Epson ET-15000 Inspection Mode Codes: Are There Any New Reset Codes or Secret Menu Updates?

Question: Is there any new code for the Epson ET-15000 inspection/maintenance mode?

I watched your video about Epson ET-15000 inspection mode and the "set jig / secret menu" process, and I'm hoping there's a new code available. Is there any updated or new code for the Epson ET-15000?

Answer: 

Why the answer is "no" (and why codes often stop working)

For the Epson ET-15000, there generally is not a "new code" that's publicly available in the way people hope. Epson changes how access works over time, and what many viewers call a "code" is often one of the following:

1. A keypad/sequence entry that only works on certain firmware revisions.

2. A maintenance/inspection mode access method that depends on hardware conditions (like a "set jig" behavior or a specific board state).

3. A service procedure, not a single code-meaning it requires software tools, a particular workflow, and sometimes hardware-level access.

As Epson updates firmware and board revisions, some older entry sequences become disabled or restricted, and there typically isn't a universal, user-facing replacement code that restores access across all units.

What "Inspection Mode" and "Set Jig" usually imply on ET-series printers

On many Epson EcoTank models, inspection mode (and anything described as set jig) is essentially a service environment intended for factory or service-center use. It may expose functions like:

• sensor checks and motor tests

• head/capping/pump movements

• EEPROM-related operations (model-dependent)

• internal counter reads/resets (model-dependent)

The key detail is that access is often tied to:

• firmware version

• mainboard/formatter configuration

• EEPROM data / region settings

• service tool communication (not something a keypad code alone can replace)

So if someone is asking for a "new code," what they usually need is actually a way to restore service access or correct the underlying logic lock-often board/EEPROM related.

The practical solution we can offer

Even though there isn't a new public code, your proposed answer is the most realistic path:

If you send us the mainboard, we can often reprogram it for you.

That matters because on many ET-series units, the restrictions and locks are not just "menu settings"-they can be stored in the board's memory (EEPROM/flash). Reprogramming the board can help when a printer is stuck due to internal configuration issues, region mismatches, certain service locks, or corrupted settings.

Important note: Reprogramming feasibility depends on the exact board revision and what specifically is locked or failing. But in general, if someone is hunting for a "new code," it's because the board's configuration is what needs to change-not because Epson quietly released a fresh unlock sequence.

Addressing printer issues can be complicated because the problems are hands-on and often require direct testing. Because of that, we're not able to provide remote troubleshooting, step-by-step repair coaching, or individualized printer repair support from a distance. We do offer an in-person evaluation and repair service through our local diagnostic facility (printer repair service [https://bchtechnologies.com/printer-repair-service]). Due to high demand, we work on a first-come, first-served basis, and it may take a few weeks before we're able to accept your printer for drop-off. Our services are structured to repair either an entire printer or specific parts, with clear instructions on how to proceed. We also understand our rates may not be the most budget-friendly, so we strongly recommend self-help through online research. A great place to start is YouTube, including our channel homepage (BCH Technologies on YouTube [https://youtube.com/@bchtechnologies]). To quickly find the most relevant videos, use the search icon near "About" on the right side of the menu bar. I receive dozens of questions every day asking for a specific video, and after creating content over the past nine years, it's tough to remember every topic we've covered-so YouTube search is the fastest way to get targeted results, and it may also recommend helpful videos from other creators.

Thanks again for reaching out and for supporting BCH Technologies. We genuinely appreciate you watching the videos and taking the time to comment, and I hope this clears up why there isn't a "new code" for the ET-15000-and what your best options are going forward.
