Here's a solution for that.
I'd strongly suggest trying the Print Diagnostic Utility first.

My C6180 had the same problem. Apparently some defective components were used in the construction of the logic board (see photo). On my C6180 there were 3 failed capacitors (the green cylinders - the puffed top indicates failure) and a 4th from the same manufacturer (TEAPO - many unfavorable web references to this manufacturer). I purchased 3x 330uF 16V and 1x 680uF 10v rated to 105 degrees Celsius (total about 60cents). On the logic board, the capacitors I replaced are labeled C613, C614, C660 and C662. If you are not comfortable replacing the parts yourself (or don't have a soldering tool), you will have to find someone who will. The time to repair should be less than 30 min - I did it in 25 min with only a solder pen. This fixed the on and off problem and also fixed the ink system failures the printer was having. A similar fix may apply to other printers .
