The most common and reliable way to reset the L3252 is using third-party software called (Waste Ink Counter Reset). This tool communicates directly with the printer’s firmware.
Use this if you want to clear network settings, language, or other custom configurations.
This is a software fix. Physically, the ink pads inside your printer are likely saturated. If you reset the counter without replacing the pads, you risk an ink leak in the future. Use the reset as a temporary fix and consider having the pads serviced professionally.
