How to reset a Samsung ML-2165 printer (detailed guide)

Below are step-by-step methods to reset your Samsung ML-2165 (ML-2165W/ML-2165K variants) for common issues: clearing error states, resetting toner/maintenance counters, and restoring factory defaults. Follow the sections that match your problem.

Restart: Reconnect the power cable and turn the printer back on. 2. Toner Counter Reset

Hold down the WPS (Wi-Fi) button on the printer control panel for about 10–15 seconds. The status LED will blink rapidly and then turn solid.

The ML-2165 is a workhorse, but its aggressive page counting and sensor sensitivity mean you will likely need to reset it multiple times over its life. Bookmark this guide – the next time your printer flashes a false "Toner Empty" warning in the middle of a critical print job, you will know exactly how to bring it back to life in under two minutes.

• Use quality toner: Cheap toner can leak and cause sensor errors.
• Reset after every refill: Perform the “Stop button trick” immediately after replacing toner.
• Keep drivers updated: Old drivers can misinterpret error codes.
• Avoid power surges: Plug into a surge protector to prevent memory corruption.
• Clean the corona wire: Use the green cleaning lever inside the toner cavity (slide it back and forth 5 times every 2 weeks).

• You must purchase a reset chip/fuse specific to the ML-2165 cartridge (often a small white plastic block with contacts).
• Install the chip onto the side of the toner cartridge. When the printer powers on with the new chip, it blows the fuse and resets the counter automatically.
