I've had this printer for 3 years. There were no real problems the first year. Then, one day, I ran a light cleaning and it wouldn't stop cleaning. As soon as the 3.5 minute cleaning cycle ended, it started another cleaning cycle, and another, and another. It did this for 5 times, before I hit the power-off button. I left it turned off overnight and the next day it was back to normal, no more continuous cleaning. About 5 or 6 months later it started doing continuous cleaning again. Like before, I hit the power button and the next day it was back to normal. About every 5 or 6 months it does this. Has any one else here ever had the same experience? Is there a fix for this?
