My old (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!
The cartridge reach end of life, replace the fuse for a new one (63mA or 100mA)

Your system has some problems. If this problem occurs, contact your service representative.
A toner cartridge has almost reached its estimated cartridge life[a]. It is recommended to replace the toner cartridge. (SeeReplacing the toner cartridge.)
Blinking
A minor error has occurred and the machine is waiting for the error to be cleared. When the problem is cleared, the machine resumes.
Small amount of toner is left in the cartridge. The estimated cartridge life[a] of toner is close. Prepare a new cartridge for replacement. You may temporarily increase the printing quality by redistributing the toner. (See Redistributing toner.)
