My old (new in 2006; now 2022) Samsung ML-2010 did not come back on after a power outage. The LEDs were flashing alternately: "On Line / Error" flashed red and "Toner Save" flashed green. There was a motor running continuously inside.
The cause was a bad power supply capacitor (1500 uF, 10 V, 10mm dia, 20 mm tall) that was obviously "puffy".

This is the easiest printer to work on that I have ever seen.
I took out the paper and closed the front flap so I could lay the unit on it's front.
There is a cover on the back with a screw at each side (near AC inlet and near USB port). Just take out those 2 screws and pop the cover off. The bad capacitor was near the top, middle of the power supply board. Disconnect the 2 cables, remove 5 screws (2 sizes--keep track), open the top cover (to release the microswitch interlock) and push the paper tray sense lever (at the bottom--it flags an optical sensor on the board) then lift the board out.
I unsoldered the old capacitor and soldered in a new one, put it all back together and it works great again!

Hi.Are you having any kind of problem with the printer? I only ask because this is normal for the Samsung ML 2010, I have two and they both do this when I switch them on and I have no problems with either. If you are having a problem post back and I will try my best to help you out. Hope this helps. Si :)

Samsung ml 2010 in when start print tow led blinking

Hi

Think you may need to be a little clearer with your question to get any sensible answer. If you ar referring to the toner light flashing then you simply need to buy a new toner and replace it.

Stopped printing after I installed new Toner!

If the new toner is original, your unit just burned the fuser. If it is under warranty, any Samsung Authorized Service Center will gladly replace it for free.
