How to Update Epson Printer Firmware Safely – Firmware updates are essential for keeping your Epson printer running smoothly, improving compatibility, fixing bugs, and even enhancing print quality. However, updating printer firmware—especially on models like Epson EcoTank, WorkForce, or Expression series—must be done carefully. One wrong step could lead to errors, compatibility issues, or even render third-party cartridges unusable.
In this guide, you’ll learn how to update your Epson printer firmware safely, step-by-step, across Windows, macOS, and via mobile tools. You’ll also learn precautions to avoid common pitfalls.
What Is Epson Printer Firmware and Why Does It Matter?
Firmware is the internal software that controls your printer’s hardware operations. It governs everything from ink detection and printhead movement to error handling and wireless connectivity.
Benefits of Updating Firmware:
- Fixes known bugs or system crashes
- Enhances printer performance and response time
- Adds support for new paper types or connectivity features
- Improves compatibility with newer operating systems
- Increases security against vulnerabilities
Warning: Some firmware updates can block third-party ink cartridges. Always read update notes before proceeding.
How to Check Current Firmware Version
Before updating, you need to know what firmware version your printer is running.
Option 1: Via Printer Control Panel
- Press the Home button
- Navigate to Settings > Firmware Info > Version Info
- Note the current firmware version (e.g., NX104U1)
Option 2: Using Epson Software Utility
- Open Epson Printer Utility / Epson Software Updater
- Select your printer
- The utility will display the current version and available updates

This is particularly useful for EcoTank and Expression Home models.
Common Mistakes to Avoid When Updating Firmware
| Mistake | Why It’s Risky |
|---|---|
| Turning off printer during update | May corrupt the firmware and brick the printer |
| Using wrong firmware for different model | Can cause full system failure |
| Updating over unstable Wi-Fi connection | Risks incomplete installation |
| Skipping backup of old firmware | No way to revert if new update causes problems |
| Not checking cartridge compatibility | Might block third-party inks permanently |
Always read Epson’s release notes before proceeding.
How to Downgrade Epson Firmware (If Needed)
If the new firmware causes problems—like rejecting third-party ink—you may need to roll back to a previous version.
Note:
Downgrading firmware is not officially supported by Epson and may void your warranty.
Steps (Advanced Users Only):
- Search for the previous firmware version from a trusted forum or support thread
- Disable automatic firmware updates on printer/software
- Connect printer via USB only
- Run the older firmware package (if available)
- Proceed with installation like a normal update
⚠️ Use tools like WIC Reset Utility or Epson Adjustment Program at your own risk.
How to Disable Auto Firmware Updates
To prevent unwanted updates that may block third-party cartridges:
On the Printer (if available):
- Go to Settings > Firmware Update Settings
- Select Off or Manual Check
Via Epson Software Updater:
- Open the tool
- Click Automatic Update Settings
- Set to Never or Notify Only
This gives you control over when and how updates occur.
Firmware Update Best Practices
| Tip | Why It Matters |
|---|---|
| Always use a stable internet connection | Prevents incomplete or failed updates |
| Keep USB cable connected during process | Reduces risk of wireless interruptions |
| Update only when necessary | Prevents unintentional feature limitations |
