Query: Lexmark Z65n is a fire hazard!

I thought I smelled smoke for a couple of days around the house but couldn't figure out the source. Then I tried to print something on my Lexmark Z65n and noticed that the printer was not powered up and I couldn't turn it on with the power switch. I pulled the power supply out of the printer body (strange design) and it was red-hot and melted. Very dangerous piece of equipment here and something really bad is going to happen unless there is a recall. This is the third Z65n I've had since Lexmark has had to send me two replacements for other problems. I'm not impressed to say the least.
