Epson M2120 Adjustment Program ((new)) May 2026

The Epson M2120 Adjustment Program (also known as the AdjProg or Resetter) is a specialized maintenance utility used to service Epson monochrome EcoTank printers. It is primarily utilized when a printer displays a "Service Required" error, indicating that the internal waste ink pads have reached their theoretical limit. Primary Functions

The program allows users to perform technical adjustments that are typically restricted to authorized service centers:

Waste Ink Pad Counter Reset: Clears the internal counter so the printer can resume operation after the "Service Required" message appears.

Print Head Maintenance: Includes "Deep Cleaning" cycles and "Head ID" settings to ensure optimal print quality.

Mechanical Adjustments: Allows for "Top Margin" and "Bi-Directional (Bi-D)" alignment to fix overlapping or crooked text.

EEPROM Operations: Can be used to back up or initialize the printer's internal settings during a motherboard replacement. How to Use the Adjustment Program To utilize this tool, you generally follow these steps:

Preparation: Connect your Epson M2120 to a computer via a USB cable (Wi-Fi resets are often unreliable) and ensure the printer is powered on.

Selection: Launch the program and click the "Select" button. Choose your specific model (M2120) and the correct USB port.

Adjustment Mode: Click on "Particular Adjustment Mode" to see the full list of maintenance options.

Resetting: For ink pad issues, select "Waste ink pad counter". Check the boxes for the counters (e.g., Main pad counter), click "Check" to see current levels, and then "Initialize" to reset them to zero.

Restart: Once the program confirms the reset, turn the printer off and back on to clear the error. Important Considerations

Hardware Maintenance: Simply resetting the software counter does not remove the physical ink from the pads. To avoid leaks or internal damage, you should physically clean or replace the waste ink pads or install an external waste ink tank.

Software Sources: Many versions of this program found online are third-party tools. Common alternatives include the WIC Reset Utility, which is often easier to use but may require a one-time purchase "key" for the reset function. Reset Epson M2120 Wicreset Key

While Epson recommends professional servicing, many users choose to use the Epson Adjustment Program (Resetter) to clear this error and resume printing. What is the Epson M2120 Adjustment Program?

The Adjustment Program (or "Resetter") is a maintenance tool designed for technicians. It allows you to:

Reset the Waste Ink Pad Counter: Clear the error that blocks printing once the internal sponge is "full."

Initialize Settings: Reset the printer to its factory state.

Maintenance: Perform deep head cleanings or adjust print head alignment. Step-by-Step: How to Reset the Waste Ink Pad Counter

Before starting, ensure your printer is connected to your PC via a USB cable (Wi-Fi resets are often unstable and can fail).

Download and Extract: Download the Epson M2120 Adjustment Program from a reliable source and extract the .zip file to your desktop.

Run the App: Open the folder and run the AdjProg.exe file. If you encounter an error, try right-clicking and selecting "Run as Administrator."

Select Your Model: Click the Select button. Choose M2120 from the Model Name list and ensure the Port is set to Auto Selection or the specific USB port where your printer is connected. Enter Adjustment Mode: Click on Particular Adjustment Mode.

Find the Counter: From the list of maintenance options, select Waste ink pad counter and click OK. Check and Initialize: Check the box next to Main pad counter. Click Check to see the current usage percentage. Click Initialize to reset the counter to zero.

Power Cycle: A pop-up will ask you to turn off your printer. Turn the printer off, click OK on the screen, then turn the printer back on. Important Maintenance Tip

Resetting the software does not physically clean the ink pads. If you reset your printer multiple times without replacing or cleaning the physical waste ink pads, ink could eventually leak and damage the internal components. For high-volume users, the Epson M2120 is a workhorse, but it still requires physical upkeep.

Step-by-Step Usage Guide

While specific interfaces may vary depending on the version of the software, the general process for resetting the waste ink counter is as follows:

  1. Connection: Ensure the printer is connected to the computer via USB and turned on. Ensure the standard printer driver is installed.
  2. Run as Administrator: Right-click the adjustment program executable (often named AdjProg.exe or similar) and select "Run as administrator."
  3. Select Model: In the interface, select the printer model (M2120 or M2110 Series) and ensure the correct USB port is detected.
  4. Maintenance: Click the "Particular adjustment mode" button.
  5. Waste Ink Pad Counter: Select "Waste ink pad counter" from the list of maintenance options.
  6. Check and Reset: Click "Check" to see the current counter values. Select the "Main pad counter" box and click "Initialization."
  7. Finish: A confirmation window will appear. Click OK. The printer will perform a brief internal operation.
  8. Power Cycle: Turn the printer off, wait a few seconds, and turn it back on. The error should be cleared.

How It Works

The software communicates directly with the printer's firmware via a USB connection. It bypasses the standard print spooler used by Windows or macOS, sending direct commands to the printer's logic board.

8. Practical recommendation (concise)

Prioritize official support and authorized repair. Use third‑party adjustment programs only as a last resort on printers you own, after backing up settings and verifying the tool’s source; accept the risk of voided warranty and potential hardware damage.

Step 4: Final EEPROM Update

  1. Go back to the main menu.
  2. Click "EEPROM Data Copy" -> "Update EEPROM".
  3. This solidifies the reset so it survives a power cycle.
  4. Turn the printer off, wait 30 seconds, turn it back on normally.

Your "Service Required" error should be gone.

1. Waste Ink Pad Counter Full (Service Required Error)

The most common reason users search for the Epson M2120 Adjustment Program is the dreaded "Service Required" or "A printer’s internal component is at the end of its service life" message. This happens after the printer has performed thousands of cleaning cycles. The waste ink pads absorb excess ink, and the printer tracks this via a digital counter.

Without the adjustment program, you cannot reset this counter. Even if you physically replace the pads or install an external waste tank, the printer will remain locked until the counter is reset via the software.
