printer typically involves different procedures depending on whether you need a simple memory clear to resolve errors or a "firmware reset" to bypass toner chip limitations. 1. Soft Reset (Memory Clear)

Some users use third-party "Fix Firmware" to reset toner counters to 100% and allow the use of refilled cartridges without a chip.

This is an unofficial modification and may void your warranty. It typically involves dragging a specific firmware file onto a usbprns2.exe usblist2.exe tool while the printer is connected via USB.

8) Common LED/error behaviors and quick meaning

• Single blinking LED during power-on: normal initialization.
• Rapid blinking or alternating LEDs after power-on: indicates an error or Service Mode entry.
• Solid error LED + no printing: check paper jam, open covers, or toner cartridge seating.

Part 8: Preventing Future Resets

After successfully resetting your Samsung ML-2165, follow these tips to minimize future issues:

• Use high-quality compatible toner – Cheap cartridges often have defective chips or poor gear alignment.
• Never turn off the printer during a print job – This can corrupt the NVRAM.
• Clean the paper feed rollers every 6 months. Dust causes false jams.
• Update the firmware – HP still offers legacy firmware for the ML-2165 on its support site. Newer firmware can resolve false error messages.

3. How to Reset the Page Counter (Main Board)

Note: This typically requires specialized software (Service Mode) and is usually not necessary for home users.

1. Connect the printer to the computer via USB.
2. Put the printer into Service Mode:
   • Press and hold the Cancel/Stop button for about 4 seconds until all LEDs blink.
   • Open and close the top cover (toner lid) 4 times.
3. Once in service mode, you must use Samsung service software to click "Reset Counters."

3) Service mode reset (resets toner/maintenance counters)

Warning: Service mode performs deeper resets; follow exactly. If unsure, use a manual or authorized service center.

1. Turn the printer off.
2. Press and hold the Stop/Clear (sometimes “Cancel”) button.
3. While holding Stop/Clear, press and hold the Power button.
4. Release the Stop/Clear button while continuing to hold the Power button.
5. Press the Stop/Clear button five times (or the sequence required by your model — typically 5).
6. Release all buttons. The printer should enter Service Mode (LEDs will show a pattern).
7. To clear the toner counter: press the Stop/Clear button a specific number of times (often 1–4) to select “Toner Reset,” then press Power to confirm. To clear the drum/transfer/maintenance counter, select the corresponding option in Service Mode and confirm.
8. Turn the printer off and on to exit Service Mode.

Because Samsung ML-2165 variants differ slightly, the number of button presses to navigate Service Mode can vary. If the sequence above doesn’t work, consult a model-specific service manual.
