If you are experiencing problems with your Samsung ML-2240 toner printer regarding the toner counter, you may need to reset it. Printers will sometimes show the incorrect toner levels. Alternatively, if you are refilling the cartridges yourself, you will want to reset the counter manually. With the Samsung ML-2240, you do not reset the cartridge--you reset the machine itself. This will void your warranty, so only proceed if you are sure that you want to. This method will reset the toner counter every time your printer is turned on.

Tips and warnings
- If you do not want to solder the clips together, you can use a paper clip instead. Hold the paper clip with pliers over both the first and fourth pins. Turn your printer on and hold the paper clip in place for around five seconds. Wait until the printer turns on properly, then switch it off. Remove the clip and replace the back cover.
