Epson Printer Stuck in "Printer Mode Set Jig" Error - Causes and Fixes

Question:
My Epson printer shows the error message "#1 Solution: Epson Stuck in Printer Mode Set Jig - Push [OK] BT." Previously, I was able to fix this issue with the method you showed, but now it no longer works. It seems the printer updated itself again. Do you have any advice?

Answer:

The "Set Jig" error usually points to a corrupted EEPROM, which is the chip where your printer's firmware is stored. Let me explain a bit about what's happening and the options you have for fixing it:

Why the Set Jig Error Appears

• In Epson's factory, the Set Jig mode is used for testing printers before all the components are installed. Once the printer leaves the factory, this flag is normally cleared.

• When this error reappears, it generally means the EEPROM data is corrupted. Corruption can happen due to firmware updates or internal memory degradation.

• Essentially, the printer gets stuck in a state where it believes it's still in factory testing mode.

Possible Solutions

1. Restart in Service Mode & Reload Firmware

   • Try restarting your printer in service mode and install Epson's recovery firmware to overwrite the corrupted data.

   • This method essentially refreshes the software layer without replacing the EEPROM contents.

2. Use WICReset Tool

   • WICReset software can sometimes help by allowing you to roll back to an earlier firmware version.

   • This is useful if the issue appeared after a recent auto-update.

3. EEPROM Reprogramming (Advanced Option)

   • If the firmware overwrite doesn't work, the corruption may be deeper in the EEPROM.

   • Search for a binary dump file (keywords: "bin dump" + your printer model) on bchtechnologies.com (https://bchtechnologies.com) or other printer repair forums.

   • You'll need to either build an EEPROM programmer yourself or purchase one from Amazon. With this, you can physically write the bin dump back into the memory chip.

   • In some cases, if the EEPROM is badly damaged, replacing the memory chip entirely is the best long-term fix.

Important Notes

• This fix is not guaranteed to last forever. If your EEPROM continues to degrade or more corruption occurs, the "Set Jig" workaround may stop working entirely.

• If your printer is mission-critical, it may be worth weighing the repair cost against the reliability of replacing the unit.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. For this reason, we're not able to provide detailed remote troubleshooting or step-by-step repair instructions. However, we do offer an in-person evaluation and repair service at our diagnostic facility (https://bchtechnologies.com/printer-repair-service). Because of high demand, we operate on a first-come, first-served basis, and it may take a few weeks before we can work on your printer. Our services cover both complete printer repairs and component-level fixes, but we understand our pricing may not be the most economical.
