chaotic firmware update Epson ET-2750

The regular firmware update of my printer ended in a seemingly bricked machine.

Neither in the manual nor in the online portal this problem was mentioned.

I found several posts in forums and groups, no solution was offered.

But … a long search session later there was one anonymus post which solved my problem:

Error message:

„Printer Mode

Set Jig

Push [OK] BT“

Unplugging the printer and various other voodoo doesn’t work, but I found a way to force it to technician mode.

Make sure the unit is off.

Then, while holding down the Home button, press the BT button for a few seconds. Eventually, you’ll get a screen with 4 options on it.

Go to 4, Normal mode.

On my machine, it defaulted to Japanese, which I don’t read like I suspect most of you don’t either. To Change the Language:

  1. You need to go the Gear icon (Settings) and hit OK on the control panel.
  2. Right arrow on the control panel once (to 2 / 10)
  3. Click OK
  4. Right arrow on the control panel 3 tunes (to 4 / 8)
  5. Find your language on the list by using the up and down arrows on the control panel
  6. Click OK

I had to reset my printer to work with my network by going to the WiFI Setup.

I then found the Print Network settings option on the printer and printed out the details so I’d have them when I finished setting up the printer on my PC.

Once that was done, I had to go to my PC (Windows 10-64 bit OS) and go to Printer Properties to find and install a „new“ printer.
