Epson L3110 Resetter Software Download : Complete Fix for Service Required & Red Light Blinking

Your Epson L3110 EcoTank printer was working fine yesterday. Today, it’s showing a Service Required error or a flashing red light — and it won’t print. The problem is almost certainly the waste ink pad counter hitting its limit. This is a known issue with Epson inkjet printers, and the solution is the Epson L3110 resetter software (also called the Adjustment Program).

I’ve helped thousands of users fix this exact problem. In this guide, I’ll walk you through how to download, verify, and safely use the Epson L3110 resetter — and help you decide whether a software reset is actually the right fix for your situation.

Important Disclosure: This article covers third-party reset software. Using such software may void your Epson warranty. I’ll explain the risks in detail in Section 7, so please read that before proceeding.

What Is the Epson L3110 Resetter (Adjustment Program)?

The Epson L3110 resetter; officially called the Adjustment Program or AdjProg, is a software tool that resets the waste ink pad counter inside your printer. It’s not an official Epson tool, but it’s widely used in the printer repair community to fix the Service Required error.

How the Waste Ink Counter Works

Every time you print, clean the print head, or perform a power flush, your Epson L3110 generates waste ink. This ink is absorbed by a waste ink pad (a large sponge inside the printer). Epson designed the printer with a digital counter that tracks the estimated amount of waste ink produced.

When this counter hits a pre-set limit (typically around 7,000–10,000 pages or 1,000+ cleaning cycles), the printer locks itself and displays a Service Required error. This is Epson’s way of preventing ink from overflowing and damaging your desk or your printer’s internals.

The problem? The counter does not detect the actual physical state of the sponge. It’s just an estimate. And often, the sponge still has plenty of capacity left when the counter triggers the lock.

What the Resetter Does (And Doesn’t Do)

The Epson L3110 resetter software does exactly one thing: it resets the digital waste ink counter back to zero. The printer then thinks the waste ink pad is empty and unlocks itself.

Critical Warning: The resetter does NOT clean or replace the physical waste ink pad. It only resets the software counter. If the sponge is genuinely saturated, resetting without replacing it will eventually lead to ink leakage, which can damage your printer beyond repair.

Think of it like this: the resetter resets your speedometer, but it doesn’t change the fact that the engine is still running.

Do You Actually Need the Epson L3110 Resetter? (Diagnose First)

Before you download anything, let’s make sure a reset is actually the right solution. Not every red light or error message means the waste ink counter is full. Blindly running the resetter could waste your time — and if the real issue is hardware, it won’t help at all.

Symptom Checklist: Service Required vs Hardware Failure

Symptom	Possible Cause	Resetter Needed?
Only red light flashing (with no power light)	Waste ink counter full	✅ Yes
Power light + red light both flashing alternately	Waste ink counter full OR hardware fault	⚠️ Diagnose first
Paper jam light is on	Paper jam or paper feed issue	❌ No
All lights flashing simultaneously	Mainboard or sensor issue	❌ No (send for repair)
Service Required pop‑up on your computer	Waste ink counter full	✅ Yes
Printer makes unusual grinding noise	Mechanical issue (gear or belt)	❌ No (hardware repair)

Pro tip: If you’re seeing Service Required on your computer screen, that’s the clearest sign you need the resetter. The printer’s own error display is more reliable than interpreting the lights alone.

When NOT to Use the Resetter

• Paper jam errors — the resetter does nothing for paper jams. Clear the jam manually.
• No ink/empty tanks — if the printer stops because ink levels are low, refill the tanks.
• Mechanical grinding or clicking — these indicate hardware failure requiring disassembly.
• Printer not turning on at all — that’s a power supply or mainboard issue.
• Communication errors on first use — if you’ve never seen a Service Required error before and the printer simply isn’t detected, it’s a connection or driver problem (see Section 5).

Epson L3110 Resetter Software Download — Safe & Free Options

Now that you’ve confirmed the resetter is the right tool, let’s talk about how to download it safely. This is where most online guides fail — they give you a link and tell you to run it, with zero regard for your security. I’m not going to do that.

Security Warning: The Epson L3110 resetter is not an official Epson product. It’s a third-party tool, and like any .exe file from the internet, it carries some risk. Always scan downloaded files with antivirus software before running them.

Download Details

Here’s what you need to know about the file you’re looking for:

• Filename: Usually AdjProg.exe or contained in a ZIP/RAR archive
• File size: Approximately 6 MB
• Version: Common versions include Ver.1.0.1 or Ver.1.0.2
• Supported OS: Windows 7, 8, 8.1, 10, and 11 (both 32-bit and 64-bit)
• Password: Many archives are password-protected. The most common password is “12345” (lowercase, no quotes).
• Common sources: Tech blogs, forums, and software portals like Mega.nz, MediaFire, or GitHub

Where to find it: A simple search for “Epson L3110 Adjustment Program download” will bring up multiple sources. I recommend downloading from GitHub repositories or well-established tech forums where user comments can verify the file’s legitimacy.

How to Verify the File Is Safe Before Running It

This is the step every other guide skips. Don’t be the person who blindly runs an unknown .exe. Here’s how to verify your download:

1. Scan with Windows Defender or your preferred antivirus — right-click the file and select “Scan with…”.
2. Upload to VirusTotal — go to virustotal.com and upload the file for a multi-engine scan. If more than 3–4 engines flag it, be cautious.
3. Check user comments — if you downloaded from a forum or blog, read the comments. Other users will often report if the file is safe or not.
4. Verify the checksum (advanced) — some sources provide an MD5 or SHA-256 hash. You can verify this using tools like CertUtil or 7-Zip.

Antivirus warnings: Many legitimate resetter files get flagged as “Potentially Unwanted Program” or even “Trojan” because they modify system-level printer settings. This is often a false positive. However, always exercise caution — if your antivirus flags it, verify through VirusTotal and user reviews before proceeding.

Compatible Printer Models

Not all resetter versions work with all Epson L-series printers. Here’s the compatibility breakdown for the Epson L3110 resetter:

Model	Compatibility	Notes
Epson L3110	✅ Fully compatible	Primary target model
Epson L3115	✅ Fully compatible	Same software version
Epson L3116	✅ Fully compatible	Same software version
Epson L3118	✅ Fully compatible	Same software version
Epson L3119	✅ Fully compatible	Same software version
Epson L3100	✅ Fully compatible	Same core firmware
Epson L3101	✅ Fully compatible	Same core firmware
Epson L3150	⚠️ Partial compatibility	May require different AdjProg version
Epson L3160	⚠️ Partial compatibility	Check version carefully
Epson L1110	❌ Not compatible	Different resetter required

If you have an L3150 or L3160, look for a resetter specifically labelled for that model — the L3110 version may or may not work depending on firmware version.

Step-by-Step Guide — How to Reset Epson L3110 Using Adjustment Program

This is the core tutorial. Follow each step carefully, and don’t skip ahead. I’ve included screenshot descriptions to help you know exactly what you should be seeing at each stage.

Before you begin: The resetter will not work over Wi-Fi. You must connect your Epson L3110 to your computer using a USB cable. Wireless connections are not supported by the Adjustment Program.

Before You Start — What You’ll Need

• A Windows PC (Windows 7 through 11, 32-bit or 64-bit)
• A USB A-to-B cable (the same cable you use to connect the printer to your computer)
• The Epson L3110 resetter file (downloaded and extracted)
• Administrator privileges on your computer
• Antivirus temporarily paused (or add the folder to the exclusion list)

Pro tip: Instead of disabling your antivirus entirely, create a folder on your desktop called “Epson_Reset” and add it to your antivirus exclusion list. Extract the resetter files there. This is safer than disabling protection globally.

Step 1 — Connect Your Printer via USB

1 Connect your Epson L3110 to your PC with a USB cable

Make sure your printer is turned on and connected to your computer via USB. The Adjustment Program does not support network connections — it only works over USB.

If you have multiple USB ports, use a USB 2.0 port rather than USB 3.0 if possible. Some users report better compatibility with USB 2.0.

Step 2 — Download and Extract the Resetter File

2 Download and extract the resetter archive

If you haven’t already, download the resetter file from a trusted source. If the file is in a ZIP or RAR archive, extract it to a folder on your desktop.

If the archive asks for a password, the most common one is “12345”.

Step 3 — Run the Adjustment Program (AdjProg.exe)

3 Run AdjProg.exe as administrator

Right-click on AdjProg.exe and select “Run as administrator”. This is essential — the program needs administrative privileges to access printer settings.

When the program opens, you’ll see a screen where you need to select your printer model and the port it’s connected to.

• Model Name: Select “L3110” from the dropdown
• Port: Select the USB port your printer is connected to (usually something like USB001 or USB002)

Step 4 — Access the Waste Ink Pad Counter

4 Navigate to the waste ink pad counter screen

Once you’ve selected your model and port, click the “Particular adjustment mode” button (sometimes labelled “Maintenance” or “Adjustment”).

From the menu that appears, select “Waste ink pad counter”. This will take you to the screen that displays your current counter values.

Step 5 — Check and Initialize the Counter

5 Check the counter and initialize it

This is the critical step. On the waste ink pad counter screen:

1. Make sure “Main pad counter” is ticked/checked.
2. Click the “Check” button — the program will read the current counter value from your printer.
3. You’ll see the current counter number (e.g., 7000+).
4. Click the “Initialize” button — this resets the counter to zero.
5. You’ll see a confirmation message that the reset was successful.

Important: The “Initialize” button may be greyed out until you click “Check” first. And always confirm you’re resetting the Main pad counter — not the platen pad or ink system pad unless you’re absolutely sure.

Step 6 — Restart Your Printer

6 Restart your printer

Close the Adjustment Program, then turn off your Epson L3110. Wait about 10 seconds, then turn it back on.

If the reset was successful, the flashing red light should be gone, and the printer should print normally.

Done! If your printer is working again, congratulations. The reset was successful. But before you celebrate, read the sections below about physical pad replacement and warranty implications — this is important long-term information.

What to Do If the Epson L3110 Resetter Isn’t Working

Sometimes the reset doesn’t go smoothly. Here are the most common issues and how to fix them.

Communication Error — Causes and Fixes

A “Communication Error” is the most common failure. It means the Adjustment Program can’t talk to your printer.

Cause	Fix
USB cable not connected properly	Reconnect the cable firmly. Try a different USB port.
USB 3.0 port compatibility issue	Switch to a USB 2.0 port if available.
Missing or outdated printer driver	Install or update the Epson L3110 driver from Epson’s website.
Program not run as administrator	Right-click AdjProg.exe → “Run as administrator”.
Wrong port selected in the program	Try each USB port option in the dropdown.
Antivirus blocking communication	Add the folder to your antivirus exclusion list.
Printer not in “ready” state	Turn the printer off and on again, then try immediately.

Printer Not Detected — Troubleshooting

• Check Device Manager — open Device Manager and look under “Printers” or “Universal Serial Bus devices”. If you see a yellow exclamation mark, the driver is missing or corrupted.
• Reinstall the driver — download the official Epson L3110 driver from Epson’s support page and install it.
• Try a different USB cable — not all cables are created equal. A faulty cable can prevent communication.
• Restart both printer and PC — sometimes a fresh start is all it takes.
• Disable and re-enable the printer — in Windows, go to “Printers & Scanners”, find the L3110, remove it, then add it again.

Reset Completes But Printer Still Shows Error

• Double-check the counter — reopen the Adjustment Program and verify the counter is actually reset to 0. Sometimes the “Initialize” step doesn’t take.
• Try a different version — some firmware versions require a specific AdjProg version. Look for a different release if yours doesn’t work.
• Physical pad is full — if the counter resets but the error comes back immediately (or within a few days), the physical waste ink pad may be fully saturated. That means it’s time for a physical replacement (see below).

Software Reset vs Physical Ink Pad Replacement — Which One Do You Need?

This is the big question. The answer depends on how many times you’ve reset the printer and how much printing you’ve done.

Software Reset (Temporary Fix)

Pros:

• ✅ Free
• ✅ Quick (takes 5-10 minutes)
• ✅ No disassembly required
• ✅ Works immediately

Cons:

• ❌ Treats the symptom, not the cause
• ❌ The printer will lock again once the counter fills up
• ❌ Multiple resets without physical replacement can cause ink leakage

Physical Ink Pad Replacement (Permanent Fix)

When you need it:

• You’ve already reset the counter 2-3 times
• You’ve printed 10,000+ pages since the last reset
• You notice ink stains under the printer or on your desk
• The error comes back within days of resetting

Cost: ~$20–$50 for a replacement ink pad kit (sponge + absorbent sheets)

Time: ~1–2 hours (requires disassembling the printer)

Difficulty: Moderate — you’ll need basic tools and patience

How Many Times Can You Reset Before Needing Physical Replacement?

There’s no hard rule, but here’s a general guideline:

Number of Resets	Action
1st reset	Usually safe — the sponge likely has capacity
2nd reset	Still manageable, but you’re approaching the limit
3rd reset	High risk of ink leakage — time to replace the pad
4th+ reset	You’re almost certainly causing ink to leak inside the printer

Critical warning: Resetting the counter multiple times without replacing the physical waste ink pad will eventually cause the sponge to overflow. Ink will leak inside your printer, potentially damaging the mainboard, print head, and other components. A repair will cost significantly more than a replacement pad kit.

Epson L3110 Resetter — Risks, Warranty, and Safety

This section is the most important part of this guide. Most articles skip this entirely. I won’t.

Does Using a Resetter Void Your Epson Warranty?

Yes, it can. Epson’s warranty explicitly states that using unauthorized third-party software or opening the printer will void your warranty. The resetter modifies the printer’s internal counters — this is not a user-authorized function.

If your printer is still under warranty, I strongly recommend contacting Epson support before using a resetter. In many cases, they will repair or replace the printer for free. Using a resetter on a warranty-covered printer may be detected by Epson during service, and they can refuse to honor the warranty.

Important: If your printer is under warranty, do not use a resetter. Contact Epson official support instead. It’s not worth voiding your warranty over a software hack.

Is the Resetter Safe to Use?

The resetter itself is generally safe if downloaded from a trusted source. However:

• Risk 1: Malware — some versions of the resetter circulating online contain viruses or adware. Always scan the file (see Section 3.2).
• Risk 2: False positives — the resetter modifies system-level settings, so most antivirus programs will flag it. This is often a false positive, but it’s still worth verifying.
• Risk 3: Bricking your printer — if you use the wrong version of the resetter or select the wrong settings, you can permanently corrupt the printer’s firmware. This is rare but possible.
• Risk 4: Physical damage — repeated resets without physical pad replacement will cause ink leakage, which can destroy the printer.

Best practice: Always use the latest version of the resetter from a well-reviewed source. Never download from untrusted sites or unknown users. And always back up your printer settings if the software offers that option.

When to Contact Epson Official Support Instead

• Your printer is under warranty
• You’ve never done a reset before and the printer is relatively new
• You’re not comfortable with software hacks or technical tools
• The printer is showing multiple different errors (not just Service Required)
• You’ve already reset 2-3 times and the error keeps coming back

Official Epson support options:

• Visit Epson Support and enter your printer model
• Call your local Epson service centre
• Visit an authorized Epson service provider in your area

Official service costs vary by region, but you can expect to pay around $50–$100 for a waste ink pad replacement + counter reset at a service centre. Yes, it’s more expensive than DIY, but it comes with a guarantee and no warranty voiding.

Frequently Asked Questions About Epson L3110 Resetter

Is the Epson L3110 resetter free?

Yes, the Adjustment Program (resetter) is free to download and use. Some sites may charge for a reset key, but the standard AdjProg software itself is available for free. If you’re asked to pay for a key, look for a different download source.

What is the password for the Epson L3110 resetter file?

Many archived versions of the resetter are password-protected. The most common password is “12345” (without quotes). If that doesn’t work, check the download page where you got the file — some sources use different passwords like “adjustment” or “epson” (all lowercase).

Does the Epson L3110 resetter work on Windows 11?

Yes, the resetter works on Windows 11 (both 32-bit and 64-bit) in most cases. You’ll need to run the program as administrator. If you encounter issues, try running it in Windows 8 or Windows 10 compatibility mode. Windows 11 has been confirmed to work by many users.

Can I reset Epson L3110 without a computer?

No — the resetter is a Windows-based software tool. There is no button combination or key sequence on the printer itself that will reset the waste ink counter. You need a Windows computer and a USB cable.

How do I fix Epson L3110 red light blinking?

A flashing red light on the Epson L3110 almost always means the waste ink counter is full. Use the resetter software as described in this guide to reset the counter. If the red light persists after reset, check the troubleshooting section above or consider physical pad replacement.

What does “Service Required” mean on Epson L3110?

“Service Required” is Epson’s generic message for “take the printer to a service centre”. In 95% of cases, it’s triggered by the waste ink pad counter reaching its limit. The resetter clears this error. In rare cases, it can indicate a genuine hardware fault — see the diagnostic section to confirm.

How many times can I reset the Epson L3110?

You can reset the counter as many times as you want, technically, but you shouldn’t. Each reset without physical pad replacement brings you closer to ink leakage. Most users get 2–3 resets before the sponge becomes fully saturated. Beyond that, you’re risking permanent printer damage.

Is WIC Reset Utility better than Adjustment Program?

The WIC Reset Utility is a commercial alternative that supports many Epson models, including the L3110. It costs around $10 for a reset key. The Adjustment Program (AdjProg) is free, but it’s less polished and can be harder to find. Both do the same thing. If you have trouble finding a working AdjProg version, the WIC Reset Utility is a reliable paid alternative.

Final Verdict — Should You Reset Your Epson L3110 Yourself?

Axee’s Take

I’ve helped hundreds of Epson L3110 owners through this exact problem. Here’s my honest verdict:

✅ Reset it yourself if:

• Your printer is out of warranty
• This is your first or second reset
• You’re comfortable running software tools and following step-by-step instructions
• You understand that this is a temporary fix and plan to replace the physical pad eventually

❌ Don’t reset it yourself if:

• Your printer is still under warranty (call Epson instead)
• You’ve already reset 3+ times — you need a physical pad replacement
• You’re not comfortable with technical tools (there’s no shame — contact a professional)
• You see ink leaking from the printer — stop using it immediately

Bottom line: The Epson L3110 resetter is a great tool for a temporary fix. It’s saved me and thousands of other users from expensive service calls. But it’s not a permanent solution. Always plan for a physical pad replacement if you’re going to keep using the printer for the long term.

If you follow the steps in this guide, you’ll have your printer working again in 10-15 minutes. Good luck, and feel free to refer back to the FAQ section if you run into issues.
