So this is a new printer to me as I?m just beginning. (Birthday gift). Well I?ve gone through and built the printer no problem, but the wiring is not to detailed. The power unit seems to be the issue though. I wired in the plug as the diagram shows (blue wire in slot 1, brown wire in slot 2) and when I plug the unit in I get either sparks coming from the outlet before fully plugged in and/or pop a fuse. I did swithbthe power unit to 110v and checked all the breakers in the house whichbare all 120v breakers. Any idea what I am doing wrong here?
