing an existing electrical problem to the surface.

The likely root causes (in order of how often we see them)

Based on your timeline-fuse repair → still no ink → cleaning → now 031006-the shop likely restored power/continuity but didn't fully diagnose why the fuse issue happened in the first place. Most commonly, it comes down to one of these:

1) Printhead failure (internal short or electrical fault)

A failing printhead can short internally or draw abnormal current. That can trigger fuse issues and later throw an initialization error like 031006. If the head is electrically damaged, cleaning won't fix it-because the issue is not "blocked nozzles," it's "electronics."

What this looks like:

• Printer powers on but errors out during initialization/cleaning

• Sudden complete loss of ink output (not gradual fading)

• Error code 031006 repeats consistently

2) FFC cable problem (printhead ribbon cable)

The printhead connects through one or more FFC cables (flat flexible ribbon cables). If the cable is:

• not seated perfectly,

• inserted backwards/misaligned,

• torn/creased,

• oxidized/contaminated at the contacts,

...the printer may detect bad communication or abnormal head readings and throw 031006.

Important: After a shop repair, a slightly mis-seated FFC is extremely common-especially if the repair involved board access, fuse work, or head-area reassembly.

3) Mainboard/head driver circuit failure ("printer driver chip")

This matches what you suspected: the head driver circuitry (often on the mainboard) can fail. Sometimes the driver chip fails first and blows/disconnects a fuse. Other times, a failing head causes the driver to fail. Either way, the printer ends up throwing a head-related electrical code like 031006 because the head cannot be driven or read normally.

Clue: If you replace/verify the head and cables and the code persists, the board/driver becomes much more likely.

What to do next (practical checklist)

Because 031006 is typically an electrical/connection fault, the best approach is to work from the simplest/least expensive checks to the most expensive parts.

Step 1: Stop running cleanings for now

Repeated cleanings can stress the head electronics and the power circuitry. With 031006 present, more clean cycles usually won't help and can make a marginal electrical problem worse.

Step 2: Inspect and reseat the printhead FFC cable(s)

This is the first thing we'd verify in-person because it's common and sometimes "instantly fixes" the issue.

• Power off and unplug the printer.

• Locate the FFC cable(s) running to the printhead carriage.

• Check for kinks, tears, burn marks, or crushed sections.

• Carefully reseat the cable straight and fully into its connector (even slight misalignment can trigger errors).

• Make sure the locking tabs/clips are properly engaged.

If the cable is damaged, it needs replacement. A damaged FFC can also lead to intermittent shorts and fuse events.

Step 3: Evaluate whether the printhead is electrically compromised

If the cable checks out and 031006 persists, the printhead itself becomes a prime suspect-especially given the earlier "no ink" symptom after the fuse repair.

Printhead electrical testing and confirmation usually require hands-on diagnostics (and model-specific procedures). In many Epson cases, once the printer throws a consistent 031006, it means the printer is protecting itself from driving a head circuit it believes is unsafe.

Step 4: Consider the mainboard/head driver ("printer driver chip") as the next suspect

If a known-good head and known-good cable still trigger 031006, then the failure is likely on the mainboard/head driver circuit.

This is also why a shop "reconnecting a fuse" is often not enough: the fuse was a protective response, not the cause. The underlying cause may be:

• a shorted printhead,

• a compromised FFC,

• or a failing driver circuit.

A quick reality check on "what caused it to start with"

Your situation strongly suggests the shop fixed the symptom (fuse continuity) but didn't fully trace the root cause. That's exactly what you suspected-and you're thinking in the right direction:

• It could be the printhead,

• it could be the FFC cable,

• or it could be the printer driver chip/mainboard.

And unfortunately, those three are tightly linked: one can damage the others, so the key is careful step-by-step testing rather than swapping parts blindly.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility, printer repair service (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis. So, it might take a few weeks before we can get your printer to drop it off. Our services are structured to repair either a 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 highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage, BCH Technologies on YouTube (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 most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.
