| Setting | How to restore | |---------|----------------| | Wi-Fi (ML-2160W / 2165W only) | Use Samsung Easy Printer Manager or WPS button (press Wi-Fi button on printer, then router’s WPS within 2 min). | | Power save time | Default is 20 minutes. Change via printer settings menu (hold WPS/Wi-Fi button for 5 sec to enter menu on W models). | | Emulation mode | Default is HP PCL6. To switch to Samsung Print Language (SPL), hold Cancel for 15 sec at idle. | | Symptom | Possible cause | Solution | |---------|---------------|----------| | No LED change during reset | Timing too slow | Repeat Phase 2 faster (under 2 sec between presses). | | Printer still shows “Jam” | Physical jam or sensor stuck | Clean paper path and sensors; then repeat reset. | | “Toner not compatible” returns after reset | Toner chip is permanently locked | Replace toner chip or use an auto-reset chip cartridge. | | Wireless button flashing continuously | NVRAM corrupted | Perform reset 3 times consecutively, then re-flash firmware via USB (download from Samsung/HP support). | 8. Conclusion The firmware reset procedure for Samsung ML-2160, ML-2165, ML-2160W, and ML-2165W is a button-timed sequence that clears NVRAM and resolves many persistent errors. It is non-destructive to the engine’s page count but erases all user settings. When executed with precise timing (steps under 2 seconds), success rates exceed 90% on functional hardware. For printers that remain unresponsive after three attempts, re-flashing the official firmware via a Windows PC using the Samsung Firmware Update Utility is the next recommended step.
