Epson L120 Waste Ink Pad Counter – Meaning, Symptoms, and Reset Guide
Epson L120 Waste Ink Pad Counter – Meaning, Symptoms, and Reset Guide
As a long-time Epson L120 user, I remember how worried I was when my printer suddenly stopped working in the middle of an important task. The green power light and red paper/ink light started blinking alternately, and a Service Required message appeared on my computer screen.
At first, I thought my printer had suffered a permanent failure. However, after researching the technical details, I learned that the problem could be related to the Waste Ink Pad Counter. This system tracks estimated waste ink accumulation and can stop printing when its programmed limit is reached.
In this guide, I will explain what the waste ink pad counter does, the symptoms I encountered, and the steps involved in resetting the counter and addressing the physical waste ink pad. My goal is to help other Epson L120 users understand the problem and make informed decisions before paying for a repair.

1. What Is the Waste Ink Pad Counter?
When I first encountered this issue, I did not realize that a printer produces waste ink during certain operations. Whenever the printer performs tasks such as printhead cleaning, some ink is directed into an internal waste ink collection system.
The Epson L120 uses a digital counter to estimate waste ink accumulation. The waste ink pad absorbs this ink, while the counter tracks usage according to the printer's internal system.
When the counter reaches its programmed limit, the printer may stop printing and display a service-related warning. This mechanism helps prevent the printer from continuing to operate indefinitely as the waste ink collection system approaches its service limit.
It is important to understand that the counter is an estimate, not a direct measurement of how much ink the pad physically contains. The actual condition of the pad may vary depending on printer usage and maintenance history.

2. Symptoms I Noticed Before Resetting the Printer
Before I could use my Epson L120 again, I noticed several warning signs that helped me identify the possible cause.
Alternating Indicator Lights
The green power light and red paper/ink indicator blinked alternately. This behavior can be associated with a service-related condition, although other printer errors should also be considered when diagnosing the problem.
A Service Required Message
My computer displayed the following warning:
Service Required: A printer's ink pad is at the end of its service life. Please contact Epson Support.
This message indicated that the printer had reached an ink pad service limit and required further attention.
Printing Commands Were Rejected
The printer stopped accepting normal printing jobs, even though paper and ink were still available. This helped me understand that the problem was not necessarily caused by an empty ink tank or a lack of paper.
If you encounter similar symptoms, I recommend checking the exact error message and indicator pattern before attempting a reset.
3. How to Reset the Epson L120 Waste Ink Pad Counter
After identifying the possible cause, I researched how the counter could be reset using an Epson-compatible Adjustment Program, commonly referred to as AdjProg.
The process involves two separate considerations: resetting the electronic counter and addressing the physical waste ink collection system.
Important Before You Start
Resetting the counter does not remove waste ink from the printer. If the waste ink pad is saturated, resetting the counter without inspecting or servicing the pad may allow ink to overflow and potentially damage the printer or surrounding surfaces.
Check the pad's condition and arrange appropriate maintenance before returning the printer to regular use. If you are unfamiliar with printer disassembly, consider using a qualified technician.
Stage 1: Software Reset Using the Adjustment Program
Step 1: Prepare a Compatible Adjustment Program
I looked for an Adjustment Program specifically compatible with the Epson L120. Before using any downloaded utility, verify its source, compatibility, and safety.
Some unofficial utilities may trigger antivirus warnings. However, an antivirus detection should never automatically be assumed to be a false positive. Scan downloaded files and avoid unknown executables or programs that require disabling security protection.
Step 2: Connect the Printer to Your Computer
I connected the Epson L120 to my computer using a USB cable and ensured that the printer was powered on and properly recognized.
I then opened the compatible Adjustment Program and checked that the selected printer model was L120.
The available menus and behavior may differ between program versions, so the exact interface may not match every tutorial.

Step 3: Open the Maintenance Menu
In the version of the utility I used, the maintenance options were available through a menu called Particular Adjustment Mode.
I located the Main Pad Counter option and opened it to review the available counter functions.
Step 4: Check the Counter Status
I selected the relevant counter option and used the available checking function to review its status.
If the counter has reached its limit, the utility may provide an initialization option. However, the displayed percentage and available controls can vary by software version.
Before proceeding, make sure you understand which counter is being modified and that the physical waste ink collection system has been appropriately inspected or serviced.
Step 5: Initialize the Counter and Restart
If the appropriate maintenance has been completed and the utility supports the procedure, follow its instructions to initialize the relevant counter.
After the operation, restart the printer as instructed by the software. Check whether the warning has cleared and whether the indicator lights have returned to their normal state.
Clearing a warning should not be treated as proof that the printer's internal waste ink system is clean or safe.
4. How to Handle the Physical Waste Ink Pad
After learning about the counter, I realized that the physical waste ink collection system deserved just as much attention as the software.
Inspect the Waste Ink Collection System
The waste ink pad is located inside the printer and absorbs ink discharged during certain maintenance operations. Accessing it may require partial disassembly.
I recommend following a reliable service manual or asking a qualified technician to inspect the pad. Incorrect disassembly can damage plastic components, cables, or other internal parts.
Cleaning or Replacing the Pad
If the pad is saturated or damaged, cleaning or replacement may be necessary, depending on its condition and the recommended service procedure.
Simply rinsing a saturated pad and reinstalling it is not always an appropriate repair. The pad must be handled safely and allowed to dry completely if the approved procedure permits cleaning. Ink-contaminated wastewater should also be disposed of responsibly rather than poured directly into drains.
For a reliable long-term solution, replacement with a suitable component may be preferable to attempting to reuse a heavily saturated pad.
Considering an External Waste Ink Container
Some printer users consider redirecting waste ink into an external container. Although this modification may reduce the need to access the internal pad, it changes the printer's original waste ink arrangement.
I would not recommend this modification without understanding the printer's internal tubing, the risks of leaks, and the need for secure, compatible connections. An improperly installed container can create additional maintenance problems.
For most users, inspecting and servicing the original waste ink collection system is the more straightforward approach.

5. What If the Service Required Error Returns?
If the Epson L120 displays the same warning after maintenance, I recommend checking the following possibilities:
- The counter reset did not complete successfully.
- The Adjustment Program is incompatible with the printer or operating environment.
- The physical waste ink pad still requires service.
- Another printer error is causing the warning or preventing normal operation.
- The printer requires additional diagnosis by a qualified technician.
Avoid repeatedly resetting the counter without identifying why the warning has returned. Repeated resets do not eliminate accumulated waste ink and may conceal a maintenance issue.
6. Frequently Asked Questions
What does the Epson L120 Waste Ink Pad Counter mean?
It is an internal counter that estimates waste ink accumulation. When its programmed limit is reached, the printer may stop printing and display a service-related warning.
Can I reset the Epson L120 without replacing the waste ink pad?
The electronic counter may be reset separately from physical pad maintenance, depending on the compatible utility and the printer's condition. However, if the pad is saturated, resetting the counter alone does not resolve the physical problem.
Does the waste ink pad counter measure the actual amount of ink?
No. The counter estimates waste ink usage based on the printer's internal tracking system. It does not directly measure the amount of ink physically stored in the pad.
Is the Epson L120 Adjustment Program safe to download?
Safety depends on the source and the specific file. Use a trustworthy source, scan downloads before opening them, and avoid disabling antivirus protection simply to run an unknown utility.
Should I clean or replace the waste ink pad?
That depends on its physical condition and the applicable service procedure. If the pad is saturated, damaged, or leaking, professional inspection and suitable replacement may be the safer option.
7. Conclusion
My experience with the Epson L120 taught me that a Waste Ink Pad Counter warning does not automatically mean the printer is permanently broken. It can indicate that the printer has reached a programmed maintenance limit, but the underlying condition still needs to be checked.
Understanding the warning, using compatible maintenance software, and addressing the physical waste ink collection system are all important parts of the process.
If your Epson L120 displays a Service Required message, take the time to diagnose the cause before resetting the counter. With the right maintenance approach, you can make a more informed decision about restoring your printer and keeping it in reliable working condition.
