Last Updated: July 22, 2026
If your Epson printer shows a “Service Required” message, flashing warning lights, or a notice saying the ink pad is at the end of its service life, the printer’s internal waste ink protection counter may have reached its preset limit.
The Epson Adjustment Program, also known as an Epson resetter or AdjProg.exe, is a model-specific maintenance utility commonly used to check and reset the waste ink pad counter on supported Epson printers.
One adjustment program does not work with every Epson printer. You must use the version designed for your exact model. Using an incompatible utility may cause printer-detection problems, communication errors, unsuccessful initialization, or access to settings that are not intended for your device.
This guide explains how the Epson Adjustment Program works, how to find the correct resetter, how to reset the waste ink counter safely, what to do when the software does not detect your printer, and why physical waste ink pad maintenance may still be required.
Important: Resetting the counter does not clean or replace the physical waste ink pads. Stop using the printer and arrange proper maintenance if ink is leaking from the bottom or accumulating inside the machine.

What Is the Epson Adjustment Program?
The Epson Adjustment Program is a service and maintenance utility created for specific Epson printer models or model groups. It provides access to selected functions that are normally unavailable through the standard printer driver or Epson Status Monitor.
Depending on the program version and supported printer, available functions may include:
- Checking the waste ink pad counter value
- Resetting the main waste ink protection counter
- Resetting a platen or borderless-printing counter
- Clearing certain counter-related service lock conditions
- Selecting the printer model and USB port
- Running maintenance or diagnostic checks
- Accessing EEPROM or printer identification settings
- Performing selected alignment or service adjustments
The executable file is often named AdjProg.exe. Although different reset packages may use the same filename, they do not necessarily support the same printers.
What the Adjustment Program Can Fix
The utility may restore printer access when printing has been blocked because the internal waste ink protection counter reached its programmed limit.
It may help with messages such as:
- Service Required
- A printer’s ink pad is at the end of its service life
- Waste ink pad counter overflow
- Parts inside your printer are nearing the end of their service life
- The printer’s ink pads need service
What the Adjustment Program Cannot Fix
An Epson resetter is not a complete hardware-repair tool. It cannot:
- Replace or clean saturated waste ink pads
- Repair a damaged printhead
- Remove a physical paper jam
- Fix a broken USB port or mainboard
- Repair a scanner, motor, sensor, or carriage fault
- Stop ink leakage caused by physical saturation
- Resolve every flashing-light error
If the printer continues to display an error after the correct reset procedure, the problem may involve hardware, driver communication, the physical waste ink system, or an unsupported utility.
Why Epson Printers Show “Service Required”
Epson inkjet printers use ink during printhead cleaning, initial ink charging, nozzle maintenance, and borderless printing. A portion of that ink is directed into an internal absorption system commonly called the waste ink pad.
The printer usually estimates how much ink has entered the waste system through an internal counter. When that calculated value reaches a preset protection limit, the printer may stop normal operation to reduce the risk of internal ink overflow.
Common Causes
- Long-term or high-volume printer use
- Frequent automatic or manual head cleaning
- Repeated power cleaning or ink flushing
- Borderless photo printing
- Initial ink charging
- A waste ink counter reaching its programmed limit
Why the Error May Return After Resetting
A software reset changes the stored counter value. It does not remove the ink already absorbed by the physical pads.
The error or related problems may return when:
- The wrong counter was selected
- The initialization did not complete
- The adjustment program does not fully support the printer
- The printer contains more than one protection counter
- The pads remain physically saturated
- A separate mechanical or electronic fault exists
For more information about the physical counter system, read the Epson Waste Ink Pad Counter Reset Guide.
Compatibility Checks Before Downloading
Complete the following checks before downloading or opening any Epson Adjustment Program.
Confirm the Exact Model
Check the model number on the printer label instead of relying only on the printer’s appearance. Some Epson printers use different regional names, suffixes, or firmware versions.
Confirm Windows Compatibility
Most adjustment programs are designed for Microsoft Windows. Compatibility can depend on:
- Windows version
- 32-bit or 64-bit architecture
- Printer driver installation
- USB communication
- Program age
- Security restrictions
Some older utilities may work on Windows 10 or Windows 11 only when they are run as administrator or opened in Windows 7 compatibility mode.
Use a Direct USB Connection
Connect the printer directly to the computer. Avoid Wi-Fi, network printing, adapters, docking stations, and USB hubs unless the model-specific guide confirms that they are supported.
Install the Correct Driver
Windows should recognize the printer before you launch the reset utility. If the printer does not appear in Printers & scanners, install or reinstall the appropriate Epson driver first.
Scan the Downloaded File
Adjustment programs are frequently distributed as ZIP or RAR archives. Scan the archive and extracted files with updated security software before opening any executable.
Security warning: Do not permanently disable antivirus protection or create broad exclusions for an unverified reset tool. A detection may be a false positive, but it should always be investigated before the file is allowed to run.
How to Reset an Epson Printer Using the Adjustment Program
The interface may vary slightly, but most supported Epson adjustment utilities follow a similar process.
Before You Begin
- Turn on the printer and wait until it becomes ready.
- Connect it directly to the computer using a working USB cable.
- Install the correct printer driver.
- Cancel all pending print jobs.
- Close Epson Status Monitor and other printer software.
- Confirm that the utility supports your exact model.
- Inspect the printer for visible ink leakage.
Step-by-Step Reset Process
- Download the correct utility. Use the model-specific guide for your printer.

- Click Initialization. Allow the utility to complete the process.
- Turn off the printer when prompted.
- Restart the printer. Wait for it to initialize fully.
- Run a test print or nozzle check.
A separate illustrated procedure is available in the Epson Adjustment Program reset tutorial.
After the Reset
- Print a nozzle check pattern.
- Confirm that the service warning is gone.
- Check whether warning lights continue flashing.
- Inspect the printer base for ink leakage.
- Avoid unnecessary head-cleaning cycles.
- Schedule physical waste ink pad maintenance when needed.
Common Epson Adjustment Program Errors
| Problem | Likely Cause | Recommended Solution |
|---|---|---|
| Printer not detected | Wrong port, missing driver, faulty cable, or incompatible utility | Reconnect by USB, reinstall the driver, select the correct port, and verify model support |
| Communication error | Unstable USB connection, printer not ready, or another utility using the port | Restart both devices, replace the cable, and close Epson background software |
| AdjProg.exe will not open | Incomplete extraction, security block, or Windows compatibility problem | Extract all files, scan them, run as administrator, and try compatibility mode |
| Unsupported model | The adjustment program was made for another printer | Close the program and use a model-specific utility |
| Initialization button disabled | No counter selected, printer not detected, or utility requires activation | Select the correct counter, confirm communication, and review the program requirements |
| Reset completed but error remains | Wrong counter, failed initialization, or physical printer problem | Check the counter again and inspect the printer for hardware or waste ink issues |
| Program freezes or closes | Driver conflict, missing files, security software, or unsupported Windows environment | Restart, re-extract the package, and test on a compatible Windows computer |
Printer Not Detected
If the reset software cannot find the printer:
- Turn off the printer.
- Disconnect the USB cable.
- Restart the computer.
- Connect the printer directly to another USB port.
- Turn on the printer and wait for Windows to recognize it.
- Confirm that the printer appears in Windows settings.
- Open the adjustment program as administrator.
- Select the correct model and port manually.
Communication Error
A communication error often means the software lost access to the selected printer port.
- Use another USB cable.
- Avoid USB hubs.
- Clear the print queue.
- Close Epson Status Monitor.
- Restart the Windows Print Spooler.
- Reinstall the printer driver.
- Verify that the reset utility supports the exact model.
Reset Completed but Service Required Still Appears
Turn the printer off, disconnect the power briefly, restart it, and use the Check function to confirm whether the counter value changed.
If the value did not reset, the initialization may have failed. If the value reset but the warning remains, the printer may have another counter or a separate hardware error.
Flashing Lights Continue After Reset
Flashing lights are not always caused by the waste ink counter. They may indicate:
- Paper jam
- Open cover
- Carriage obstruction
- Scanner error
- Ink system problem
- Sensor or motor failure
Use the common Epson printer troubleshooting guide before repeating the reset.
Do You Need to Replace or Clean the Waste Ink Pads?
In many cases, physical maintenance is recommended. The counter estimates the amount of waste ink generated, while the pads collect the actual ink.
Signs the Waste Ink Pads May Be Saturated
- Ink leaking from the bottom of the printer
- Visible ink around the maintenance station
- Strong internal ink smell
- Service warning returning soon after reset
- Heavy long-term printer use
- Ink stains underneath or behind the printer
Maintenance Options
Replace the Waste Ink Pads
Replacement is generally the most complete repair. The saturated pads are removed and replaced with suitable absorbent material. Some models require extensive disassembly, so technician service may be appropriate.
Clean the Existing Pads
Experienced users may remove, clean, dry, and reinstall the pads. This process is messy, and incomplete drying or incorrect reassembly may cause leakage or moisture damage.
Install an External Waste Ink Tank
An external tank redirects discharged ink into a separate container. It may be useful for high-volume printers, photo-printing businesses, or sublimation setups.
The installation must be completed correctly. A loose, blocked, pinched, or incorrectly positioned tube may cause ink leakage or pressure problems.
How to Reduce Waste Ink Buildup
- Avoid unnecessary head-cleaning cycles.
- Use the printer regularly.
- Turn the printer off with its power button.
- Use suitable ink.
- Limit unnecessary borderless printing.
- Run a nozzle check before repeating head cleaning.

Some versions work on Windows 11, while older utilities may require administrator permission, compatibility mode, or another supported Windows computer.
Does it work on macOS?
Most Epson Adjustment Programs are Windows-based and do not run natively on macOS. A physical Windows computer is generally more reliable than a virtual machine for USB printer communication.
Why does antivirus software detect AdjProg.exe?
Some older or unsigned utilities may trigger security warnings. This does not automatically confirm malware, but the file should be verified and scanned before use.
Is the Epson Adjustment Program free?
Some model-specific utilities are distributed without charge, while other reset methods may require a key, paid utility, or technician service.
Is WIC Reset Utility better?
That depends on model compatibility and the required service function. WIC Reset Utility is more standardized, while an Epson Adjustment Program may offer additional model-specific maintenance options.
Why does the Service Required error remain after resetting?
The wrong utility or counter may have been used, initialization may have failed, the printer may contain another protection counter, or the error may be caused by hardware rather than software.
Can the resetter fix all blinking-light errors?
No. Blinking lights may also indicate a paper jam, carriage obstruction, open cover, scanner problem, sensor fault, or another hardware condition.
What should I do if the reset fails?
Verify the exact model, reconnect the printer by USB, reinstall the driver, try the correct utility on a compatible Windows system, and seek technician service if the warning continues.

Final Advice
The Epson Adjustment Program can be useful when a supported Epson printer stops because its waste ink protection counter has reached the programmed limit. The safest approach is to identify the exact printer model, use a matching utility, connect the printer directly by USB, check the counter before initialization, and restart the printer only when prompted.
Remember that the reset is a software procedure, not a complete physical repair. If ink is leaking, the warning returns quickly, or the printer continues to malfunction, inspect or replace the waste ink pads and arrange professional service when necessary.
