| Error | Solution | |-------|----------| | “Communication error” | Use USB 2.0 port (not 3.0). Reinstall Epson driver. | | “Model not supported” | You have wrong version. Get AdjProg 4.2.1 or newer. | | “Key invalid” | Run keygen as admin. Match exact model (M2110, not M2110A separately). | | “Reset failed / timeout” | Turn printer off/on, enter Service Mode again via program. | | Counter stays 100% after reset | The waste ink module is physically full – replace or clean sensor. |
