Epson M1120 — Adjustment Program

The Epson M1120 (a monochrome ink tank printer) does not have a widely publicized "Adjustment Program" in the same way that older cartridge-based Epson models do. However, Epson does provide a "Adjustment Program" (often called a Service Program or Resetter Tool) for technicians.

Key features of this program for the M1120 typically include:

  1. Waste Ink Pad Counter Reset

    • Resets the protection counter after you replace or clean the waste ink pads.
    • Prevents the "Service Required" error (flashing lights, no printing).

  2. Initial Ink Charge

    • Forces the printer to perform the initial ink filling process (used after replacing the ink system or mainboard).

  3. Print Head Nozzle Check & Cleaning

    • More advanced cleaning cycles than the user-mode utility.
    • Can perform powerful head flushing (sometimes called "powerful cleaning" or "ink charge").

  4. EEPROM Backup/Restore

    • Saves/restores printer settings, serial number, and usage counters.

  5. Bi-D Adjustment (Print Alignment)

    • Adjusts bidirectional printing to fix vertical misalignment.

  6. Motor & Sensor Checks

    • Tests the paper feed motor, carriage motor, and various sensors (PW sensor, PE sensor, etc.).

  7. USB ID & Serial Number Input

    • Allows writing the correct USB Vendor ID / Product ID and serial number (useful after mainboard replacement).

Important notes:

If you just want to reset the waste ink counter, you might instead use WIC Reset Utility (paid, but simpler) or find the Adjustment Program on Epson service websites (use with caution).

Once upon a time, in a busy home office, a reliable Epson EcoTank M1120

was the hero of every workday. It churned out reports and invoices without a hitch—until one morning, it suddenly stopped. Two red lights began to blink rhythmically, and a message appeared on the computer screen: "Service Required".

The printer’s internal "odometer"—the Waste Ink Pad Counter—had reached its limit. This counter tracks the ink used during maintenance cycles, and once it's full, the printer locks itself to prevent ink from overflowing onto your desk. epson m1120 adjustment program

This is where the Epson M1120 Adjustment Program (often called a "Resetter") comes into the story. This specialized software acts like a digital key for technicians, allowing them to communicate directly with the printer's brain. The Technical Journey

To bring the printer back to life, the user followed these steps:

Preparation: They ensured the printer was connected via USB (Wi-Fi resets are often unreliable) and temporarily disabled their antivirus, as these utility tools are often flagged incorrectly as threats. Selection : After opening the adjprog.exe file, they selected the model and entered the Particular Adjustment Mode.

The Reset: They navigated to the Waste Ink Pad Counter section. By clicking "Check," they saw the counter sitting at 100%. With a deep breath, they clicked "Initialize".

The Revival: A prompt appeared: "Please turn off the printer." They flicked the switch, waited a few seconds, and turned it back on.

The red lights vanished. The counter was back to 0%, and the was ready to print again. A Cautionary Note

While the software reset the digital counter, it didn't physically clean the ink pads. To truly finish the story and avoid a messy desk, the user eventually replaced or cleaned the physical Waste Ink Pads to ensure the printer remained as reliable as the day they first bought it.

Epson M1120 Adjustment Program (also known as the "AdjProg" or "Resetter") is a specialized maintenance tool designed to service the EcoTank M1120. While primarily used by technicians, it is most commonly sought out by users to resolve the "Service Required"

error, which occurs when the printer's internal waste ink pads are theoretically full. Key Functions of the Program

The utility provides a suite of "Particular Adjustment" modes to diagnose and fix hardware-level issues: Waste Ink Pad Counter Reset

: The primary reason for use. It resets the internal counter to 0% so the printer can resume operation after you have physically cleaned or replaced the ink pads. Print Head Alignment

: Calibrates the print head to fix blurry text or "banding" (white lines) in your mono prints. Ink Charge

: Forces a deep cleaning cycle to prime the ink lines if the printer has been sitting idle for a long time. EEPROM Operations

: Allows for backing up or restoring the printer's core configuration data. How to Use the Utility Before starting, ensure your printer is connected via (Wi-Fi resets are often unstable and can fail). AdjProg.exe . Choose the Waste Ink Pad Counter Reset

model and ensure the specific USB port is selected (don't leave it on "Auto Selection"). : Click on Particular Adjustment Mode Maintenance : Locate and select Waste ink pad counter from the list. Check & Initialize to see your current point usage. Check the boxes for the Main Pad Counter and click Initialization

: A prompt will tell you to turn off the printer. Turn it off, then back on. The error light should now be gone. Important Precautions Physical Maintenance : Resetting the software does

make the ink disappear. If you reset the counter without cleaning or replacing the waste ink pads , ink may eventually leak out of the bottom of the printer. Source Verification

: Be cautious when downloading these programs. Many "free" versions found on forums can contain malware. Always use a reputable service source or official Epson service centers when possible. Compatibility : This specific program is built for the M1100 series

; using it on other models (like the L-series) can corrupt the printer's firmware. Are you currently facing a specific error code , or are you looking for a safe download link for the M1120 resetter? Start Here - M1100/M1120 - Epson

How often can I reset the M1120?

You can reset it indefinitely, but physically, the waste ink pads can only absorb so much. After 3–4 resets, you absolutely must install an external waste ink bottle to prevent leakage, even if the pads look dry.

10. Recommendations (practical best practices)

Summary

This guide evaluates the Epson M1120 adjustment (service) program used for maintenance tasks such as waste pad counter reset, ink charge, firmware or encoder adjustments, and other service functions. It covers purpose, safety/legal considerations, features, typical workflow, reliability, compatibility, risks, detection, alternatives, and recommendations.

Step-by-Step Guide: Using the Epson M1120 Adjustment Program

Once you have a legitimate copy and you have physically maintained your waste ink pads, follow these steps.

⚡ Critical Risks:

  1. Ink Overflow (Real Physical Damage)
    The pads hold a finite amount of ink. If you reset the counter without actually replacing or cleaning the pads, the printer will happily keep printing. Eventually, waste ink will drip out the bottom, ruining desks, carpet, and—most importantly—the printer’s power supply (causing short circuits).

  2. Firmware Bricking
    Using a mismatched version of the adjustment program (e.g., a v1.0 tool on a v1.2 firmware printer) can corrupt the EEPROM. Result? The printer becomes a paperweight.

  3. Voided Warranty
    Epson’s warranty explicitly excludes damage from third-party service software. If your M1120 is under warranty, use the official repair channel.

  4. Malware Risks
    Keygens, crack sites, and torrents hosting the program often bundle trojans, miners, or ransomware. Never run an executable from an untrusted source without an antivirus scan.

Step 4: Reset the Counter

  1. In the same window, check the boxes for Main Pad Counter and Waste Ink Box Counter.
  2. Click Initialization or Reset.
  3. Wait 10 seconds. The program will say “Success” or “Completed.”
  4. Turn the printer off, wait 30 seconds, and turn it back on.

Risks and Warnings

3. Manual Pad Cleaning + EEPROM Reset via Arduino (Advanced)

Hardcore users can open the printer, remove the ink pads, wash/dry them, and use an Arduino + EEPROM reader to rewrite the counter. This is only for electronics hobbyists.
