If the reset fails or message returns

• Ensure the USB cable is direct (avoid hubs) and drivers are up to date.
• Reboot PC and printer, then retry.
• Try running the utility in compatibility mode (e.g., Windows 7/8) if using a newer OS.
• If the waste ink pads are saturated, replace or clean them — resetting without servicing pads may lead to immediate re-triggering or internal leaks.

Step 5 – Aftermath.
The waste ink pad physically remains the same. You must manually open the printer, remove the pad (usually under the right side of the printhead chassis), wash it with distilled water, dry it, reinsert it, or replace it with a third-party pad kit ($8 on Amazon). If you skip this, the pad will eventually overflow, leaking ink out of the bottom ventilation slots. Ensure the USB cable is direct (avoid hubs)

Part 2: Why Does the Epson L5190 Need a Reset Tool?

Unlike older printers where you could manually replace a waste ink tank, the L5190 is a sealed system. Epson designed it to stop working after a certain number of cleaning cycles—not because the printer is broken, but because the internal sponge is theoretically saturated.

Remember to be mindful of the physical waste ink pads. Resetting the counter tells the printer the pad is empty, but physically, it may still be full. Regular maintenance ensures your L5190 keeps printing for years to come.

Step 2 – USB isolation.
The tool requires a direct USB connection. You must disable your antivirus (false positives are near-certain because the tool hooks directly into USB low-level drivers). Experienced users run it on an old laptop with no network connection.
