VNIT Reset Tool user guide

Screens below are from version 3.17.0 (October 2026), taken on Windows.

Before you start

1. Download and open it

Windows 10 or 11 (64-bit): download the recommended zip from the download page. Windows 7 or 32-bit Windows: download the second zip.

1. Right-click the zip and choose Extract All. Open the new folder, then the VNIT_Reset folder inside it.
2. Double-click VNIT_Reset.exe (the file with the VNIT icon). The folder also holds many library files the app needs, so keep them together; for a desktop icon, right-click VNIT_Reset.exe → Send to → Desktop (create shortcut). There is no installer and it needs no admin rights. Windows steps with screenshots.
3. If Windows shows “Windows protected your PC”, click More info, then Run anyway. Why this appears.

Do not run the app from inside the zip without extracting it. Windows only shows the files in a zip. The app cannot save your key from there.

Mac (macOS 11 or newer, Intel or Apple silicon): download the Mac zip, unzip it and open VNIT Reset from the folder. macOS asks you to confirm the first time. Step-by-step for Mac.

When the app opens it shows the Dashboard, still empty because no printer is connected yet.

2. Connect the printer

Use a USB cable. It works on every supported printer. Reading and resetting over Wi-Fi works on a few models only (for example the L805). Most models, including the L5290 and ET-2800, must be connected by USB.

1. Connect the USB cable from the printer to the computer.
2. Switch the printer on and wait until it is quiet.
3. Press Connect (top right) or Check Printer. The app looks for the printer over USB and Wi-Fi by itself.
4. The bar at the top shows PRINTER MODEL, SERIAL and PORT, and the status changes to Connected.

Wi-Fi (a few models only): on a model that supports it, the printer and the computer must be on the same network, and a printer that has just been switched on can take up to a minute to join Wi-Fi. If the app finds the printer on Wi-Fi but the printer does not allow its counters to be read that way, the reset buttons stay locked and the log says so. Plug in the USB cable and press Check Printer again; the buttons unlock once the counters are read.

If more than one Epson is connected, the app asks you to choose one.

3. The screens

The menu on the left has five screens and a chat button:

The System log at the bottom of the Dashboard records every action, and the reason when something fails. If you press a button and nothing seems to happen, read the log first.

4. Read the counter (free)

With the printer connected, press Check Printer. Reading takes about 10 to 20 seconds; do not press again or unplug the cable meanwhile. Most printers show two gauges:

Under each gauge, Points is the current count and Limit is where the printer stops. Some models are not calibrated as a percentage yet; they show the points only and reset the same way. More about the numbers.

5. Free trial reset

The Free trial reset button (gift icon) sits next to Reset all while no key is entered.

• Once per printer. Trials are counted on our server, so reinstalling the app does not give another one.
• The counter must be at 90% or more. Below that the trial would not lower anything, so the app keeps it for later.
• It brings the counter down to 80%, not to 0%. The error stops and the printer prints again.
• If a trial fails part-way, it is not counted.

Press it, read the box, and press Use trial now. Then confirm the reset and switch the printer off and on, as in steps 6 and 7.

More about the free trial.

6. Reset to 0% with a key

Keys look like VNIT-XXXX-XXXX. Buy a key (US$6 for one printer). It arrives by email straight after payment.

1. Connect the printer and press Check Printer.
2. Press Reset all (or Reset Main Pad / Reset Platen Pad for one pad only). Without a key, the app opens the License screen.
3. Paste the key into RESET / LICENSE KEY and press Activate.

4. The app goes back to the reset by itself and shows Confirm reset with the printer model and serial. Check that they are your printer, then press Confirm reset.

Lost the email with your key? Press Lost your key? Email me a link to it on the License screen, or go to My keys.

7. After the reset: turn the printer off and on

This is required. The printer only reads the new value after a restart. Skip this and it keeps showing the old error. The app shows what to do:

1. Turn the printer off with its power button. Wait until all lights are off (some models take 20 to 30 seconds).
2. Turn it back on and wait until it has finished and gone quiet (usually 1 to 2 minutes).
3. Over USB, the app notices the printer going off and coming back, and reads the counters again by itself. If it has not re-read yet, press The printer is back on – read the counters after the printer has gone quiet.

The gauges should now show 0% (or 80% after a trial).

Then check the pads. The reset clears the counter, not the ink. Pads that are soaked need washing, replacing, or an external waste ink tank. Otherwise ink can leak out of the printer. How to handle the pads.

8. Head cleaning and nozzle check

Under Maintenance & tools on the Dashboard:

Every cleaning sends ink to the waste pads, so do not run it again and again without a reason.

9. Settings

10. Troubleshooting

Every message the app can show, with step-by-step fixes (including Windows 11 driver problems): the tool cannot find, read or reset the printer. Errors in the app have a “How to fix” link to the right part of that page. The short version:

For anything else, turn on Verbose logging in Settings, try again, and send us a screenshot of the app in Chat with support or on WhatsApp or email.

11. What the app sends to our server

The printer model, its serial number, a computer ID, the key used and the result of each reset. If you turn on Send error report to support, also a read-only copy of the printer’s memory, once. We use this to check keys, count free trials and help when something goes wrong. It does not read or send your documents or anything you print. Privacy policy.
