Epson ET-2650 Stuck in "Printer mode" and Frozen Buttons: Fixing "Flag check / Inspection On / Initial charge: Off" Screen

Question: My Epson ET-2650 shows "Printer mode" and won't respond to any buttons. The only thing that works is pressing Power, and then the screen turns red with this message: "Flag check, Inspection On, Initial charge: Off, Push (Power) BT." How can I fix this?

Answer: 

What those messages usually mean

On the Epson ET-2650, seeing "Printer mode" with frozen buttons, followed by a red service-style screen that says:

• "Flag check"

• "Inspection On"

• "Initial charge: Off"

• "Push (Power) BT"

...strongly suggests the printer is booting into a service/inspection state but cannot complete normal startup. In plain terms, the printer's logic board is starting, but the firmware configuration it relies on is either corrupted, inconsistent, or stuck in a diagnostic flag loop.

This behavior commonly happens after:

1. A firmware update that didn't complete properly (power loss, interruption, USB disconnect, Wi-Fi drop, etc.)

2. Firmware/region data corruption stored in EEPROM/NVRAM

3. A failed downgrade attempt after an update (many people attempt this when updates affect third-party supplies)

4. Less commonly: logic board communication faults that prevent reading the needed startup data

Why EEPROM corruption is a common root cause

Your proposed explanation is right on target: EEPROM corruption can occur when memory cells inside the EEPROM/NVRAM begin to wear out. This is especially likely during a firmware update because the printer may write large blocks of data quickly. If any memory cells are weak, the write can fail and leave the printer with partially unreadable configuration/firmware pointers.

When the printer can't reliably read these settings during boot, it may:

• Freeze on a mode screen (like "Printer mode")

• Show diagnostic flags (like "Flag check" / "Inspection On")

• Stop responding to buttons because the main loop never reaches the normal UI state

Also, as you mentioned, Epson sometimes releases updates aimed at controlling supply compatibility. While the goal may be to restrict non-OEM supplies, updates can sometimes cause unintended side effects-even with genuine Epson consumables-leading users to attempt rollbacks. If the EEPROM has weak regions, the rollback can fail and the printer may become stuck in a state like the one you're seeing.

Step 1: Try software recovery first (only if the printer still communicates)

The easiest and safest fix is software-based-but it only works if the printer can still communicate with your computer through USB (and shows up as a device consistently).

A) Restart and attempt a recovery/firmware rewrite

If you can get the ET-2650 recognized by your computer:

• Restart the printer

• Connect by direct USB (avoid hubs)

• Try Epson's recovery or firmware reflash process (often packaged with Epson update tools or recovery utilities)

The goal is to overwrite corrupted firmware sections and restore a bootable state.

B) Try a firmware rollback tool (when appropriate)

If reflash doesn't work, tools such as WICReset may help roll firmware back to an earlier version. The reason rollback sometimes works is exactly what you stated: if corruption is limited to a certain region, a different firmware package or rollback routine may avoid the damaged area and allow the printer to boot again.

Important notes:

• Rollback is not guaranteed.

• If the EEPROM is physically failing, any software solution may be temporary.

• If the printer disconnects mid-process, it can get worse.

Step 2: If the printer does NOT communicate at all, hardware repair is usually required

If your computer cannot detect the printer reliably, or the printer never reaches a normal operational state, software tools won't have a path in. At that point, a hardware-level approach is the usual next step.

A) EEPROM programmer method (read/write a clean dump)

This involves accessing the EEPROM chip on the logic board and using an EEPROM programmer to:

1. Read the EEPROM contents (to confirm corruption or save what's there)

2. Write a known-good binary dump from a healthy Epson ET-2650 (or the correct matching board/firmware family)

You mentioned a ready-made programmer option here:
EEPROM programmer example (https://amzn.to/43HA5nw)

This approach bypasses the printer's normal boot process and writes the data directly.

B) Consider replacing the EEPROM chip

If corruption is happening because the EEPROM is wearing out, rewriting may not hold. In many cases, the best long-term repair is:

• Replace the EEPROM chip with a new one

• Then program it with a clean, correct data set

That gives the printer a stable memory component again, instead of relying on a failing one.

C) Why this is delicate

EEPROM work can be high-risk because it may require:

• Board disassembly

• Chip identification (exact part number matters)

• Clip-on programming vs soldering (depends on the chip/package and board layout)

• Ensuring the dump matches the correct model/board revision

A wrong dump or wrong write can "brick" the board further, so technicians usually verify the EEPROM type and confirm the dump source carefully.

Addressing printer issues can be complicated due to the hands-on nature of the problems, especially when the printer is locked in a diagnostic state like "Printer mode" and shows "Flag check, Inspection On, Initial charge: Off, Push (Power) BT." Because we can't physically inspect the unit or verify communication and board condition remotely, we're not able to provide remote troubleshooting, step-by-step repair guidance, or direct support for printer repairs. 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 operate first-come, first-served, so it may take a few weeks before we can schedule your drop-off. Our services are structured to repair either the entire printer or specific parts, with clear instructions on how to proceed. However, we understand our rates aren't the most economical, so we strongly recommend self-help through online research first. You can begin by checking YouTube, including our channel homepage: BCH Technologies on YouTube (https://youtube.com/@bchtechnologies). Use the search icon next to "About" on the right side of the menu bar to locate videos on your exact issue. I receive dozens of requests daily asking if we have a video for a specific topic, and after nine years of creating content it's difficult to remember every single one-so YouTube's search is the fastest method. YouTube may also suggest relevant videos from other channels that could help.

Thank you again for reaching out and for supporting BCH Technologies. I hope the software recovery route works for you (if the USB connection is still active), and if not, at least this gives you a clear explanation of why the printer is stuck and what the realistic next steps look like.
