I purchased this printer to use for business idea but decided to go a separate direction. I performed a full diagnostic test in the menu where the unit moved up and down in different access and rotations and turned on both fans and both of them turned on and the result was is past the test fully and found no errors and I've included a picture of the test in the photos. It includes the wire that you see here I believe it's already inside the unit so I need to heat up before it can be removed and everything that you see in this photo is what it will be included nothing besides what is showing will be included. I do not accept returns so please ensure that this is exactly the right unit for you and ask any questions and review all photos prior to purchasing thank you
