We have had this a little over a year and it has worked fine.  Don't use it much.  BUT today it slowed way down and then all three lights on the left started  blinking...won't shut off.  We had to unplug it.  We let it cool down...now when we plug it in it does not heat and all three lights at left blink....not heating at all but will feed a piece of paper slowly. Disappoinmted that there are no instructions in the manual that covers this problem
